Can't enter BIOS Asus K55A with Windows 8

[dwilson0555]

Hi, I have an Asus K55A with Windows 8 which constantly enters repair mode and hangs there when booted. I want to install Windows 10 but can't enter BIOS to change boot device using F2. Any suggestions?

Is there another F-key option to select boot drive on that same screen that gives you the option to enter the bios?

Which keybd do you have? Several gaming keybds have a switch on them to get them to work at the bios level.
