If you use uefi :

  1. get a qubes os media installation.
  2. boot to qubes os rescue mode.
  3. skip to shell.
  4. [shell] : efibootmgr -v -c -u -L "Qubes OS" -l /EFI/qubes/grubx64.efi -d /dev/nvme0n1 -p 1
  5. reboot

change -d <which drive?> and -p <which efi partition?>.

if you want you can make sure first by issuing efibootmgr -v in dom0
