PC PROBLEM!

[Rockstar]

Ok so I installed windows 7 and worked fine then a couple of days after when I went to go on my pc it said it cannot boot insert boot device or media so I put in my vista disk and it wont let me install because the hd is not readable :S so I have managed to get into the repair options and I went to for a system restore but it wont find the main hd C: but it find another partition of 30 GB :S I can open command prompt though so can anyone help me :D

I'd just say balls to it and format that partition if you can. If it doesn't recogise it as a partiton, install windows on the remaining 30GB and play with it with a program from inside windows
