How to Convert MBR to GPT for Free on Windows 10 without Losing Data (Easy Method)

[@andrewwhite2793]

Brilliant, worked for me. Spent hours trying to workout why my system wouldn’t reboot after changing the BIOS to UEFI, I didn’t know about the disk management side of things!

[@andrewwhite2793]

@@luis_laurent I had checked to see if my PC could upgrade to Win11 from Win10. I had to change the security settings in the BIOS,( Microsoft have a tool to se if you can upgrade the OS)however I couldn't. After researching, changing my HDD from MBR to GPT was the problem. After following the instructions in the video I went into the BIOS again and was able to change the security settings with no problem. I hope that helps you. Regards.

[@bobiktenkohoneznas5179]

same man, i hate it I can t update my win for months bcs of this hidden problem

[@MrGreenTabasco]

DUDE THANKSSSSS!!! I was ready to embark on a huuuuuuuuuuuge journey to change the system drive. Would not thought that it was possible to change the fileformat without deleting windows! THANKS MAN!

[@EmilyHillgoddessofthunder64]

Thank you so much! This was quick and easy. I was reading so many articles before I finally found this video. At first I was worried I did something wrong because I already changed the settings to UEFI only in my BIOS but then I looked again, restarted and now I have GPT.

[@bobbye4369]

Excellent video, followed these steps and was able to get my drive from MBR to GPT so I could finally update to Windows 11!

[@pictureworldphotography]

Converted my 'C' Drive to GPT following your instructions and now I see that I can upgrade to Windows 11. Thanks for the tutorial, saved me from having to take my pc into the shop to pay someone to do this for me. Awesome.

[@keithdreier4697]

It worked great for me! One machine had 2 recovery partitions that I had to remove before the mbr2gpt would run. The other worked perfectly! After struggling with the issue of not being able to boot to windows and then finding out in some MB you have to install a Graphics card and enable CMS to legacy before you can boot to windows to be able to perform the mbr2gpt. His instructions here were perfect!!!

[@jippo91]

This worked perfectly. I already had TPM2.0 and secure boot enabled, but couldnt install windows 11. I followed your guide and changed my boot option from UEFI and legacy to UEFI only and now i can install windows 11. Thank you!

[@si9ina]

Awesome!!! This is what i have been looking for. I almost plan to paid for miniTool to convert my OS to GPT. With your guide, now my gaming PC is ready for windows 11. You are the best. 🥳

[@darrenmillward4445]

You just turned me into a computer wizz kid.. my family think I'm a genius but we both know it was your tuition that made me this way.. kind regards and thank you for the easy to follow video.. yes I'm 53 and I refer to all film and movie clips as video😂

[@Paradoxical_03]

HUGE HELP. I didn’t wanna have to backup everything and reinstall windows. This saved so much time thank you !

[@ArmadilloManiac]

My God, by far the easiest way to do this. Great video. Expertly explained. No need to download other windows apps like some videos told me to do. Thanks for this!

[@Slackersink1]

Thank you for the smooth walkthrough, this worked quick and easy. Now to upgrade to Win11 and hope that doesn't blow anything up!

[@paullee6256]

Thank you. Very useful and to the point. Shame I wasted so much time on others that were either hidden product promotions or just plain incorrect.

[@pliniosanick8531]

I can't thank you enough, after searching a lot, It really worked. I just liked your video and subscribed. Thanks a lot mate!

[@joshevans3587]

This is the most clear, easy to follow video i have found to do this. Big thumbs up!

[@laguitarrabelyakov]

Thank you sooo much, was trying to get Resizable Bar working on my machine, worked perfectly!

[@Kuzeち]

Thank you very much dude🤣 other's video said we should delete partition and in my situation i need to install new os and bla bla. You did a good job💪

[@Vlainstrike]

Thank you! This came in handy when trying to clone an old 1TB MBR HDD onto a 4TB SSD. I found out the hard way that trying to clone a MBR drive without first converting to GPT results in an unbootable clone drive.

