If sounds like boot file failures. Most of the time even if the drive can’t be repaired you can still recover the data. I got an adapter to run a hard drive on a USB port for about $35. It doesn’t have a cover because it is designed for repair work. It is good for both ide and sata drives.
Do you have any DVD’s that have the SO files? If so the easiest repair would be to replace the old hard drive and new build. And then recover data from old drive.
What's the name and brand of that? I could use one.
