I needed to create an account just to congratulate this oneā€¦ Very nice. I was months trying to install qubes, this was my last attemptā€¦ Now I am logged in.

THANK YOU!!!

This issue explains more about UEFI boot entries missing. There are also instructions there for fixing UEFI

  1. Mount the bootloader partition
  2. Copy the contents of /mnt/EFI/qubes/ to /mnt/EFI/BOOT/
  3. Rename grubx64.efi to bootx64.efi
  4. Rename grub.cfg to bootx64.cfg
  5. efibootmgr -v -c -u -L Qubes2 -l /EFI/BOOT/bootx64.efi -d /dev/sda -p 1

You can use such an option where you donā€™t have to copy grubx64.efi again every time after kernel update or changes in configuration files.

mount /dev/sda2 /mnt
mount /dev/sda1 /mnt/efi
cp /mnt/efi/EFI/qubes/grubx64.efi /mnt/efi/EFI/boot/bootx64.efi
efibootmgr -v -c -u -L "Default" -l /EFI/qubes/grubx64.efi -d /dev/sda -p 1
efibootmgr -v -c -u -L "Recovery" -l /EFI/boot/bootx64.efi -d /dev/sda -p 1
efibootmgr -o 0000 (instead of 0000, you must specify the number of the created boot record named Default so that it will be loaded first)
reboot

Itā€™s better to use postinst kernel hook:

@Timm Iā€™ve makred @51lieal post as the solution because a few folks pointed to it, and highlighting it seems like it could help more people finding a solution to their issues.

Of course, you asked the initial question, so please feel free to correct that if you think I made a mistake!
