How to access the BIOS or UEFI in Windows 10

Quick note: BIOS and UEFI are not the same things but we can refer to the UEFI as the newer version of BIOS since this is its replacement and you will do everything you would have normally done through the BIOS in the UEFI.

There are multiple reasons why you might want to access the BIOS or UEFI, enabling, disabling or changing settings, installing new hardware, perform updates etc..

You may also want to enable virtualization to run a virtual machine which is something I discussed in my previous posts.

How to access the UEFI or BIOS

There are two ways to access the Bios or UEFI, using some short-key at bootup, or using the Windows Start menu.

Technically there is a third way to access the Bios, and that I automatic when you boot up a machine without an operating system installed.

Enter the Bios or UEFI Using a Short-key or key combination during Boot-up

We will first want to reboot your computer or laptop from Windows > Power > Restart

Once the screen goes black you will need to hold down one of the function key.

Unfortunately, the Key to hold down depends on the Maker of your Laptop or the Motherboard of your PC, but the most common function key is F2 which works with Dell, Lenovo, Toshiba, Asus, Acer for some other maker it could be DEL (delete key), F1, ESC etc. On Microsoft Surface Tablets you need to hold down the Up volume button.

You may want to search the model of your laptop or Motherboard if non of the above works alternatively you can use the Windows 10 Start menu from the settings.
