Sorry for delay.
As I have no experience with the Media Center OS, I request that someone else explains the procedure.
From what I have read through Google search, it needs rather more attention than a standard XP re-install.
But you should have an OS recovery disk/s or DVD with your Dell system and I read somewhere
you may even have the stuff on a hard disk recovery partition. You will have to look at
your manual, or ring Dell Support.
WARNING - obvious really, you must backup your own personal stuff first,
because it must be the case that any reinstall is going to format your Hard Disk
and further, if you put any service packs on after you got your system,
they will doubtless have to be reinstalled after your computer (hopefully) returns to normal.
(And all your software - what a bummer - let's hope you can do better with system restore).
Hopefully, someone who knows MCE can jump in here. Anyone?
Good luck. Have a nice day!
