/mnt/sysimage/boot/efi/EFI/qubes/xen.cfg nor boot/efi don't exist

I’m trying to troubleshoot my problem and I’m facing issue that directories /mnt/sysimage/boot/efi/EFI/qubes/xen.cfg nor boot/efi" don’t exists although they are refered many times in documentation.

Here is ls output of my mnt directory:

install

Here is ls output of my boot folder:

initramfs-5.15.52-1.fc32.qubes.x86_64.img

I guess there is something screwed in the files and that’s the problem that Qubes doesn’t boot. How could this happen?

Problem resolved by switching to CSM mode in the BIOS settings.
