Why won't my computer let me open my BIOS?

[siddakid]

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.

You probably have fast boot enabled, which disables all USB devices until OS initialization. What motherboard do you have?

Try F8 or F12. Your motherboard's manual should tell you the procedure to enter the BIOS.
