efi bootable works on haswell (late-2013) or later macs. not work on mac.

way have efi on external drive use method:

connect external drive windows vm. must have windows vm in vmware/parallels/vbox, or windows pc. existing windows environment do.

need:
install.wim file (obtain windows iso)

open elevated cmd.exe (run admin)

note: commands aren't case sensitive, including pathway files.

type diskpart
type list disk
take note of disk want select
type select disk 1 (if disk disk 1)
type clean
type convert gpt
type create partition efi size=100
type format quick fs=fat32 label=efi
type assign letter=s
type create partition primary
type format fs=ntfs quick label=w2g (or other name wish label)
type assign letter=e
type exit

open file explorer. in c drive, create new folder named win2go.
put install.wim file in folder

in cmd.exe:
type dism /apply-image /imagefile:c:\win2go\install.wim /index:1 /applydir:e:\ (this process take quite while)
type e:\windows\system32\bcdboot e:\windows /s s: /f uefi

restart entire mac. after chime, hold down option , when prompted select boot drive, select efi boot.

proceed installation normally.

after installation, install boot camp drivers. feel free trash vm once you're done too.

best results, use usb 3/thunderbolt. if don't have usb 3, use thunderbolt. if have neither, stick internal drive :)

note: method works windows 8/8.1.
