PXE Disabled - Black screen

[roulette]

I have a problem and to explain it short,

Yesterday when I started my Asus laptop I got the message "pxe-e61 media test failure" and it just restarted. Couldn't get out of it so I went to bios and disabled PXE-boot something on Boot options.
This I should've never have done because now when I start the computer it's just a black screen and it wont respond to anything.

Does anyone know how do fix it? Reset bios and if so, how?

Try taking cmos battery. Leave it out for about a min. This should reset the bios for. Then allow you to boot the computer.

Could be a failed hard drive
