dual boot – UEFI selected as primary option in GRUB customizer

I’ve installed Fedora in my windows machine a while ago for dual boot (I’m new at this) and last month, when trying to get rid of a problem by my own, I set UEFI settings as the primary boot option in GRUB customizer and I’m not being able to start my linux since. When trying to start with Fedora I’m stuck in the loop: BIOS, restart, BIOS, restart…
I coudn’t find any solutions to this specific situation online and as said, I’m new to this. Does someone has any idea on how to solve this?
