Windows 7: !! Restored image of windows, now wont login, login service error!!

Hi, my windows was set up like this:
C: windows 7
F: all user accounts inluding default user ( users folder ) are on F drive.


I imaged windows, and restored it on a different PC.
On another HDD, I assigned it as F: and put a copy of the user folders on there.

But now when it goes to log in, a profile unable to login service error comes up...!!

Is it have to do with the F drive?

Is there something other than just the Drive letter, that windows looks for when searching for the users folder to login? Like HDD id/serials or something like that?



How can I fix this, it driving me crazy for too long!!




Thanks!!!!

OK, its definitely because windows cant assign the HDD as F: because it hasn't recognized it before.

So, then, is there any way to add the HDD ID and assigned letter, to the windows registry BEFORE restoring the image ( ie before imaging)??

actually, I just thought of something simple that might work, seems silly, will test to see....
