Drive no more bootable

Before I took the SSD out, it was working. Now it is no longer bootable.

Can someone maybe tell me what the problem is or help me out with an workaround?

Best regards


This does not look like a Qubes-specific problem, since the bootloader comes from Fedora. Perhaps you may have a better luck by asking on their forums. Also, you can try Qubes restore mode by booting the Qubes usb stick.

I get that error when I installed the OS in uefi and switched the bios to load in legacy.

Perhaps this can help: No boot screen for installation

I already have installed qubes on that drive and it ran until i disconnected the drive and connected it later. Also it displays no GRUB-Bootloader, because it seems that it was installed in UEFI-Mode.

Take a look at

Something like

efibootmgr -v -c -L QubesOS -l /EFI/qubes/xen.efi -d /dev/xxx

should do the trick, where xxx is the primary partition of main disk containing the GPT table. E.g. /dev/sda1.

-d ( /dev/sda or /dev/sdb or /dev/sdc, where you store the /EFI/qubes/xen.efi ) then add -p ( 1 or 2 or 3, which partition )
