Well it looks like this is definitely a problem with this model of laptop. The Windows 7 Enterprise installer finished copying and expanding all of it’s files and then as soon as the first reboot happens the computer hangs at the same black screen I receive after imaging it. Looks like I’m destined for the HP support line to kick this up the chain for a fix :(.
Edit: I just rebooted without the network cable plugged in and now the installer continued without an issue. More testing needed but maybe an issue with how the FOG boot menu is handing back off to the boot cycle on this model. I’ll update once I’ve done more thorough testing.
Edit 2: The solution for this is that the “Host Bios Exit Type” for this model must be set to “GRUB” or it will hang before the OOBE portion of the Windows install process starts. “SANBOOT” causes this 100% of the time on our units and “EXIT” returns an error. Presumably any of the “GRUB” options would work but I haven’t verified any other than the basic “GRUB” option.
