Convert Windows 7/8/10 Installation from Legacy to UEFI Without Data Loss (Simpler Method)

[@NehalJWani]

I have created another video in this series, which might be even simpler than this method. It is available at kzbin.info/www/bejne/m6XGq6eJhsp7q6M

[@aminipo8829]

Brother only you can help me out. Please reply. I did as shown here. After shrinking the partition i couldnot perform the next commands. It said there is no partiotion on the disk. So i freaked out and turned off the pc. Tried to boot but it was unable to find any bootable device.

[@aminipo8829]

Please tell me what should do. Do i install fresh copy of windows?

[@bilowik123]

Honestly for a voiceless video that was extremely easy to follow, very detailed, and I rarely had to go back and relook at certain bits. Thanks so much

[@alaguiza8541]

thanks for the great tutorial but i have one question ; after creatited EFI partition min 9:52 u have not to select the EFi made partititon before formatting ? you type format command on selected partition 2, this will not format the entire partititon not only the one reserved for the efi ??

[@NehalJWani]

Type: list par In the output, you'll see the partition which is selected (there is an asterisk (*) symbol marked on the selected partition)

[@alaguiza8541]

@@NehalJWani yes but I think in your tutorial you miss a very important step after creating the efi partition u miss to select the new partition before formatting , right ???

[@NehalJWani]

@@alaguiza8541 When a new partition is created, it is selected by default.

This is slick! Worked great! The only problem I had was at the very last step It may be because I'm using the US version, but the command, "bcdboot D:\Windows /1 en-us /s Z: /f ALL" Didn't work for me. Since the en-us specification is default, I just typed, "bcdboot D:\Windows /s Z: /f ALL" and it worked like a charm. Just a heads up in case anyone else runs into the same problem!

[@NehalJWani]

Again, it is /l (small 'L') and not /1 in "bcdboot D:\Windows /l" Thanks for the feedback! :-)

Thank you very much, @Nehal! Only a question: I have unformatted free space after my Win part. Could I only create the EFI partiton without shrink my Windows partition? Will the EFI part go before or after the present Win partition?

[@NehalJWani]

You can use the existing free space to create the EFI partition. Just make sure it is at least 100MB in size.

@@NehalJWani Thanks, Nehal! :-)

[@OL92800]

Well done : I have followed your tutorial to shift to uefi for a dell latitude 3550 after an upgrade to windows 10 in legacy bios boot mode and It works beautifully. There are some commercial soft to do this more easily, but your tutorial may spare some money to technical oriented people.

[@NehalJWani]

Glad to be of help! :-) I wish people don't spend money on stuff that they can do easily.

[@MauricioCervantes]

Great tutorial, with some practice i could finish every machine in 2 minutes. Quick question: Now when i go to disk management on my win10 i still found the system reserved partition because i didn't use the del par override, can i delete that partition using disk management of win10?

[@NehalJWani]

+Mauricio Cervantes I am not sure if disk management will let you delete that partition. But you can always open an elevated command prompt, run diskpart, sel the partition, and use del par override

[@tuantran-gj7oh]

Hello there, just a noob with questions: 1. currently I am having a 500gb external hard drive, a licensed win 8.1, and a uefi compatible laptop. The laptop does not have any OS yet (yes I encountered some error with win10 and changed eufi mode to legacy). If I follow your instruction on creating bootable usb which is eufi compatible, can I access the bios, change back from legacy to eufi, THEN start booting windows from bootable usb? 2. Is it true that the flash drive you are using to boot in this video is MBR not GPT? Very appreciate the video, and would very appreciate it if you reply me as soon as possible :D Thank you

[@NehalJWani]

+tuan tran Is the licensed Windows installed in Legacy mode? For installing Windows in UEFI mode, the flash drive has to be booted in UEFI mode. I do not understand your question completely. Send me a request on hangouts for quicker replies.

[@tuantran-gj7oh]

+Nehal J Wani just sent a message to you on hangout

[@Playaheat]

This worked like a Charm!!! Real easy to follow along and get it done! Great video along with your others!!!

