Only happens sometimes,maybe bad connection or hard drive failing.Maybe a good time to make backups
I try to boot up my pc and it gives me a msg operating system not found. If I restart the pc a couple of times it finally boots up. I've been in the bios and under hard drive it says none (sometimes). I've changed it to user instead of auto. I have also changed the cable. Same resuts. Any suggestions on what could be causing this to happen?
