Under the BIOS are you able to set the SATA Hard Drive controller to Compatibility or IDE? Remove it from ACHI or SATA control. This will allow Windows XP, and ghost boot disks to see the HDD

That works great with our HP's, Fujujitsu's and Motions but not Panasonic.
I should have put that in the first post. Panasonic doesn't provide that option. I had to ask their tech support because I couldn't find it in the BIOS.

Found a way to make it work. We changed the WinPE boot model to "Boot Windows PE using the 'factory -winpe' model" Step #7. Worked like a charm.

Where in DS is this setting? Step #7? We have a couple of Toughbooks coming in and would greatly appreaced a tiny more info on what you did to fix your issue. Thanks in advance.

If you go into PXE Configuration Utility, choose your boot option you want to edit, click on "edit" and then "edit Boot Image," This will open Altiris Book Disk Creator step 9 of 12. If you click "back" it will walk you through the steps until you get to step 7 and that is were you make the change then just continue through. If you have not added the mass storage device driver you will need to do that in step 2.
Hope that helps.

Thanks that worked!
