How to Fix No Bootable Device Not Found

How to Fix No Bootable Device Not Found
Today we will take a look at how to troubleshoot and fix no bootable device found. There are many reasons for boot device not found and we will do step by step to diagnose no bootable device.
1. Remove any USB devices apart from Mouse and Keyboard
2. Check system date and time
3. Check CMOS battery and replace it if needed.
4. Is the drive visible in BIOS?
5. Change setting to UEFI or CSM Or Legacy
6. Disable Secure Boot
7. Reseat M.2 Drive or check cables on Hard Drive and SSD, also unplug them and plug them back or change connector
8. Reinstall Windows, I know it’s a pain, but it could be a windows problem.
9. Check to see if drive is bad. CrystalDiskInfo and Western Digital Data Lifeguard Tools can be used to check drive, if bad sectors or errors, replace drive.

Thank you fixed the problem immediately was worried I had corrupted files but this sorted it straight away cheers mate

Yeah that was simple, glad to have clarification though. Tech and security is moving so fast it gets a little overwhelming, Got a like and sub from me..many thanks

[@ThatGUY666666]

Just finished installing a new motherboard and CPU. Just about had a heart attack when I got this message. Your video helped me knock it right out. My blood pressure and I thank you from the bottom of my heart.

[@RTXEddy]

I still keep getting routed to BIOS 😩

[@brandankeel1855]

I upgraded my graphics card however when I turned the PC on I got stuck on the BIOS screen with no bootable drive found even though the system was reading my hard drives. Spent an hour reviewing half dozen videos with no luck. I then changed my search terms and watched your video. My CSM was disabled; after enabling it I was able to boot into Windows. Thank you! Your video was easy to understand and saved me a trip to the local PC repair shop. Thanks again and Happy New Year!

[@antoniogalang4260]

Yup! Same issue. Cleaned my PC and took out all the components in the process. Put it all back together in the original way I had it and then ran into this issue. CSM fix like the previous comment says is how I fixed it.

[@ShiroganeABA]

Same here 😂

[@DaveHoS]

had the issue of no drives showing up, set csm support to legacy and instantly works again. would have never figured this out on my own you saved me so much time and worry, Great vid!

[@bimgus7319]

Thanks man! Helped me too

[@asapgetwitit]

I didn’t even have to watch the video this comment saved my entire existence

[@PoliceCrimess]

Did u change the boot the boot mode too?

[@PoliceCrimess]

To legacy? Or did you leave boot mode on uefi, and then just change the csm support?

[@ps1laracroft989]

WTF You helped me! thanks man labya

[@peternedermann6751]

Like some of the comments mentioned already: if you are trying to breathe life into your PC after changing the Motherboard and CPU, most likely none of thesteps mentioned in the video will help: you will need to reinstall windows. It is really frustrating (instead of just buying another key and keeping your settings, you need to reinstall the whole 9 yards), but that is apparently how things now work. Just my experience.

[@seanwilson-ross8073]

CSM is for legacy hardware

None of this worked for me and all it keeps doing is going to straight back to bios should I try a windows recovery usb

2 hrs later and still helping people out! Thank you kindly for all the information!

[@avejst]

Great video as always. In my last install at an new mother board, my old SSD would not boot up. I had to clean the SSD, and then install win10 again. And now it works. Normally win 10 makes two drives at a fresh install, but now it was 3 drives! But now it works. Strange with this chance. Thanks for sharing your experience with all of us 👍😀

[@eijosmanc]

Mate, thank you for this video. I thought I'd tried every single thing. Thanks to your vid I finally unplugged all USB-devices as a last resort before giving up - AND IT WORKED!

[@adnelortiz]

I had such problem with an SSD I put on my daughter's PC, after checking everything I could, the fix was to wiggle the SATA wires a bit, and those have the click mechanism so they were properly connected. Not sure if the wire is faulty but after doing it, all worked fine. Have seen the same thing in a few machines, seems like poor contact.

[@eliotmace2702]

My guy you're a life saver, would never think to change the CSM. Keep up the good work!

[@kihoseo2254]

I was much embarrassed and confused when I turned on a new computer. You saved me! Much appreciated!

[@RockEdison]

Helped me out, thanks much! Funny thing is that it booted flawelessly until i changed the chip fan, then didn't want to recognize the NVME as a boot disk. My guess is that enabling CSM did the trick but could also have been setting the windows OS in boot settings.

[@mushroomhigh24]

Hell yeah thanks! finally got into my new pc, always have a problem with windows not being found when I switch everything to a new rig but always end up getting through. Wouldn’t have done it again without this video

[@WuHendrix]

Actually, before doing all of that in the video, first thing to do is make sure all your cables are connected properly! Been looking for hours trying to find a fix and it was just the cable to the ssd that was a tiny bit unplugged.

[@bloom2726]

Thank you so much 😮‍💨 I was getting worried and all it took was 4 minutes of video time. You’re a hero lol

[@carsonm7292]

Thanks, I reset my CMOS as part of unrelated troubleshooting and forgot all about re-enabling CSM afterwards. Never would have figured it out on my own. Great video, clear explanations.

