I have a Toshiba Portege Z935 with Windows 8 pre-installed. I installed Ubuntu 12.10 with an EFI Boot Partition.

When I turn my computer on, it will boot into Grub2 and I can access both operating systems properly. If I restart the computer again it will show the Windows 8 bootloader and give me the option of booting into Windows 8 or Ubuntu.

The Windows 8 option works properly but when I try to log into Ubuntu, it gives an error pointing to the file name NSTAutoNeoGrub0.mbr and says it can't find a required file. Once I go into Windows 8 and the restart the computer, it switches to Grub2 again. In this same way every time I boot the computer it keeps alternating between Grub2 and the Windows 8 loader comes up.

I'm trying to find a way to either get Grub 2 to launch all the time, or at least get the Ubuntu entry in the Windows 8 Loader to work properly. Any help would be greatly appreciated.
