[Shadow of Chaos]

Well... Ive been looking around, and so far this is the closest thing ive found anywhere to my system... so Ill try giving it a shot.

I recently got one of those XPS's and they have this new OS called "Media Center" which is supposed to be similar to XP. Any way, My registery(sp?) file corrupted, and I know what Im supposed to do, use the Reboot or what ever its called, but the problem is that I have not been able to get into Bios, and I also never got a disk for the OS.

I know its not an XP, but could anyone help me with this? Anything I could do that doesnt involve sending it back to dell or using those disks would be appreciated.
