I also looked at:
qubes-os[dot][org]/doc/uefi-troubleshooting/#installation-finished-but-qubes-boot-option-is-missing-and-xencfg-is-empty–installation-fails-with-failed-to-set-new-efi-boot-target

step 2.

cd /mnt/sysimage/boot/efi/EFI/qubes
cp xen-*.efi xen.efi

Copy them where to?

Step 3. Create xen.cfg
An aditinal tip would be:
tocuh xen.cfg
nano notwor for me to edt, so I used:
vi xen.cfg

It’s outdated.
To fix missing UEFI entry you need to do this:

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

Also the Qubes OS 4.2 is released so it’s better to install it instead of Qubes OS 4.1.2.
