After restoring an image I get "99 99 99 9999999 999999...." and so on
errors instead of booting to windows.

I originally had ZfD7 imaging partition on this machine and then
switched over to PXE. I restored the image via PXE and told it to
remove the Linux partition.

If I put the partition back and restore the image I have no problem
booting to Windows XP.

Is there some incompatability with images taken with the imaging
partition and restoring w/PXE?

I'm using ZfD7, OES-NW (6.5.4a) and Windows XP.
