How do I recover my UEFI? I can't boot!

Okay guys,

I did something stupid. But first the back story. 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 net. As a last ditch effort, I very stupidly 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

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.

Any help would be appreciated.

I did the same thing with the same laptop yesterday. I posted a thread at notebook review in the asus section as well as at rog.asus.com in the non-rog laptop section. no replies yet. Of course i can boot in legacy mode but i cant boot in UEFI, all boot options have been deleted. If i find the fix i'll let you know. Please do the same for me if you find the fix. Good luck

I came across your posts after causing a similar problem with my ASUS X55A, and just after, I found a forum where someone did something similar to a Dell that helped me fix my problem here. After that last post, I thought I'd share my findings. Basically, you can disable the UEFI, and enable the legacy Boot Configuration (PXE OpROM), and that will let the BIOS do the work of finding your bootable disks and partitions, and let you get back to work on them. You can re-enable UEFI afterwards if you'd like; the new boot configurations/paths/priorities will remain. I hope that helps.

Just remember to leave the BIOS with whichever setting you'll stick with before making any other changes. Windows uses two different kinds of partitioning for each of UEFI and Legacy BIOS, and it will get mad if you have Windows installed with UEFI and change to legacy permanently, and Vice-Versa.
