The computer is a friend's Advent DHE X22 running Windows XP Media Center\nEdition 2006. The PC is caught in a never ending restart loop.\n\nAt switch on the computer confirms that it could not start up properly at\nthe last attempt to boot - with the usual screen suggesting that I can\nstart in 'Safe Mode', 'Safe Mode with Networking' etc. My intention was to\nboot into safe mode and disable automatic restarts to try to troubleshoot\nthe problem. But selecting any of the options available from 'Safe Mode' to\n'Start Windows Normally' simply repeats the cycle of restarts.\n\nThe only Windows disk available at the moment (until he finds his recovery\ndisk) is my own standard Windows XP Home SP2 disk. When I turned on the\ncomputer with the Windows Home disk inserted, I was able to start the "boot\nfrom CD" process, progressing to the stage at which it asks whether I would\nlike to re-install Windows etc. At this stage the computer does not reboot\nitself, indicating (I think) that the problem is not hardware related, but\nprobably driver or registry related.\n\nI stopped at that point as I'm not sure of the consequences in trying the\nWindows Home 'repair install' routine on a Media Centre PC. Is there any way\nI can get the computer to start in Safe Mode so that I can at least start\nthe trouble-shooting process without a Windows Media Center Disk or the\noriginal recovery disk?
