Well my hard drive failed on my tuning computer. I bought a new hard drive thay my neighbor was going to install, but it was too late. My neighbor's looking at it to see what can be recovered. I don't have the disk to reinstall the operating system. It was an old window 7 computer. What do you guys recommend me running for a computer that's stable? Or is it worth fixing my old one? How do I go about getting and older version EFI live? I never figured out the V8 and was using v7. Sorry I'm lost with this stuff.