[@RapttorX]

@Nehal J Wani Thank you, it worked like a charm without losing anything. BUT I have a question: i still have the system reserved(350mb), recovery partition(450mb). Are those 2 still used in GPT-UEFI or i should remove them ?

[@NehalJWani]

I don't think they are required.

[@EricShotheKingSho]

Sir can you help me? When I type the bcdboot into the CMD, it didn't show the word successfully copy boot file. Instead, it show the guide to use the bcdboot. I've already select the right disk. Why it show that? Now I can't either revert it. So it ended up by saying operating system not found

[@NehalJWani]

+Eric Sho Are you doing this for Windows 7? If yes, then please read the video description. You need an advanced version of bcdboot binary. If you are doing this for Windows 8/10, then please type here the exact command that you are typing.

[@EricShotheKingSho]

I'm doing for Windows 8.1. I've following all the procedure from start to finish. On the bcdboot, I'm type bcdboot F:\Windows /1 en-us /s Z: /f ALL F is the location where Windows is installed

[@EricShotheKingSho]

But instead of saying successfully copy boot file, it show on how to use bcdboot

[@NehalJWani]

+Eric Sho Dude, you are typing wrong command. You have to type: bcdboot F:\Windows /l en-us /s Z: /f ALL Please note the difference. I am typing small 'L' and you are typing numeric '1'.

[@EricShotheKingSho]

Now it show's failure when initializing library system volume. Maybe I should format it and retry it. When I try to refresh Windows 8.1, it say that the drive where Windows located is lockes

[@GIJOE3k]

Hello Nehal! Will this work with with a Windows 7 install? In other words, will the windows 10 iso(part of step 3) work for a windows 7 install that's going from legacy bios to uefi? Thank you for your time! :)

[@NehalJWani]

+GIJOE3k Yes. You can use Win10 ISO for converting Win7 to UEFI. With the bcdboot command there will be a small warning, which you can ignore.

[@GIJOE3k]

+Nehal J Wani Awesome, im going to try it out tonight! Will let you you know how it goes. :)

[@mitch832]

Thanks buddy. Just made a fresh install by first installing Windows 7, and without even updating drivers, just went straight to Windows 10 update. Then checked all the drivers and now also made the UEFI conversion. As a Windows-guy, now I just keep shutting the laptop down and powering it back on just for fun. Every time it catches me like "HOLY SH*T!!". 10 seconds from power-on to Windows desktop :O And it's a 3-4 year old HP laptop, nothing new or fancy.

[@ashersyed7462]

hi Nehal.. I have Linux 7 that needs to be installed on Oracle x72 hardware .. UEFI boot usb creation seems impossible .. it wont detect .. any help there

[@NehalJWani]

What method did you use to creating the bootable USB?

[@ImSoBlack1609]

It looks like the Windows 10 setup file I downloaded from Microsoft can create a bootable USB. Should I use that or should I follow your guide in the other video?

[@NehalJWani]

+StrayCat95 You can use either method. We just somehow need a Windows Recovery Environment, where we can play with the command prompt. :)

[@ImSoBlack1609]

+Nehal J Wani Thank you! Everything works wonderfully :D I have a question though. Why do we need a 200MB hidden partition? Does it need to be 200MB or could we have made it smaller? I'm just a bit curious :) it seems to me this is a patch more than a conversion? Like, do we need that hidden 200MB partition if we were to install Windows from scratch?

[@NehalJWani]

UEFI specs require the presence of an ESP (EFI System Partition) with a fat filesystem. You cannot skip that. The size of this partition should be enough to hold the boot configuration data. It can be less than 200 MB too.

Hi, your tutorial is really good and useful. I have a question, if i wanna delete Reserved Windows partition, i shouldn't use shrink, then after: # sel par X (Replace X with the System Reserved Partition) # del par override Should i follow with: create par efi format fs = fat32 quick # Format this with fat32 file system assign letter = Z: ... Normally? Thanks dude!

[@NehalJWani]

+Iván Portilla Yes, you can do that.

