OK, so when you boot up with the cd and ghost loads up, either press ctrl+c or use the gui to quit out of ghost and back to the command prompt. It is at the command prompt where you can specify command line arguments for ghost. You will need some writable media attached to set as the destination for the error file, you can save it to another disk, usb floppy/flash or a network location if you have mapped a network drive.
Make sure your writable media is attached before you start the machine. Boot up, quit out of ghost and then type gost.exe -afile=<drive letter of writable media>:\myErrorFile.txt
ie. ghost.exe -afile=d:\errorFile.txt
If you are in DOS then you'll need a FAT file system to save to as NTFS will not be given a drive letter in DOS.
I find building a PC-DOS bootable USB flash drive is easiest for this scenario that way you can include other GSS tools that may come in handy such as gdisk.exe and omnifs.exe.
Once you have an error file you may be able to diagnose the problem yourself or you can post it here.
