I installed Ubuntu 13.04 on my Win 8 Pre-loaded system as dual boot. At this point I could no longer boot Windows 8. I tried using boot-repair, but it did not work. I have basically tried everything I could think of or get off the internet. As a last ditch effort, I tried deleting all the boot options in UEFI in hopes that it would force UEFI to scan the disks. Now UEFI will not load. When I turn on my system, I see that it tries to read the CD drive, but I get no display. I also tried to hold F9 at boot as recomended by ASUS. No-go.
The last option that I could come up with is to put the disk in another computer and copy the UEFI files from the recovery partition to the UEFI partition, and THEN try booting
EDIT: I have also tried removing the laptop battery and holding CTRL+HOME and pressing power with both USB and CD containing the BIOS/UEFI re-named N76VJ.BIN in both root folder and EFI/ASUS/ This caused the HDD light to light and the keyboard took longer to light up so I'm assuming it did something, however this still did not fix the problem.