Hi Nehal J Wani Today i followed the step by step of video but every thing went well for windows8.1 enterprise 64bit in PC Model Dell OptiPlex 9020 but result was not changed BIOS Mode from Legacy to UEFI still showing Legacy. Can you please help me in this regards.

[@RyanSandlin]

on step 7, when I type in gdisk64.exe -1 6: (the windows drive is indeed 6 in disk util) and hit enter it did not show me the partition table scan as it did for you. It would just say Usage: gdisk64.exe [-1] device_file. what does that mean? thanks in advance!

[@RyanSandlin]

to add to this comment, if I try to move on to the next step buy typing gdisk64.exe 6 it says "problem opening 6 for reading!"

Great tutorial, I must say. It worked like a charm, I just did one mistake. I previously had 20 GB of unallocated space for Installing Ubuntu when I came across this UEFI/Legacy issue. After completing the method as you described, The EFI partion is covering up 20 GB of space, any idea on how to shrink it?

[@NehalJWani]

+Sandeep Mishra Yes, that is easy. Go back to the command prompt where you create the efi partition. Then type the commands: diskpart sel disk 0 list vol (note down the partition number for the Windows partition, let's call it Z) list par (note down the partition number for the 20 GB EFI partition, let's call it X) sel par X del par override create par efi size = 200 format fs = fat32 quick assign letter = B: exit bcdboot Z:\Windows /l en-us /s B: /f ALL (Replace Z with the drive letter of the Windows partition) Then reboot :)

are there any differents between this method and clean installing of windows 10 on eufi mode ?? If Yes, what is the best your method or installing a new windows? I do not want to lose my files and windows and in the same time do not want to get any issues after applying your method.

My method doesn't delete any files.

[@rosannypena5709]

it does, and also broke it, no matters if u follow perfectly ur steps... thanks for being close to fuc* up my pc!!

[@NehalJWani]

Nope, it does not. If you it happened with you, then you are doing something or wrong or not following the steps correctly. It may be the case that your partition table got screwed up and can still be fixed. If you need help with that, reply to this comment.

[@dimitriosklitsinikos2056]

Hi! I'm having a problem navigating into the location of the binary. i'm using a bootabla windows 10 usb but i'm stuck in this step. Can you tell me what to do? i have put the binary exactly in the same location as you did.

[@NehalJWani]

In order for me to help you, please share the output for the following commands: diskpart list disk sel disk 0 list par list vol Take a picture using your smartphone and upload it on picpaste.com and share the link here.

[@NehalJWani]

@Brian R. Look at the output for: diskpart list vol exit You'll see the drive letter assigned to your existing partitions. Then let's say the partition where you put that gdisk binary is at J:\gdisk , you'll need to type: cd /d J:\gdisk It can be the case that the drive letter you see when booted inside Windows are different compared to here.

[@amjathali8937]

hey .... what does u mean the partition letter in the recovery environment..... ??? while mine is booted in H drive so while giving that it saying "The device is not ready"

[@NehalJWani]

You have to boot in the Windows Recovery Environment from an external media.

[@pixcled9365]

I did this but when I try to boot it says "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key" and when I do plug in my Bootable USB it just goes to the installation screen. I had no errors when doing all the commands.

[@pixcled9365]

I deleted the boot directory, not shrink. (Does that matter?)

[@pixcled9365]

Also when I tried to redo this it says MBR: protective and GPT: present

Thank you very much Nehal J wani, this video solved my problem. Everything was so easy to follow and I raised BRAVO Nehal slogans when I see my windows is converted from Legacy to UEFI mode without any new installation. I have one problem now, when I try to make a "system repair disc" it says the files to create a repair disc are not present. Could you please help what should I do to create a repair disc so that when in the future I have some problem I have the repair disc for a rescue (I don't have the windows installation CD). Secondly in "This PC" the 500Mb partition is automatically shown as "System Reserved (D:) (465 MB free of 499 MB)" drive separately, can I delete this manually will it cause any problem? Many thanks once again.

