Diveimage xml problem

So I heard so many bad things about Ghost and what not, so I decided to go with Driveimage xml. No one had anything really bad to say about it and hey, it's free. So I ran it and saved the 3 files it created to a usb HD. Ran the restore, and it seemed to go fine...confused ....until I rebooted and now it says "Missing operating system".:cry Did I miss something? I'll reload XP if I have to but I'd like to see if this works. Thanks :major

 

I've used DriveImage once or twice ages ago - doesn't it let you choose the areas you image? You DID image the OS, didn't you???
