Hello!
I Followed the Gentoo handbook (OpenRC, Desktop, Signed GRUB bootloader), but it is not detected in the bios.

Why? I did everything exactly what the handbook told me to do

AFAIK UEFI BIOS doesn't "detect" GRUB, you have to set some efivar boot records to tell BIOS that GRUB is an available boot manager. That should be handled by:
Code:
grub-install

but it seems that sometimes doesn't finish the job correctly. It may be worth searching the forums for grub-install topics, though there are very many :-(
Meanwhile, it would be worth posting the output from:
Code:
efibootmgr

which should show a GRUB entry.

Okay, i'm going to post that later, right now i'm compiling a DE. I got into the system by booting into the GRUB from the Pendrive, so I know that the bootloader works atleast, it just cannot be detected by the bios