[@NehalJWani]

Which version of windows is this? If it is 8 or 10, you can download the installation media from Microsoft's website. You can delete the 499 MB partition

Thanks!! It worked for me for Windows Vista, 7, 8.1 and 10 and helped me a lot. Some people may have problems with Windows Vista or 7 in UEFI Class 3 for not supporting the INT10 video mode, supported by UEFI Class 2 in a hybrid mode between UEFI and CSM.

[@francescoimpellizzeri6532]

hello I wanted to understand how it works instead of a Windows 7 operating system just to know you do since you work with the commands cmd startup instead of inside the pc?

[@NehalJWani]

In the video I make changes to the partition table, which is not possible while the operating system is booted. Hence I shut down the operating system and use an external media to do so.

[@neverwasthere]

Some more detailed observations: The EFI system partition created by this method is placed behind the Windows partition, which is unusual. The restriction on booting after conversion is that boot order has to be set as either "UEFI only" or "Both, UEFI first". The default boot setting for Lenovo ThinkPad with "Both, Legacy first" won't boot the computer.

[@NehalJWani]

I think that is expected.

[@egparadigm1091]

When i run the final command it says "failure when attempting to copy boot files". Verbose says it cannot access the files. at an earlier stage i had to run dskchk - dont know if this related?

Hi, thanks for the video! The process worked for me, except when I attempted to boot in UEFI mode. The only deviation I made in the above process was instead of shrinking, I deleted System Reserved (for me it was only 100MB) and used that for the efi partition. After restarting, the computer makes it past BIOS, but is unable to find anything to boot and instead gives me a black screen with a blinking white cursor. Any thoughts on why this happened and how to fix it? Thanks.

[@NehalJWani]

+N8Stewart In your BIOS settings you need to disable Legacy and Enable UEFI.

+Endlesspathable Update: Attempted the conversion with all other drives disconnected (of course noted the renumbering in list disk/vol), and unfortunately still same error. I believe the error may be more related to an ASRock Z97 Extreme6 motherboard bios issue, as bios 2.50 does not correctly identify the Samsung NVMe 950 Pro SSD (per ASRock tech). So with that in mind, I will wait till the next BIOS update and try again then. In the meantime I will stay in legacy boot mode and post my next attempt post bios update!

If I'm not interested in keeping any of my data would just formatting my drive, changing boot type from legacy to uefi in bios, and installing windows 10 work ?

[@NehalJWani]

+Alexandru Parausanu Yes, but you will have to make sure that you change the partition table from MBR to GPT and boot the Win10 installation media in UEFI mode.

[@NeoExHades]

I mounted windows 10 ISO with Rufus on a USB flash drive, and I checked MBR intead of GPT file system, as a result after OS installation, I could not enable secure boot nor fast boot in my ASUS laptop BIOS, which sucks because those two bios features are IMO must-have-enabled features. Will this method in the video un-grey out the features in my BIOS ? Or do I have to re-install Windows 10 ? I'm asking because it would be great if the method of the video would allow what I want to do, since it's faster than reinstalling the entire OS as well as having to download all the apps again :'(

[@NehalJWani]

Yes, after this method, you will be able to use secure boot.

Partition table applies to all partitions on a block device. It doesn't make sense of converting one partition to 'GPT'. We convert the partition table not partitions themselves.

Did all the steps (on Windows 7, with a Windows 10 Recovery USB), and everything went smooth. But, when i go to msinfo32, there's no BIOS MODE entry. I checked Google, and it was also suggested a .log file from C:/Windows/Panther (setupact.log). The Detected Boot Environment is BIOS, so i'm guessing i'm still, somehow, booting in Legacy. Can you help me out? Thank you for a great share :)

[@NehalJWani]

Setupact.log is only created during installation of Windows. Can you go to the command prompt, type: diskpart list disk And see if there is an asterisk symbol (*) in the GPT column?

[@jppmarujp]

Hello Nehal. Yes, there is and asterisk in the GPT column. Does that means that it's booting in UEFI?

Nice explanation :)But.... at step 10 you let the use dangling around a bit: how to start in UEFI?! Because I the user had a working Win10 system, booting from a MBR disk, they were booting from MBR/BIOS. After changing the MBR disk to GPT the system will not start unless you make changes to the BIOS (AND you have to check PRELIMINARY (before you do ANYTHING) whether the motherboard is capable to start via UEFI and how to change the settings. (For experienced users this is clear, but for newbies it can be a pitfall.)

