KRNL386.exe

I think I wasn't clear enough previously.
I have a computer with DOS 6.22 & Windows For Workgroups 3.11.
Everything is working fine; but it will fail sometime and I need to backup.
I am trying out an image program "Image For Dos". When I backup the current computer with this program and then restore it in a new computer, I am using the first partition on the new computer - as on the old - and the image restores just fine. However, when I start up WFWG 3.11, I get the splash screen and seconds later I get the message: "Cannot find or load required file KRNL386.exe". However, KRNL386.exe is located in the \Windows\System directory - as on the original computer.
I have tried everything on Microsoft's Q70467 article to no avail. I suppose with all the time I've spent with this, I could have loaded this from scratch. However, that would still leave me with the same issue of not having a backup.
