I have a Predator Triton PT315-51(2019) with i5-9300H, 16GB RAM, GTX 1650, 256GB Boot Drive. I have installed “manjaro-xfce-21.2.4-minimal-220301-linux515” on a separate SSD in dual mode. So I had to change SATA Controller from Optane with RAID to AHCI(and reinstall windows). After installation of Linux, everything seems to be working fine. I can use both Windows 10 and Manjaro. But when try to access BIOS by pressing F2, it just shows a black screen with a blinking underscore on top left corner of screen. So how should I fix this?
