I'm trying to upgrade our workstations from 1803 to 1909 using an SCCM task sequence. They have FDE/MEPP installed.
On our HP desktops (no pre-boot), we found that we had to change the boot order to be Checkpoint FDE followed by Windows Boot Manager for the upgrade to work. We were able to use SCCM and a HP Bios config utility to do this. After the change, we were able to upgrade most of our machines without issues. Still some machines randomly fail with BSOD's, some times re-running the upgrade will work, sometimes it takes multiple tries. Some machines are missing either the Checkpoint FDE or the Windows Boot manager option in BIOS boot sequence. Not sure how to add these options back.
On our Dell laptops (pre-boot enabled), we found that the checkpoint option is missing in the BIOS boot sequence. I haven't found a way to programmatically add this option. These laptops are running E82.50 and have BCDBOOT already enabled and we are following the SK that mentions using the setupconfig file.
I have already opened a ticket, but not very helpful and I've seen most of the posts here about upgrades.
Any times or ideas on why the FDE option would be missing?
