Windows 11 fails to boot after update (24H2)

Anonymous

I am having this problem where as soon as my PC updated I started getting a "your computer failed to boot" page.

I was able to get past it and boot the PC correctly if I entered the boot menu and messed with the options for a bit, but the issue would always act up again the next time I tried to boot the PC. Eventually I swapped the boot order, then swapped it back, and this seemed to solve the issue, however the very next windows update broke it again and the earlier fix no longer works. I can still mess with the boot menu and access my PC, but I need to do this this literally every time I turn it on in order to use my PC.

Since I am able to access my PC, I did roll back the installed version, which resolved the issue for now (I am able to boot correctly on an earlier windows 11 version). However, that's only going to work until Microsoft forces my PC to update eventually. I want a permanent solution that won't break every time I get a Windows 11 update, or better yet a fix to the update that keeps breaking it.

Oh, this was very helpful! It looks like it was probably a BIOS issue, since immediately after updating the firmware the issue stopped happening. I've reset the PC about 4 times after that to make sure the correct boot wasn't part of the update process itself, and it boots correctly every time so far. Here's hoping it'll stay that way!

Edit:

I was wrong. I booted my PC the next day, and had the same issue again. I tried to run the commands, but the second command continued having an "access denied" issue even after disabling secure boot. How would I get around that?

Hi Amber,

Try rebuilding the Boot Configuration Data.

First, update your motherboard firmware if available. Then, open an elevated Command Prompt from Windows Recovery Environment. (Settings > System > Recovery > Advanced startup) and run the following commands in one line at a time:

bootrec /fixmbr

bootrec /fixboot (if you get an access denied error, temporarily disable Secure Boot in your firmware settings)

bootrec /scanos

bootrec /rebuildbcd

bcdboot C:\Windows /s C: /f UEFI (replace C: with the correct drive if needed)

Finally, enable Secure Boot again if you had to disable it. This process should restore the correct boot files and prevent the issue from reoccurring after updates.
