This error message isn't specifically connected to the image or the hard disk.
This message is coming from the PXE ROM, which is part of the motherboard's firmware load - UNDI being Universal Network Driver Interface, a service that the PXE boot firmware provides to booted modules, and a complete explanation of the Intel PXE ROM error codes explains that this means the firmware load in the motherboard is corrupt.
So, at the time this error is being generated, the system hasn't booted from the hard disk, but has gone to the network boot firmware - and that has failed. The error message speaks onto to the fact the firmware is corrupt, and doesn't directly say anything useful about the image, or Ghost, or the hard disk. A good thing to do is consider reflashing the firmware load on the machine to actually get it working properly.
At best, any connection that exists to imaging is indirect; one might conjecture, for instance, that the PXE firmware problems are latent in these systems but they only become visible because your process has not really make the restored-to disk bootable (perhaps because either the hard disk contains an existing broken MBR load which was not replaced by the imaging process, or the image contains a broken MBR load such as would happen if it was taken from a system using one of broken nonstandard multisector MBRs such as newer Lenovos).
What I would suggest is a firmware refresh to resolve the error being reported (since it is a real error, and nothing to do with the disks or imaging as such), and then to separate investigate whether the restored-to disk has been correctly been made bootable and what MBR code exactly is present in it.