[@NehalJWani]

Thanks for the comment. I'll add an annotation in the beginning stating that the user's mobo must be UEFI compatible and he should read his mobo's documentation to know how yo switch the boot mode.

[@gvklaveren]

+Nehal J Wani Thanks!

[@munsoormalik8449]

I tried this but it has not worked for me. I now get inaccessible boot device errors. I am pretty sure I did this right. Any suggestions??

[@NehalJWani]

Are you sure you are booting in uefi mode? what is your computer make/model? what values do you see for boot option #1 in BIOS boot settings?

[@dougiewatt4183]

Hi mate, i've followed right through your tutorial, until I get to the very end, and run bcdboot,.. it does not work for me,.. all i get is a list of bcd options,. i've tried 5-6 times, but the same every time,. any ideas what has went wrong ?

[@NehalJWani]

Are you sure you are typing small 'L' in /l and not capital 'i' ?

[@dougiewatt4183]

wow,.. my bad,. I was entering number 1 ,.. all good now,.. will try and boot

[@dougiewatt4183]

All good now,.. thanks for the prompt which helped find my mistake

[@leletto100]

Works like a charm in a VmWare enviroment with windows 7 64bit. Just have to say that I had to boot with Windows 10 iso for the last part of the tutorial. The BCDBoot command in win7 enviroment is slightly different, it didn't support "/f ALL" command, and without that it didn't works. Thank you!

[@NehalJWani]

Could I do the same thing by using the menu by pressing shift+restart in the start menu, or do I haaave to make the installer media. (my download speed is like 0.5 mbps)

[@NehalJWani]

I'd recommend using another media.

[@beat461]

It can't be done with an nvme drive. gdisk is unable to read the drive. is there any other way?

[@NehalJWani]

You must be typing the command wrong. gdisk should be able to read your hard drive. Make sure you don't forget the character ':' just after the number

[@iViirTuALz]

I have a problem please help me!!! After writing "gdisk64.exe 0:" there is a message that say:"warning! main partition table overlaps the first partition by 26 blocks! Try reducing the partition table size by 104 entries. (use the "s" item on the experts" menu.)" what I have to do???

[@NehalJWani]

[@iViirTuALz]

+Nehal J Wani it appears the same thing that appears to you but above all there is the same "warning". sorry for the bad english

[@NehalJWani]

+asRayG In most cases, you can ignore the error. But you want to play safe, you can use testdisk. I can guide you how to use that. Either you follow kzbin.info/www/bejne/h5yZkH5vnbuolc0 or you send a chat request to me on hangouts and I'll help you there.

[@Gaff.]

Hi, Nehal. I notice that you're interested in helping people in the comments and I'm extremely grateful. I used your older guide and it just rendered my PC unusable. I had to use the command line from an install disc to wipe the drive and restore my system image (which I nearly didn't make; that would have been so very stupid!). So, first, is there any thing I should know about doing this with Windows 7 Home Premium 64-bit? My HDD is 3TB and when I built this PC Asus Disk Unlocker was installed to account for that, and it uses some virtual drive thing to let me use all the space, and Windows reads my HDD as 2TB and another 1TB virtual drive. I don't really understand how it works but could that be the problem? I don't care about the data on that 1TB partition/virtual drive as it's just my Steam games that can be downloaded again. I may have done one of your steps wrong as I think they're a bit vague (on your older guide at least) for those of us that don't have experience with this, but I can't be sure. Thank you again, sincerely.

[@NehalJWani]

+Ei’ríġ Proinsias Dammantaċ Ó Gamhna. Yes, you can follow this guide. If you face any difficulties, comment here or send a chat request to me on hangouts and I'll help you out.

[@Gaff.]

Nehal J Wani Thank you so very much. I'll let you know if i do or don't have any trouble. Cheers.

[@Gaff.]

