Here is the deal. I have a media center running Vista Premium box - however, my system gets beaten by Vista so I have decided to revert to XP - and I am thinking "that's easy"... guess not... what I do is this: I make sure that my DVD drive is primary boot device, and insert my bootable XP cd - when the "Press any key to boot from cd" appears, I press any key - and it seems that the system acknowledges and I can hear the cd spinning in the drive - however at some point it stops... and I am left with a blank black screen with a white cursor blinking in the top left corner. I have tried two different xp cds, but the same result - if I insert my Vista cd, I can get through the boot sequence without problems - so the dvd drive is working ok. Could there be a problem with the MBR? I have run the bootexc.exe from Vista to try and fix any errors - but that has not helped... I am stuck, I guess... any hints?
