Windows 8 doesn't start after switching to CSM and I can't switvh back

[b00nwalker]

Hello everyone,

I was trying to install dual boot windows 8 and ubuntu and while attempting that i switched UEFI to CSM and now Windows doesn't start, as expected.

However now for some reason I cant access my bios anymore (i used to hold f2) so i cannot switch back to UEFI.

If i press F buttons i get to Intel Undi page where it says i have no bootable device.

At some point while i was pressing random buttons i managed to get the boot order menu but cant reproduce it. So i should somehow be able to reach bios but i dont know how..

Any help would be appreciated.
Thank you very much.

Tried a clear cmos? Can be done via jumper (read the manual) or take the battery of the motherboard for about 15min. and place it back.Take the pc of the power when doing this,so cable out of the wall socket.
