Missing operating system windows 7

Hi, recently i've tried installing snow leopard into a partition of windows 7 ( i know, stupid). Since then i've come to the "missing operating system screen" I downloaded a free windows 7 repair disk, and it can't locate my hard disk. I'm guessing i need the drivers, but i don't know which ones i need, and where to get them

I have a toshiba satellite a205-s5814 windows 7 ultimate 32 bit. I've also tried the bootrec options, everything except (/fixboot) work. /fixboot says my volume is unrecognized or corrupted. I can still access my hard disk in the load drivers option, and can see all my original files so thats good? A clean reinstall is my last option i guess. Any help would be greatly appreciated.

EDT: now it says bootmgr is missing??? am i getting closer? at least now it recognizes i HAD windows 7
