Is this not the same error you were getting before?
What concerns me is the message about returning to windows. Can I check that you are NOT trying to run Ghost under a command prompt from within windows? You need to be booting to DOS.
Can I also check, if you are booting direct to DOS, what sort of boot device you are using. It is a floppy drive on a USB port, or a USB stick ?
I don't know if this is your first job or a change of job, so I may cover ground you are already familiar with.
Modern hardware comes with SATA hard disks, for which DOS has NO support at all. In order to allow DOS to talk to SATA hard disks, you need to go into the BIOS and under hard disk settings, enable "compatibility mode". It may be called something else, but essentially it translates SATA instructions into the older PATA format. DOS also has limits on the size of hard disk it can access and bioses can only get around this to a limited extent.
That is why you will find that the general recommendation nowadays is to dump DOS in favour of WinPE. This is a command line operating system that is based on the Windows kernel and therefore can use Windows drivers to access modern hardware such as the latest NIC chipsets and SATA chipsets. If the version of Ghost you are using is 11.5.1.2266 then the software already includes a version of WinPE that can be used to build boot environments. Due to the age of Ghost, the version of WinPE is based on the Vista kernel but there are articles in Connect on how to use WinPE V3 with Ghost, which is based on the Win 7 kernel and uses Win 7 drivers.
Finally, in respect of your DOS version in your current boot environment, is it based on XP or another version? Mae sure if testing a different version of HIMEM.SYS that you have either replaced/renamed the old version or correctly changed the path in config.sys Occasionally, there may also be issues with mouse drivers in autoexec.bat, so you can rem out any calls to a mouse driver as a test.