[@radibuns2460]

Thank you!! It worked perfectly and saved me from almost buying a partition manager assistant for $40... cheers!

Now i can sleep finally, thanks to you sir!

[@theoschela]

Wow, you totally de-mystified this process - thank-you!

[@MyAirMyles]

This is legit. Thanks for the easy, to the point, video.

[@swiftoatmeal1874]

This video acutally worked thank God Almighty I have been trying to do this for a whole day after reinstalling CPU and then system couldnt boot so I had to switch to CSM and then found out GPT would work for the UEFI mode and this video solved it all thank you

[@ObiMatt87]

Outstanding video. Super-easy to follow your directions and greatly appreciated the help. Worked perfectly! Thank you.

[@xxexixx]

This is a brilliant tutorial on how to convert. Your work is amazing. Keep it up.

[@naimatakku]

Thank you. Worked great for me! Just make sure you are familiar with the BIOS settings. Took me couple of tries to boot windows

[@06Satorare]

Yes. Finall get all tick to meet Windows 11 requirments. This is life saver for me. Thanks 👍👍👍i have just subscribed your channel.

[@jsbv7245]

I already had the changes in the BIOS so when i restart my pc it worked just fine. Thanks

[@tina-hw3ut]

Life saver this fixed my issue with meeting the requirements for windows 11 upgrade since secure boot wouldn't work as I had legacy boot configuration

[@MeLtDeDoWn]

Thank you for the clear instructions - saved me a boat load of time!

[@exrtiic]

still works today 12/20/2024 what an amazing tutorial thank you for your help!

[@paulawinpanggodsway2720]

this won't work in cases where windows wasn't install with the uefi boot option the tutorial is not clear and if you have valuable information on your PC you should be careful

[@REDLANTERNCORPS4]

For me it worked fine. I had a Legacy bios. Of course any data you care about should always be backed up, and also: it's good to watch multiple tutorials before you make the decision. The legacy to UEFI bios change happens after you convert the disk not before. (Right?)

[@KingsPS_Gaming]

Its working thanks alot bro❤

[@bryandiel6773]

I had offline cloned an SSD from a HDD, had unallocated space in my boot drive, and it shows up as MBR in disk management, I moved data files from boot drive to data drive, reset default new storage to data drive, only have OS, reserved and recovery and apps/games on boot drive, did a recovery backup, and cloned my boot drive to a spare ssd....used Aomei partion assistant to merge the free unallocated space to (C) partition then apply. Then I followed the steps on this video to switch OS drive from MBR to GPT..switched the bios on my new Ryzen build to UEFI...worked. Boots much quicker w/o having to use fast boot. I will need to do the same to my sons PC before I can clone his new NVME drive.

[@TheB00Man]

Dude! Thanks so much for posting this. You are a light unto the world.

[@dubrpanda1636]

THANKYOU!!!!!!! im late but this worked!! After months of searching and trying things

[@MrTredd222]

Thanks! I followed it to the "T" and it was very useful. I ended up having to shrink my SSD down to about 200MB in the disk partition due to the validation step not working and it worked flawlessly afterward...

[@markcook4043]

Nice one sir I wanted to keep my pc beyond 2025 so this only helped me thank you so much.

[@analogGhost]

This video saved my pc, thank you very much friend.

[@donjuan7428]

This works and is easy and free. Thank you.

[@larrymorgan2811]

This worked perfectly for me. Thank you.

[@heinekkenihd1532]

Thank you so much!! This worked for me and I finally got windows 11 installed 👍 I booted my pc trough M.2 SSD and when I enabled the secure boot in bios it wouldn't start the windows. So the partition type was the reason!.

[@brandonden795]

Same, I crapped my pants

[@soliver111]

Thanks for the information. I have two older PCs that the BIOS did not have the option. One booted fine the other failed to boot. I was able to recover the failed PC with full disk image restore.

