So I think this is a corrupt BIOS. You mentioned in the comments that it lost power during a factory reset… while I don’t know that this would need to interact with BIOS at all I wonder if it might have done that. As far as I’m aware there’s only two ways to fix this issue. The first would require you to hookup a BIOS programmer card to the BIOS chip on the motherboard. The second option is to buy a new BIOS chip. eBay usually has tons of these. Just make sure they match your needs. If you are comfortable with soldering and using a heat gun you can remove the old BIOS chip from the board and replace it with the new one. Of course there are some motherboards with dual BIOS and a toggle switch but this isn’t common on laptops. Since this is a budget laptop I would be pretty surprised to see it there.
