are you using efibootmgr in FOG?
I was testing using partclone manually restoring an image and it wouldn’t boot. I was able to boot a linux live cd, and using efibootmgr repair the boot menu manually.
As far as I am aware, the only way to fix non bootable UEFI from windows tools is BCEDIT, however seeing as you boot a linux kernel to apply the image using partclone, maye you can script efibootmgr afterwards to repair the UEFI on the system and make it bootable.
Or is it a different issue entirely with FOG?
efibootmgr should be scriptable
usage: efibootmgr [options]
-a | --active sets bootnum active
-A | --inactive sets bootnum inactive
-b | --bootnum XXXX modify BootXXXX (hex)
-B | --delete-bootnum delete bootnum (hex)
-c | --create create new variable bootnum and add to bootorder
-d | --disk disk (defaults to /dev/sda) containing loader
-e | --edd [1|3|-1] force EDD 1.0 or 3.0 creation variables, or guess
-E | --device num EDD 1.0 device number (defaults to 0x80)
-g | --gpt force disk w/ invalid PMBR to be treated as GPT
-H | --acpi_hid XXXX set the ACPI HID (used with -i)
-i | --iface name create a netboot entry for the named interface
-l | --loader name (defaults to \elilo.efi)
-L | --label label Boot manager display label (defaults to “Linux”)
-n | --bootnext XXXX set BootNext to XXXX (hex)
-N | --delete-bootnext delete BootNext
-o | --bootorder XXXX,YYYY,ZZZZ,… explicitly set BootOrder (hex)
-O | --delete-bootorder delete BootOrder
-p | --part part (defaults to 1) containing loader
-q | --quiet be quiet
–test filename don’t write to NVRAM, write to filename
-t | --timeout seconds Boot manager timeout
-T | --delete-timeout delete Timeout value
-u | --unicode | --UCS-2 pass extra args as UCS-2 (default is ASCII)
-U | --acpi_uid XXXX set the ACPI UID (used with -i)
-v | --verbose print additional information
-V | --version return version and exit
-w | --write-signature write unique sig to MBR if needed
- Root can use it to display the current Boot Manager settings.

Boot0000* Diskette Drive(device:0)
Boot0001* CD-ROM Drive(device:FF)

BootCurrent - the boot entry used to start the currently running
BootOrder - the boot order as would appear in the boot manager. The
boot manager tries to boot the first active entry on this list. If
unsuccessful, it tries the next entry, and so on.
BootNext - the boot entry which is scheduled to be run on next boot.
This superceeds BootOrder for one boot only, and is deleted by the
boot manager after first use. This allows you to change the next boot
behavior without changing BootOrder.
Timeout - the time in seconds between when the boot manager appears
on the screen until when it automatically chooses the startup value
from BootNext or BootOrder.
Five boot entries (0000 - 0004), the active/inactive flag (* means
active), and the name displayed on the screen.
An OS installer would call ‘efibootmgr -c’. This assumes that
/boot/efi is your EFI System Partition, and is mounted at /dev/sda1.
This creates a new boot option, called “Linux”, and puts it at the top
of the boot order list. Options may be passed to modify the
default behavior. The default OS Loader is elilo.efi.
A system administrator wants to change the boot order. She would
call ‘efibootmgr -o 3,4’ to specify PXE boot first, then Linux
A system administrator wants to change the boot order for the next
boot only. She would call ‘efibootmgr -n 4’ to specify that the
Linux entry be taken on next boot.
A system administrator wants to delete the Linux boot option from
the menu. ‘efibootmgr -b 4 -B’ deletes entry 4 and removes it
A system administrator wants to create a boot option to network
boot (PXE). Unfortunately, this requires knowing a little more
information about your system than can be easily found by
efibootmgr, so you’ve got to pass additional information - the ACPI
HID and UID values. These can generally be found by using the EFI
Boot Manager (in the EFI environment) to create a network boot
entry, then using efibootmgr to print it verbosely. Here’s one example:
In this case, the ACPI HID is “0A0341d0” and the UID is “0”.
For the zx2000 gigE, the HID is “222F” and the UID is “500”.
For the rx2000 gigE, the HID is “0002” and the UID is “100”.
You create the boot entry with:
‘efibootmgr -c -i eth0 -H 222F -U 500 -L netboot’