Nehal J Wani I'm really really close! but I did eventually get stuck. In step 9, where you say to determine which partition has Windows, mine is now F. We're then to type bcdboot F:\Windows /l en-us /s Z: /f ALL but when I type that it doesn't tell me the boot files were created successfully; instead it gives me the whole bcdboot guide that you'd get if you'd simply typed 'bcdboot' and pressed Enter. My Windows is in Irish, and whilst I didn't think it mattered, could that be the problem? Thank you again!

[@NehalJWani]

+Ei’ríġ Proinsias Dammantaċ Ó Gamhna. Yeah, in Windows 7, I think you need to type: bcdboot F:\Windows /l en-us /s Z: /f UEFI

[@Gaff.]

Nehal J Wani Thanks very much. I tried that and several variations on it, all of which produce the same results as before. In the guide it brings up, there's a few examples of commands listed, one of which appears to copy the files. It's the first example command, and it is more or less the same as the first half of the command you're having us enter. Well, when i tried that using the correct letters for my situation, it told me it had failed to copy the files. Is that normal? I'll need to get back to it in a few hours. I don't have access to gmail because I'm using the Midori that comes with System Rescue CD and for some reason it crashes gmail. I'll attempt Hangouts when I'm back, and hopefully you'll be available. Thanks again.

[@nostraware]

Thank you very much! You are kindest internet stranger I've ever met.

+Nostradamus Alchemi Thank you for the compliment! Glad to be of help :)

[@Hrvojejur]

Hi! Tried your method twice and after completing the proces both times I ended up with a laptop that couldn't even boot up. It like it is no operating system anymore. I had to do a fresh install of Windows 10 to even get it working. Any advice on how to solve that problem?

[@NehalJWani]

You were probably booting the OS after conversion in Legacy mode. After the conversion you have to change settings in the BIOS to boot the operating system in UEFI mode or turn off Legacy Mode. If neither option is available for you, then your motherboard probably doesn't support UEFI.

[@Hrvojejur]

+Nehal J Wani It does support UEFI but here is the deal. I can't install windows on UEFI because it doesn't recognise my bootable USB. Another problem is that when installed on BIOS is has some issues, 20% of the time it won't shut down. Do you think that converting to UEFI would help? Tnx for the reply :D

[@NehalJWani]

I don't know if installing in UEFI will help in what way. But I do know that you can turn in fast startup in Windows. Also, for the USB to be bootable in UEFI mode, it has to have fat32 filesystem.

[@munsoormalik8449]

Mr. Wani, Sorry for the delay but I was trying to figure out why my system stopped booting. I finally reset CMOS, replaced the battery, unplugged everything and restarted. Eventuall, it booted up......and so did WIndows.....in UEFI mode. Sorry to have bothered you on this. It may be a good ides to warn users that if the BIOS is corrupted, like mine was, they should recover the BIOS before troubleshooting elsewhere. Alas, I also ordered a Z97 motherboard, the processor and a Noctua heat sink as I thought the motherboard was screwed. I guess every lesson has a price but I will try to return these or sell them off to someone. Thanks again, your procedure was spot on and very helpful. Munsoor Malik

[@NehalJWani]

+Munsoor Malik Well, thank you for your feedback! Much appreciated! :-)

[@peterhomonnay6846]

Thanks a lot! It works great!It was not just useful, but also fun to go through the steps. ;) I had to modify some of the commands (for example to limit the size of the UEFI partition, because I had 40 GB unallocated space in my HDD), but still you helped me a lot!

[@NehalJWani]

Thanks for the feedback! :-)

[@NehalJWani]

Thanks for the feedback! :-)

[@GregTheCamper]

I'm confused - I have two disks; one SSD which I installed windows on and one HDD (the HDD is the one that shows as having System installed in disk management). So when I go in to the SSD that has windows, I have only have 1 partition; size 238gb Offset 1024kb. When I go in to the HDD I have 1 partition; size 1862gb offset 351mb. I'm not sure which one I need to change? Any help greatly appreciated

[@NehalJWani]

+Liam Change the one in which Windows is installed.

