Windows 8 install USB external HDD on UEFI system with Windoes To Go fail fail fail

Question

i want to install Windows 8 to USB external HDD on UEFI system, but when setup 100% and then always stay here "getting ready" show error common diaglog "Windows Setup could not configure Windows to run on this computer's hardware."

and my step:

in Windows 8 OS and BIOS UEFI mode
start administrator cmd prompt:
diskpart
clean
convert GPT
create par EFI size=100
create par msr size=128
create par pri
sel par 1
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
format fs=ntfs quick lable=Recovery
sel par 3
format fs=ntfs label=OS quick
assign letter=o
DISM.exe /Apply-Image /ImageFile:install.wim /index:1 /ApplyDir:o:\
bcdboot o:\windows /s o: /F ALL
reboot
press F12 from USB external HDD boot

setup 100% and then stay here "Getting ready" show error common diaglog "Windows Setup could not configure Windows to run on this computer's hardware."

i have tried out others way:

sel disk 1
clean
convert GPT
create par EFI size=300
create par EFI size=100
create par msr size=128
create par pri size=20000
sel par 1
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
format fs=ntfs quick lable=Recovery
assign letter=r
sel par 2
set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b                                                        
format fs=fat32 quick
assign letter=s
sel par 4
format fs=ntfs label=“OS” quick
assign letter=o
DISM /Apply-Image /ImageFile:install.wim /index:1 /ApplyDir:o:\
bcdboot o:\windows /s o: /F ALl
