How to Take a Screenshot in UEFI BIOS
In UEFI bios, we can use Keyboard shortcut key F12 to Take a Screenshot and save it to a USB Flash drive.
Before you begin
UEFI Screenshot does not support USB Flash drives with NTFS format. To take a screenshot, you need to format your pen drive to the FAT32 File System.
How to do it..
Taking a screenshot is easy. First, Enter BIOS (normally you need to press F2 or Del key when your computer boots).
Then press the F12 key. When you press the F12 key, you will be asked to select the USB Flash drive.
Once you select the flash drive from the list, the screenshot will automatically be saved.
