To my knowledge, Windows (XP, at least; probably others) labels the boot filesystem on install, and just probes all disks every boot for a filesystem with the given label. This is why you can move a Windows disk around with relative impunity (as long as the controller drivers are installed); but simply copying all those files to another filesystem (a-la dump/restore on BSD) never results in a bootable OS, even if you put them back in the same place. This is also why booting with two attached clones of the same Windows system disk is so fun. -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net Furry Peace! - http://wwww.fur.com/peace/
