As far as I can see/read, the problem here is an un-bootable system, not a 'dead' hard drive.

It's one thing to have a corrupt system partition that end up making the system unable to boot and it's an entirely different thing to have a completely -and definitively- dead hard drive.

Thus you have to first rule out the first option before jumping to replace the hard drive... and I hope you know how to fix a corrupt system partition.

No, I have tested with another hard drive and Windows has run perfectly without any problems. The problem is not the computer or boot. Please read the topic thoroughly first and then comment. Thank you
