Your Deployment Solution jobs are setup to utilize a pre-boot environment that you've chosen. For example, WinPE 4.0 (64-bit). However, when the job boots into automation, the pre-boot environment is defaulting back to Default Automation (Auto-select).
No visible errors were witnessed. When viewing the options for the automation pre-boot environment, you see your pre-boot environments listed.
Not all pre-boot environments were created
Not all of the pre-boot environments had been created. In this particular circumstance, the user was building a new server. Although the jobs had been imported, they referenced five different PXE boot images. Once the user created the rest of the PXE boot images, the jobs behaved as expected.
