Anyone ever use spotmau?

I had an extra Dell desktop that was gathering dust and a friend with an OLD XP based HP needed a faster PC. I wiped the HD with Ctrl + F11 and uninstalled all the BS that comes on a Dell. Then used Spotmau to clone his 18 G HD onto the Dell's 80 G HD. Both are XP machins and now when I try to boot it from the HD all I get is an error that says "failed to read disc. Press alt ctrl del to reboot. I have a similar Dell desktop that I use daily, can I put the HD out of the f***** one into the good one as an extra drive (it's got a place for it) and reinstall the Dell factory settings to it? I've moved a couple of times and can't find the factory discs for either Dell. HP machine is still good, just so slow you want to throw it out the window when you get on it.
Good PC : Dell Dimension B110 w/ 80G Seagate HD, 2.56GHz Celeron CPU, and 512 MB RAM. Running XP Home Edition 2002 w/ SP3
other dell is almost identical except it only has 256MB RAM.
I thought "XP w/SP3 is XP w/SP3 ", obviously not because now it will only boot from the Spotmau Boot CD and not from the HD. I can't afford their Tech support so right now I'm kind of stuck. The only other option I can think of

 

Hi grantman,

Ctrl+F11 is the restore function on a Dell
Wipe the drive properly by reformatting,primary with MBR and you'll have a drive that will boot if an OS is installed on it.

BUT, problem here is also that you're using an HP OEM installation,
so while it may initially run,you won't be able to activate it.

The cloned OS has the HP "stamp" all over it.Hardware hashes are totally different.So you would need the Dell hardware drivers CD.
Even so, activation won't pass.
So I'm afraid it's a no-go - sorry

Now, if the HP had a retail version of XP, things are different.
you just install it on the 2nd Dell.Get missing drivers for that machine from Dell.
BTW that machine is just marginal with only 256 MB of RAM -won't be much better than the HP and will experience a lot of "freezing ".

Sorry for the discouraging answer,but can't change the facts

Pete.
