I cannot boot into Windows XP. I get as far as the screen which offers various startup options such as Safe Mode etc. It then keep going round in circles - returning to the beginning, the BIOS initiating, but never as far as Windows loading. I don't understand how this happened - the issue arise after I tried to burn a picture to CD, and the process got stuck. I think that I removed the CD prematurely. How can I get Windows to boot? It seems from using Recovery Console commands that there is no master boot record.