Three years later, after a motherboard replacement, "No Bootable Device Found". Following this video, I got me some Windows back, baby.! I'm running Window 10, and in the BIOS, ADVANCED, BOOT section, CMS support was disabled. Enabling allowed my boot drive to be recognized and boot. 😘

Thanks for the tips. Lifesaver. After turning on Rapid Storage by mistake, my Asus motherboard couldn't find bootable drives anymore. Changing the CSM settings worked for me.

I have same problem! My PC is new build I don’t have any OS yet, I want to boot from my windows USS I bought from Microsoft. But when I enable CSM the pc reboots but then I get screen signal lost. No graphic signal what’s so evet. Please help!

Thank you for positing. I spent 6 hours digging around and this video had information that helped me find a solution.

[@nicolew4376]

Thank you! My pc was working perfectly well until I installed an nvme ssd then suddenly it stopped recognising my ssd and hdd. Enabling CSM and Legacy for storage drives solved it.

[@lyfandeth]

I've seen Win10 upgrades result in the same error. MS tech support can fix that, but there is 3rd party software that will restore the boot information & fix it in minutes. Apparently Win10 corrupts or mis-sets the boot options in some cases.

[@noobesemipro3081]

Thanks so much, had hours of trying to figure out bios, and yours is the one that worked.

[@istizwick418]

Yes thank you!!! The change to UEFI from legacy solved it!✅ Thank you so much!

[@SurfCityDurban]

Good video for less IT savvy folks. I've found that most times it's not usually the BIOS that is the issue, but you can't eliminate it as it does happen. Rebuilding the BCD with diskpart usually fixes the problem unless there is a hardware fault with the disk.

[@dixienormes-xl2is]

What steps did you take? The furthest I’ve gotten with no luck yet is I can only boot into windows recovery and bios at most but no boot options. Ran bootrec /rebuildbcd and fix mbr commands but can’t run the bootrec fix boot command access is denied

[@Insoo_1]

Hi i Did what you said but after i save and restart my PC always shutdowns itself and goes back to zero. Any ideas? Been fixing my pc for hours.

[@womsirom]

A-mazing…it was CSM support for me. PC shut down and would not even boot up. The power button on the Z690 board would not even work. Overnight the power was left off. Thankfully it got into bios and then the CSM toggle gifted me Windows back. Thanks mate :)

Thank you! I had reset my BIOS via a pin short during some PSU troubleshooting, and was stumped why it would not see devices as bootable after that. CSM enable did the trick!

CSM did it for me. I didn't even realize that was a thing. It would be nice if the BIOS contained a quick explanation for what each of these things actually are.

[@lukis4438]

Thank you, the CMS switch helped, after that when loading into windows, i pressed F11 and it got me into boot setup, in there there was a wrong drive selected, so I switched to my boot drive and it works now

[@dongmong7215]

I had this exact problem, but non of the suggested fixes worked for me. Well, there was one option left and that was to reinstall windows 10. But before I would do that I thought about reinstalling my bios version. That fixed it! So if nothing works of the suggested fixes in this fine video then reinstall the bios or update it if a new version is out. At least it worked for me and am I happy af it did, because I used hours trying to fix this problem. The catalyst for the problem was me setting resizable bar up in bios. That gave me the black screen doing boot up. But because I forgot to disable fast boot in bios or in Win 10 software I could not get in to Win 10 or in to bios. So I cleared CMOS and then my problems started. Cheers

[@kirito4939]

For me it was the Webcam. I unplugged it because didnt need it. And it booted. Detected the storage device but didnt show me a boot option on my SSD. Great vid👍🏻

[@tekharthazenyatta2310]

Another happy viewer here whose "no bootable devices found" error was resolved by CSM (compatibility support module) and enabling legacy boot. Although this solved the problem, I wasn't at all satisfied with the solution. I have a new motherboard (LGA 1700 chipset, DDR5 RAM, etc) as of February 2023. Why would I have to do "legacy" anything, I wondered? I eventually discovered the true root of the problem. I had one bootable drive with Windows 10 from a previous computer, a drive that could only be recognized in legacy mode (Windows 10 qualifies as "legacy," I again wondered?). It turns out that newer UEFI boot security protocols, which are required to install Windows 11, reject drives with Windows pre-installed on it. Presumably, my older Windows drive didn't have AHCI/UEFI activated during the installation, hence the rejection. When I used the new PC to install Windows 11 on a different drive, I was then able to return to UEFI and secure boot. Part of the "legacy mode" is to accommodate drives that had Windows pre-installed without UEFI.

[@arturlisetschko1089]

Couldn´t boot anymore after a bios update but turning csm on did the trick. Much appreciated!

For me, unplugging all my USB's (All of them keyboard and mouse) worked. Still whenever I update windows it boots back to BIOS and I have to unplug everything again to get it to boot. I'm wondering why it's having such a hard time seeing my drive as a bootable device. Like you, BIOS detects the drive no problem- it just doesn't register as a bootable device.

Currently running Windows repair, got it past the boot screen after trying CSM
