Windows 7: having trouble installing windows 7 ultimate on a desktop that had XP

having trouble installing windows 7 ultimate on a desktop that had XP

I have HP Compaq dc7700 small form factor desktop that has been running on XP. I wanted to install windows 7 ultimate and the installation started well until the point where windows starts loading services. unfortunately there was a blackout and on resuming the installation, the computer boots from the hard drive but installation is not completed. The computer started displaying this message: "The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install windows click "OK" to restart the computer and restart the installation." I have restarted the computer but every time it loads the incomplete installation and displays the error. I have attempted to select disc drive and usb as the first boot device but each time the computer boots from the hard disk and displays this error. Any ideas on how to sort this out will be appreciated.
I have also tried booting with a different disc but nothing seems to be working
