Installing windows

[Guest]

My hard drive crashed so I went out and bought a new one. I'm trying to install windows on it. It starts loading and with both vista and xp it doesn't finish and I get an error. With xp the error is "stop:c0000221 unknown hard error \systemroot\system32\ntdll.dll" and with vista it says something like make sure that all installation files are included with disk. I don't have any driver disks (my fiances comp, she didnt back anything up) and the computer is home built so there is no actual windows recovery disk. What am I doing wrong?

Try using the manufacturer's hard drive utility.

If you have 2 optical drives, try the other one.
