| openSUSE 12.2/Windows 8 (UEFI) dual boot / grub2 Jan 18th 2013, 06:36 So I FINALLY got grub2 to recognize my Windows 8 install through reading various sources. I had to create a '30_windows' custom grub config because even after installing grub2 & os-prober packages patched with updated proper UEFI support I still couldn't get grub2 to recognize my Windows 8 install. I couldn't get far enough with grub2-efi (failed on locating modules). Windows 8 is installed on a separate 3 TB HDD on my desktop PC with a UEFI & Legacy (BIOS) motherboard. (UEFI & Legacy BIOS is enabled for boot devices in the BIOS). The only problem (I think), is that in the '30_windows' config file I set it to the wrong hd and/or partition before generating the grub config file with 'grub2-mkconfig -o /boot/grub2/grub.cfg' . When tyring to boot the Windows 8 entry in grub2 it says 'error: no such partition'. Can someone please help me determine what the proper config should be for my Windows 8 grub entry so I can boot to it without having to tweak my BIOS/UEFI settings every time I want to boot to Windows? Here is my info: Code:
