Has anyone else had boot issues after trying to upgrade from Windows 10 to 11? M?

Agreed. You could also try booting into safe mode and rolling back the driver for your storage controller. Another option is checking if your drive is set to RAID in BIOS and switching it to AHCI. Hope that helps.

This happened to me. After the upgrade, I got that exact black screen and had to use a recovery drive to get back to Windows 10.

Did you happen to check if your PC's storage drivers or BIOS are up to date before the upgrade?

You could also try booting into safe mode and rolling back to Windows 10 from there. Another option is to use your installation media to run startup repair. Hope that helps.

Yeah, and if you go the safe mode route, holding shift while clicking restart from the login screen can get you there even if you can't fully boot.

Agreed. That INACCESSIBLE_BOOT_DEVICE error is a key clue—have you checked if your drive's SATA mode in the BIOS is set to AHCI and not RAID?

Agreed. I had the same problem. For me, it was a conflict with an old driver from my motherboard's chipset that didn't play nice with Windows 11. Let me know if that works.

This. Yeah, that driver conflict is super common. One quick tip: try booting into safe mode and running Windows Update—sometimes it pulls a newer compatible driver automatically.
