WinPE x64 UEFI boot error 0x7f048283

Sorry, missed the linked pastes.

Not sure why you have separate items for efi and non efi wimboot should work just fine with both, and you should not have to specify the efi. (it is automatically extracted from boot.wim)

and if you then are using wimboot, I'm assuming that ipxe starts wimboot just fine and you can see the output from wimboot?

My recommendations of your script below

Code:

:WinPEx64
:WinPEx64UEFI
kernel http://192.168.100.1/wimboot gui pause
initrd -n BCD http://192.168.100.1/winpe/x64/Boot/BCD              BCD
initrd -n boot.sdi http://192.168.100.1/winpe/x64/Boot/boot.sdi   boot.sdi
initrd -n boot.wim http://192.168.100.1/winpe/x64/sources/boot.wim   boot.wim
boot || goto failed

added gui since it might be an issue in efi land without it sometimes. also added the pause so you can see that everything is in order before boot is handed over to windows bootmgr.

If you still get issues you might want to try with a minimal BCD, you should be able to use this one for all variants of wimbooting.
