Perhaps your win8 machine is 64 bit vs 32 bit on win7?

comment Geoserver, Arc 10 or Windows 7 problem?
The problem is due to geoserver, it is in the exception. Perhaps you have a higher resolution on your windows 7 computers causing the issue?

Try posting the first lines of the DEM file here, it will give an idea which procedure you can use to load the file.
