EFI boot entry disappeared pt. 2

I wonder if your issue is similar to this one, a CMOS battery issue?

I get “Boot Fail” every time after installing EOS BSPWM (solved)

I installed EOS BSPWM. After rebooting the laptop, BIOS enabled safe boot and when I turn it off after PC reboot safe boot turns on again. Because of this, I cannot enter OS (BIOS “Boot Fail” message) and cannot even start EOS live USB. I just stuck in BIOS and CAN’T do anything. What should I do? When I installed EOS Gnome, KDE and i3wm multiple timesthere was no such problem.
