Ghost.exe compatibility

I have been using Ghost to provide much-appreciated reassurance backing up my various Dell PCs for many years. I frequently experiment with operating systems and utilities, so being able to restore from a second hard drive simply is invaluble. The simplest way I've found is to run Ghost.exe from a DOS boot disk.

 

My latest Dell (Pentium D 915 Dual Core) is incompatible with Norton SystemWorks 2003, presumably because it won't run PC-DOS 7.

 

What is the simplest solution?
