The BIOS is the place which houses the settings for your computer\’s CPU, RAM, storage and ports. In years gone by you’d be prompted during the PC boot up sequence to ‘Press F1 to Enter Setup’ or words to that effect.
Now, UEFI has replaced the BIOS on many new machines, and the route to these settings can be more convoluted. We show you how to get into the BIOS or UEFI, whether you’re using a new Windows 10 PC or an older one.
What\’s the difference between BIOS and UEFI?
BIOS (Basic Input/Output System) is the system firmware that lives on a chip in your PC. This means that it loads before the operating system and handles the basic setup of how the machine behaves.
Initially, it conducts a general check of your hardware to ensure that the RAM, hard drives, and other aspects are all alive and well, before loading the operating system itself.
Accessing the BIOS gives users the option to decide which disk is checked first for an operating system (handy if you’re fixing a system crash by booting from a USB drive), plus several other functional controls.
Which key to use differs depending on the manufacturer of your PC. So, it’s best to Google ‘bios key [insert manufacturer here]’ and see what comes up.
As with the UEFI, be careful while fiddling around with BIOS, so you don’t confuse your PC, or worse, stop it from booting up at all.
