AHCI to RAID - repair Qubes

[drtduit]

I changed the disk driver from AHCI to RAID and then again from RAID to AHCI and Qubes OS won’t boot. Obviously Ubuntu turns on without a problem, but how do I fix Qubes?

BIOS Update That Will Break Boot

If you use uefi : get a qubes os media installation. boot to qubes os rescue mode. skip to shell. [shell] : efibootmgr -v -c -u -L "Qubes OS" -l /EFI/qubes/grubx64.efi -d /dev/nvme0n1 -p 1 reboot change -d <which drive?> and -p <which efi partition?>. if you want you can make sure first by issuing efibootmgr -v in dom0
