I have a Lenovo Edge 15, of which I installed Ubuntu on (removed Windows).
I have to access the BIOS. However, the F12 key won't open it, and the Lenovo logo won't even display. Instead, it goes directly to Ubuntu asking me for my password to decrypt the system.
I need help accessing BIOS
EDIT: It seems the BIOS itself maybe messed up. When I press F2, I get a black screen, and it stays there until reboot
