Can't boot on Qubes (PXE-E61)

Right now I’m trying something from the documentation page called UEFI troubleshooting… but I don’t know where to start.

My problem is that, after entering the rescue shell, choosing option 1 and typing my passphrase, nothing is mounted. I’m not sure where I can get /boot. I can mount /dev/sda1 and /dev/sda2:

• sda1 contains a unique directory: EFI/
• sda2 contains several files and a efi/ directory

So, maybe the content of sda1 is what is mounted under /boot/efi/ ? I tried the procedure Installation finished but “Qubes” boot option is missing and xen.cfg is empty / Installation fails with “failed to set new efi boot target” in the previously mentionned page but after selecting the Qubes option in Boot menu, I go back to this same menu, nothing happens.

This guide is outdated and works only for Qubes OS 4.0.
The up to date UEFI fix is this one:

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