[@jippo91]

By the way. The UEFI boot option in the newer asus motherboards can be found in BIOS-> Boot-> CSM (Compatibility Support Module)-> Boot Device Control. I have a asus rog strix B450f gaming motherboard and there is where i found my UEFI options.

[@MuhammedUsmanKhanofficial]

Thanks for this knowledge man i love to appreciate your efforts ❤❤❤❤

[@nexuqk]

thank you,i needed this to enable Amd SAM

[@frich2k]

Huge thumbs up man! Thank you for clarifying and telling how to do the steps. Now if only I understood what actually changed here xD I feel like unless you are an absolute tech savy, you are just doing what needs to be done, but overall I'm being clueless what this gpt partition style differs from mbr xd

[@0Erag0n]

Short answer is Old vs New filesystem. You can have 2tb partitions on Mbr but 9,8ZB (9.8 billion TB) on gpt. 4patitions mbr 128partitions gpt. Mbr bIos vs Gpt UEFI.

[@chavito808]

This really helped a lot! Thanks!

[@minakhoshaba8109]

if you are getting stuck on " trying to shrink the OS partition," then here is what you should do. Close command prompt Right-click on " my pc" and select properties(This will open the " about" settings tab) Next,click on "system protection" under related settings ( down below or to the right of the page) it will show that you have system protection turned on on disk 0 Click on that drive, then "configure", then disable system protection" No go back and retry the video method. Even with this my command prompt was trying to shrink for about 5 seconds before it finished

[@robn8556]

short , sweet and simple . thank you. very helpful video..👌

[@Chris-Workshop]

excellent! worked like a charm! thanks!

[@GilbertCuizon]

thank you sir! its really work! i can use now the windows 11

[@KNarllDrool]

😃😍🤩 Thank you very much I appreciate a good Command line tech teacher , I too wasted time watching how to hatchet my OS when all I had to do was buy the module for my gigabyte MoBo and then take a lesson from the Master 🍾😁

[@ingeborgdot]

I can't get my disk to validate like it shows. I've done this on other PCs and it worked like a charm. This one is not so easy. It says it can't find the OS. Well, I'm in the OS, what is wrong?

[@robolivieri9915]

Thanks a lot dude it worked !

[@N4CHO_]

Thank you for this video! liked and subbed.

[@sabbathian]

Worked great, thank you!

[@PhatBoyiee]

when i typed mbr2gpt /validate /disk:4 /allowFullOS it gave me an error disk sector size is: 512 bytes? I had to go to computer management and shrink the C drive by 51200 then ran the validate process again and it worked.

[@misfitdad4073]

did you have to go in and disable restore or kernal before shrinking?

[@eljjtp]

I've been at this all night and it still says cannot find room for the EFI system partition. Its a brand new 18tb drive and I copied my 256 boot drive to it. MS and windows just suck. I give up.

[@land.1368]

PERFECT! love you

[@lous1882]

What to do about converting the other physical drives was never mentioned. Since it wasn't addressed, the presumption is that nothing needs to be done. Besides the OS disk, I have 2 other physical drives controlled by Windows Storage Spaces.

[@TOGthatoneguy]

this helped a lot thanks man.

[@MissyKebz]

you've helped me so much. Thank you 🙏🏼dropping a sub 😊

This was awesome!

[@back2basics512]

bro thanks this worked great for me without software and if you can make a video on how to change the manufacturer boot up logo as well please

[@REDLANTERNCORPS4]

You can also go into disk management before you restart the machine to make sure it says GPT disk

One of the reasons could be that your disk is split in more than 3, I had 4 partitions and after I unified two of them it worked fine

Same here..

- "Disk layout validation failed for disk 0." -> C:\Windows\setuperr.log -> "Too many MBR partitions found, no room to create EFI system partition." - MBR2GPT tool does not support more than three (3) partitions in the MBR partition table, and you should not have any extended/logical partition. All three partitions must be primary partitions.
