BIOS is the basic input/output system that every laptop and desktop on the market comes packaged with. You normally don’t have to use it if you’ve got Windows installed. In fact, there’s little reason to need to access it in the first place. That said, it’s not something that you never need to change. The BIOS contains system settings that you might need to change on occasion. For example, the BIOS is where you change your first boot device. It’s really easy to access BIOS on your PC. When you boot into your system, you need to tap a specific key. You must tap it before you see the Windows boot logo. The only tricky part is knowing which key to tap. The key differs from system to system so we’re going to attempt to compile a list of these keys for every available PC there is.
