I've created an image that has been exported on numerous Dells and Gateways. However, when I try to put it on a HP dx5150, it continuously reboots afterwards. But when I create an image of the dx5150 and export it to other dx5150s, it works fine. What am I missing?

so you created an image from Dell machine and restore it on HP dx5150?
Did you use sysprep? if you don't use the sysprep, you should use the similar hardware. maybe dx5150 have a special hardware compare to Dells or Gateways.
