Hi,

I recently installed windows 8 on a separate partition in my hard drive (the other partition had my old win7 OS, which I was looking to replace). The installation was successful and, with both win7 and win8 installed I was able to dual boot into the win 8 OS. I then proceeded to format the other partition. However, now my computer is unable to boot.

Now, I was under the impression that operating systems came with boot files, but apparently this is not so? Or perhaps there is some other issue here.

Thanks for your time and help,
Steve
