I have installed Ubuntu 12.10 onto my Windows 8 UEFI HP Pavilion g6 laptop. I installed ubuntu by clicking 'something else' in the installation window. I then made 4 partitions: /boot , / , /home and a swap partition. It installed without a hitch, and it booted straight into Windows 8. Because I knew Windows 8 wouldn't find Ubuntu, I used EasyBCD to add the OS to the boot list. When I boot, it comes up with the boot manager, showing Windows 8 and Ubuntu. I can boot into 8 perfectly fine, but when I try to boot into Ubuntu it comes up with a 0xc000007c error saying that /NST/AutoNeoGrub0.mbr is missing or corrupt. It's definitely in there, as I have checked. Also I have already run the recommended fix on Boot Repair using the live CD. Could somebody please help me out with this? I'm getting nowhere. Thanks in advance
EasyBCD doesn't work with UEFI. Refer to their FAQ.
Does EasyBCD have EFI support? No, not yet.
