When imaging a Dell Venue machine using BIOS firmware (instead of UEFI), the task sequence failed with the below error:
Task Sequence has failed with the error code (0x00000001) – UEFI/BIOS
When viewing the smsts.log I saw:
Marking partitions active is only supported for MBR disks.
Unable to activate partition (0x80004001)
Failed to make volume C:\ bootable. Code 0x80004001.
Failed to make volume C:\ bootable. Please ensure that you have set an active partition on the boot disk before installing the operating system. Not implemented (Error: 80004001; Source: Windows)
I checked the Task Sequence, and there was only a step to format the disk as UEFI. The boot mode on the Dell Venue was set to Legacy/BIOS. You can see in the Task Sequence below, the Disk Type is GPT (which is UEFI).
After setting the Dell Venue to UEFI firmware and booting from the NIC, the disk was formatted and the Task Sequence did not fail.
