If you have another operating machine, you could try to bypass the initial phase of windows installation (one that requires booting from CD). What you can do is:
- disconnect the HD on your 2nd machine and connect the HD from the 1st one in it.
- start installing windows until it reboots. Before it continues installing Windows, shut down your 2nd machine and reconnect the HDs way they were before.
- now your 1st machine should continue with installation.