[@GregTheCamper]

+Nehal J Wani thanks for replying. So carry on with the SSD even though there is only one partition? and do you know why the secondary HDD has an offset of 351mb? Thank you :)

[@NehalJWani]

Well, actually, you can convert both the disks to GPT partition table. The 351MB partition is probably a system partition, which you will anyway not require after converting to UEFI and creating an EFI partition. If you face any trouble, feel free to comment here.

[@GregTheCamper]

+Nehal J Wani It worked! I love you my good man. I haven't done anything to the HDD where system is installed, but the SSD with windows is now UEFI :). Thanks so much. Do you think I should change the HDD or just leave as is?

[@NehalJWani]

That is upto you. Most probably it has a MBR partition table, which restricts you to only 4 primary partitions. After that, either you convert it to a dynamic disk, or use logical partitions in an extended partition or you could just convert it to GPT partition table and forget about the number. In case you want to keep only one partition on th HDD, then it doesn't matter what partition table u choose.

Hi, i have a problem, after doping All these steps I restarted my pic and now I would get the message"reboot and select proper boot device or insert boot media in selected boot device and press a key" I tried to enable uefi in bios but I can't find that option , i only have some CSM thing that is enabled , and in that section I have three other things like pxe oprom, storage oprom and video oprom, they are all set to legacy only, if I change all of them to eufi the pic would go directly into bios settings . The secure boot is disabled , and I don't know what to do

hi, im running windows 7 64bit and i have a 2tb hard drive running on a legacy bios machine. my motherboard/bios does have the option to run uefi. i want to upgrade my hard drive to a 4tb hard drive but to do so i need it to boot in uefi so all 4tb are recognized as one drive. i want to use your tutorial to do this but when you say "without data loss" does that mean after I do this process both my windows 7 installation AND all of the programs I have installed will be available on the newly formed uefi drive so I wont have to reinstall any of the programs I had installed on my legacy drive? thank you.

[@NehalJWani]

Yes, you will have to install Windows 7 in Legacy mode and then convert it to UEFI using this method. If you have an existing installation, you can try to move it to the 4TB one, and convert that for testing it out.

[@tony00622222]

let me be more clear. i currently have a 2tb drive on my computer running windows 7 in legacy mode. i want to upgrade to a 4tb drive without having to reinstall windows or all of my installed programs. for windows to view my new 4tb drive as 1 single partition i need it to be in uefi, not legacy. so can i use your method to transfer my current 2tb drive in legacy to a new 4tb in uefi and still retain my windows installation and installed programs so that i don't have to reinstall windows or any of my programs?

[@NehalJWani]

Oh, now I understand what you mean. Yes, you can do that, and 'to copy over' I would recommend not copying each file one by one, but perform a byte by byte copy of the entire partition. Send a chat request to me on hangouts and I'll assist you there.

[@dhifaouisalim]

hi there i wanna proceed that just some noob simple questions is it working for windows 10 x86 32bit ? i saw in other forums that windows must be 64 bit i have partition D: for files,will this work for all partition that doesnt contain os ? thanks in advance.

[@NehalJWani]

+salim dhifaoui I have not tried this method for 32 bit OS.

[@dhifaouisalim]

ok but on your video there is a folder "program files (x86)" that means 32 bit, no ??

Nope, those are just 32 bit programs running inside a 64bit OS

it worked in virtualbox,i think i will go ahead and change my computer if something went wrong i will revert back to mbr in gdisk and then use windows recovery to fix boot thank you so much.

[@dhifaouisalim]

I wanna let you know thats working on virtualmachine but NOT working in real disk because windows 32 bit doesnt support GPT disk , i think you must post this so others makes attention, i tried this method and all my stuff was deleted so i had to recover my disk with easeUS partition recovery,i dont blame you its my fault

[@Thaslir]

When i try to select the gdisk64.exe it shows.usage gdisk64.exe [-1] device file. Pls help me

You need to type colon after the digit representing your hard disk. So for example if it is 0, you need to type: gdisk64.exe -l 0: Also make sure that you type the letter 'l' and not numeric '1'

[@NehalJWani]

It is -l and not -1 (small 'L' v/s numeric 'one')

Thank you. Works great. I change the command "bcdboot X:\Windows /l en-us /s Z: /f ALL" to "bcdboot X:\Windows /l de-de /s Z: /f ALL" for German

The /l argument is optional anyway. Thanks for the feedback! :-)

[@EliasNicolas07]

Why use bcdboot? Why don't use bootrec /rebuildbcd?

