I have installed GSS 3.0 on windows server 2008 x64 and during Distribution Disk Image task clients fails with a status of "Unable to boot to automation". When I modify the task Automation pre-boot environment is set to Default Automation (Auto-select) and the advance button is grayed out. I then checked pre-boot operating systems install on server and see the following Pre-boot OS
LinuxPE X86
LinusPE X64
WinPE 10X X86 (Status=Installed)
WinPE 10X X64 (Status=Installed)
None of the pre-boot os environments listed above appear in the Automation pre-boot environment option box in the Distribution Disk Image task. I am not sure how to select WinPEx 10X if it does not appear in the drop down as an option.
