|What you spell out may be possible. If the new computer has only one hard drive, you may have to repartition that drive to shrink the original partition and leave enough free space to image the old system to. You'd have two partitions that each show up as a separate drive letter.|
However, my concern is that the imaging software may try to change the boot sector on the new systems drive to boot off the old system.
Instead of imaging, instead of copying the old drive to DVD's as an image, just copy the data files you need to the DVD's, and then copy the files to a folder on the new system.
Of, if the imaging software can be installed on the new system so that the data files can be read from the image files on the DVD, then do that and again, just copy the files from the old system to a folder on the new system.
Another option is to install Microsoft's free Virtual PC software, create an empty virtual machine file and image the old system to the virtual machine. Then you can boot up and run your old system on the new computer, programs et al. That would take more work but might yield you the most desirable result, depending on what your aim is.