[@NehalJWani]

With bcdboot, I have the /f flag, which is useful if people boot in the wrong mode. So, for example if you boot the media in legacy mode but want to create entries for uefi mode, the bootrec command won't work.

[@SuperSLAMBear]

hi, whats that 200mb partition for? do i need to have this? just wondering

[@NehalJWani]

UEFI specs need an EFI partition. So yes, it is necessary

[@NehalJWani]

+Wu Jay Maybe :-)

[@munsoormalik8449]

Yes! I selected the Uefi drive where Windows installed and where I created the Efi partition.. A Windows logo shows up for 10-15 seconds then it shows a blue screen and the error: Inaccessible mobile device. If I select the same Sata port it shows some type of MBR error. When following your procedure I deleted the system reserved folder. Now the system won't post at all so will reset the cmos and reinstall Windows using a backup I made. Then, try again.

I need help the BCD command at the very end won't work, I know it's small "L". My problem is that I type the string and it doesn't do anything, it just lists the help menu for bcdboot. I'm unable to copy the BCD. I know I'm in uefi mode because system restore told me when I tried to repair and restore the system. Do you have any solutions as to why I'm command is not working? Thanks

[@NehalJWani]

If bcdboot command lists you the help menu, then you are typing something wrong. In order for me to help you, please state which version of Windows you are trying this on, and the rescue media which you are using to reach the command prompt, is of which version of Windows, and also show me the exact bcdboot command that you are typing.

[@molotovgod]

Wow. I had completely messed up my boot files and partitions fortunately, cause I don't know how how I fixed it I'm able to boot. However, I can no longer boot from the the actual drive but from bootmgr. Is this OK?

[@molotovgod]

So this is what happened, I followed your instructions to the dot and managed to convert to UEFI but when trying to copy the boot files over to using the command, nothing would happen. Turns out I had a damaged EFI and the System one that you say on your video to replace was the culprit. I ended up erasing it, recreating the EFI over the System file and it worked, all night I was freaking out because nothing would work, System restore didn't even help because it warned me that the BACKUP was Legacy and couldn't recover because I was UEFI (that's a good sign). Now, the weird part is that I can't boot directly from my 850 SSD, but I can boot from WINDOWS BOOTMGR. Is this an image? Also, I'm going to try to see if Clover see's Windows, backing up my system with the new UEFI config just in case.

[@NehalJWani]

I am glad it finally worked for you!. As far as I know, Clover does see Windows. About the boot entry, if you are able to boot from 'Windows Boot Manager", then yes, that is expected, as that is the UEFI boot entry for Windows. It's probably the case that when you try to select your SSD to boot from, your computer tries to boot it in Legacy mode. This differs from manufacturer to manufacturer. There is no harm in booting from the UEFI Boot Entry. That is how it should ideally be. Do you mind sharing the make/model of your computer?

[@molotovgod]

It's a custom built I'm writing from my phone I'll get you the specs if you still want them sometime today. I am running El Capitán on a m. 2 and windows 7 on a 850 still unable to have Clover boot windows so I gotta F12 everytime.

Recovery and Boot are in C:\ Drive as hidden folder, should I shrink the partition and then convert to GPT? (which will take a really long time) I used MBR because I used a linux distro but the last update is a mess and I got it removed My current arrangement is like this Part 1 C: [Primary] Part 2 D: (my data partition) [Logical] Part 3 (Ext4 part for linux) [Logical] Part 4: Linux swap [Logical]

[@NehalJWani]

I have stated in the video that you have to boot into windows recovery mode to type the commands to convert installation to uefi

[@NehalJWani]

An Mạnh Does your motherboard support uefi?

An Mạnh Do you have bootable media with you? Either windows recovery or installation. You just need to be able to reach command prompt
