Windows Upgrade Help and more

This happened to me. I got that exact error and had to use a USB drive to roll back to Windows 10. Good luck!

This. You could also try booting from your Windows 10 install media and using the Startup Repair tool. Another option is to check if your BIOS/UEFI settings have the correct boot mode and secure boot configuration for Windows 11.

That error usually means Windows lost track of your drive during the upgrade. First, try booting into the Advanced Startup options by forcing your PC off and on three times during startup. From there, try Startup Repair. If that fails, you can try a system restore to roll back to before the upgrade, which often fixes it without losing your files.

Yeah, that's a classic sign of a botched upgrade. Try booting from your Windows 10 install media and running the startup repair tool. Let me know if that works.

Same here. Agreed, that error usually means a driver conflict. Try booting into safe mode and rolling back the display or storage drivers. Hope that helps.

Having major boot issues after trying to upgrade from Windows 10 to 11. My PC restarted, but now it just gets stuck on a black screen with a spinning circle of dots. Sometimes it flashes a quick error that says "INACCESSIBLE_BOOT_DEVICE" before restarting again. I can't get into Windows at all. Has anyone else hit this and found a way to fix it without a full wipe?

Same problem on my end. Following this thread.

I'm experiencing this too. Would love to know if anyone found a fix.

Can confirm. You could also try booting from your Windows 10 install media and using the Startup Repair tool. Another option is to check if your drive controller mode in the BIOS is set to AHCI and not RAID. Hope that helps.

Same here. I had the same problem. For me, switching the SATA mode in the BIOS back to AHCI from RAID is what finally got it to boot.
