Hi Cliff,
If you want to exit to DOS, use CTRL+X rather than CTRL+C. CTRL+X would exit to DOS, and you can run 'GHREBOOT' to go back to Windows.
I checked this in our systems, and the image creates by Ghost Boot Wizard is OK. Most probably your situation was caused by a previous Ghost Boot Partition present in the PC. Was there are Ghost Boot partition already in the PC? If the previous copy of boot partition worked OK, now the new one also should work.
If a Ghost Boot Partition was present in the machine at the time of imaging, and if it was not hidden (then you could access it as drive C:), delete the file MBR.BIN from C:\ before imaging the machine with another Ghost Boot Partition. If it is hidden, it should not be a problem.
If you select 'overwrite ghost boot partition' switch, it will force Ghost to remove the Ghost Boot Partition. If you are running a Console task to deploy an image with a Ghost Boot Partition, this switch should be used. Other use of this switch is to convert the machine from using Ghost Boot Partition to Virtual Partition. If the image you are deploying does not contain a Ghost Boot Partition, still this will delete the Ghost Boot Partition and continue to work with a Virtual Partition.
Does this happen at all (or many) machines you work with? What is the state of the hard disk prior to imaging it with Ghost Boot Partition? (Is it in Windows, Ghost Boot Partition etc.)
If you try installing the client using Remote Client Install and use the Virtual Partition, does it work OK?
