Well, the term "image" means all that it implies, which is to say
that it carries the contents of the original environment - which will
be in conflict with the current environment if that differs.

You can find information on using Windows PE and BartPE in the TSM
Field Guide:
"Tivoli Storage Manager Recovery Techniques Using Windows
Preinstallation Environment".

You should probably instead look into ASR recovery methodologies...
As Tivoli Field Guide "Using Microsoft Windows Automated System
Recovery (ASR) to Recover Windows XP and Windows 2003 Systems with
the IBM Tivoli Storage Manager Backup-Archive Client for Windows" says:

"The hardware configuration of the target system must be identical to
that of the original
system, with the exception of the hard disks, video cards, and
network interface cards."

The topic of Windows BMR has, of course, been exhaustively discussed
on this mailing list. See archived postings for excellent
contributions in this area.
