Hello everyone,
I installed Qubes OS 4.1 successfully in UEFI mode. After restart Qubes OS did not boot so I moved to BIOS UEFI Boot Selection. There I am able to choose one of the following files in the directory named “qubes”. Other directories which are available are named “BOOT” and “fedora” but they do not include a selectable file).
- xen.efi
- grubx64.efi
- xen-4.14.3.efi
- grub.cfg
Only when choosing grubx64.efi system is able to start Qubes OS.
Could you please confirm that I have not made any mistakes regarding the manual selection, which could affect security?
Thank you.

I want to add that if I install in the Legacy mode of the system, I have not to make any changes after Qubes installation and reboot to boot correctly.
Further explanation: Righ before selecting which device to boot from, you can choose UEFI or Legacy mode. USB device is listed in both sections. I am aware that “Legacy” is also a mode of UEFI according to What's the best: UEFI vs. Legacy? (security-wise) - #4 by Fire
maybe your uefi entry is overwritten, have you check with running efibootmgr via qubes rescue / other os / if you have successfully booted to dom0?
yes nothing wrong.
Thank you for your answer. It seems that you are right, but I did not change it right after installation and manually set the UEFI entry.
