Wimboot UEFI Crash/Bootloop

[Zer0Cool]

Hello,

Dell Precision Tower 3620 (latest BIOS), UEFI (secureboot OFF)
wimboot 2.6.0

Code:

kernel http://${fog-ip}/fog/os/win/wimboot pause gui
initrd --name BCD http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/BCD BCD
initrd --name boot.sdi http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/boot.sdi boot.sdi
initrd --name boot.wim http://${fog-ip}/fog/os/win/winpe/amd64/media/sources/boot.wim boot.wim
boot || goto MENU

This machine boots and displays the iPXE menus. In BIOS boot WinPE boots just fine. In UEFI after selecting the entry it downloads the 3 files. wimboot starts patching the boot.wim. It gets to the point that its found and loaded bootx64.efi and then immediately reboots (with a single loud beep from the PC). In other words it never actually loads winpe.

Its worth mention that iPXE will run other installers on this machine UEFI booted just fine (like CentOS 7). The above entry will run UEFI on a Dell R620.

Some background tidbits. I created the winpe via a Windows Server 2016 box with the latest MDT and ADK installed, everything updated. Used

Quote:copype amd64 /path

.

I also tried via dism adding in the dell winpe10 drivers pack from their website (version 1.0 A08). Extracted the cab, ran the dism command to add drivers. It added about 65 drivers, unmounted and commited changes.

Worked in BIOS boot, still the same issue in UEFI on the Dell 3620.

I have tried without the gui line, tried with rawbcd, tried with -n instead of --name.

I am at a loss here, any advise would be great. Thanks
