Does it give you an error message?
Yeah, the Grub Rescue came up with:
Error: No such device [instert crapload of random numbers and letters here]
I gave it a Google search and basically I had to type a few commands into the Rescue thing. Thing is that I had to type those onto my hd1,1 (Drive 1, Partition 1) but it only showed my hd0,1 and it would not apply the commands to this drive.
*Irish Accent* Have you tried turning it off and on again?
Eerhhhhyeah, multiple times even
I eventually fixed it though, but I still don't have Luna/ Elementary OS on there. Glad I can get back into the Windows install though. For those wondering, this is what I needed to do:
> Boot from Windows disc
> Format my second HDD (with Luna on it)
> Install Windows on it
> Use the bootloader from the second install to boot into the original Windows install
> Download EasyBCD
> Remove all bootloaders
> Manually add a new Windows bootloader to the C: drive
> Format second HDD (removing the extra Windows install)
So yeah, not a very good experience. Maybe it'll work better if I install them on the same drive, as the bootloader will be on the same drive as both OSs.
