Well, I think it is obvious from the screen shot, but your HD is erroring out. Does it work properly in the bios? Is there a HD test option in the Bios? If either of those are a yes, or both, check them out. Have the Bios do a HD test, and see what it says about it. If all is fine, then your vista install is shot, and I hope you we're smart enough to install your PC with 2 partitions, 1 for windows and 1 for programs/important data. If not, you might be screwed getting any of your stuff back. Might try finding a local PC store that specializes in PC data retrieval, and then if possible, re-install vista. If HD is shot, well, then your kind of at a loss there either way, and I'm sure you know what to do there. Note: these aren't definate answers, just answers from many past experiences working on pcs with this same sort of error.
