So, I received my grandmother's HDD with Ubuntu pre-installed. I used it for awhile till I got enough money to buy Windows 10 pro. After I DBANed her HDD and installed Windows, I haven't been able to open my bios. I've spammed Delete (the original key for bios) and it won't do anything. It just loads Windows and operates normally.
