So i downloaded corel painter, tried to crack the keygen didnt work, i noticed my C drive only had 600mb of room, i cleaned the disk it said it had about 200,000kbs to free then i clicked ok, turned my head and looked back and it was a blue screen, I cant boot in any mode, i did take out my Hard Drive hooked it up to an external HD housing and can access it that way.. and i do not have a windows installation cd to boot ...any help??
