Cannot access BIOS after EndeavourOS installation

uint64

Hi!

So I recently installed EndeavourOS. However, after a reboot (the installation was complete), I was booted into GNU GRUB terminal. I didn't know what happened, and couldn't boot into the OS anyway. Also, when I tried booting through the USB, it said "Security Boot Fail", although I had Secure Boot disabled. I was confused. I didn't know what to do. I came up with the idea of changing the option through BIOS - that's when I got even more scared. I couldn't enter BIOS, because when I hold F2 when it was booting, the screen was cleared, and a white, frozen underline appeared. Although I waited about 2 minutes, nothing appeared. The F12 key works and it shows the available boot options. I have Windows 10 installed now, which luckily doesn't require Secure Boot disabled. Any ideas? I tried installing the newest BIOS update, which I thought will fix anything, but apparently I have the latest version , and the application just quits.

Please help!

Yeah, a few of those custom Linux distributions disable the timeout for the keypress to enter the BIOS. All you can do is hold the key down and hope you get in during the zero seconds allowed.
