Hi,
I force computers (with UEFI) to boot from HDD (Windows bootloader) with this command in snapin:

#Booot from HDD
#Snapin works only with Powershell x64 Snapin Template?
#Use at your own risk! No warranty!
c:\windows\system32\bcdedit.exe /set “{fwbootmgr}” displayorder “{bootmgr}”

We use it after imaging because PXE boot is too slow.
