after a temporary disk swap, I cannot boot into an existing Qubes 4.1 installation anymore unfortunately (UEFI).
From my experience with 4.0, Qubes OS is nitpicky regarding disk device changes. What I have usually done from Live rescue mode is:
efibootmgr -v -c -u -L QubesOS -l /EFI/qubes/xen.efi -d /dev/sda -p 1
This does not work with Qubes 4.1 (“no bootable device”).
I discovered in this post a slight change in the specified bootloader:
efibootmgr -v -c -u -L QubesOS -l /EFI/qubes/grubx64.efi -d /dev/sda -p 1
1.) Is latter the proper command for Qubes OS 4.1 now?
2.) is there any information, what exactly has changed in 4.1 boot routine? For example, why the change from
grubx64.efi? (Does this have anything to do with the change from LUKSv1 to LUKSv2?)
I am no expert on UEFI and would be glad to read a bit more on this topic, preferably Qubes-specific.
Thanks in advance!
