all im doing now is using my boot disk to startup the command prompt. so far i tried scanreg /all and scandisk /all. And the problem seems to be drive C:, since everytie i try to access it, prompt tells me "invalid media type reading drive C:" ANY other things i can try. it'll be much appreciated. i forgot to add that this all started because windows said it ran out of space on drive c: then it froze up so i had to shut down manually. any ways on how to delete some files to get some free space?
