- Press the Windows key, or open the Start Menu, and type msinfo32
- Click the application that shows up - this will open your System Information.
- Once you are in the System Information application, look through the info on the right - you need to find BIOS Mode
- If your BIOS Mode is UEFI, like the image above, then everything is fine, your computer uses UEFI.
- If BIOS Mode is something else (like Legacy) then yyour computer cannot use the Endless Launcher to Restart in Endless OS. All the other features of the Endless Key should still function.
