Apple MBP: UEFI installation won't boot after image apply

Hi, last few hours I spent trying to manually deploy Windows 10 on clean GPT disk but after applying image and rebooting I always end in unbootable state.

I manually setup drive like this:

Code:

select disk 0
clean
convert gpt
create partition primary size 350 #RE tools won't fit 300MB anymore :-)
format quick fs ntfs label "Windows RE tools"
assign letter t
set id de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes 0x8000000000000001
create partition efi size 100
format quick fs fat32 label System
assign letter s
create partition msr size 128
create partition primary 
format quick fs ntfs label Windows
assign letter w
list volume
exit
#no recovery image partition as per documentation it is no longer needed

and followed by pretty common deployment:

Code:

dism /apply-image /imagefile:g:\Sources\install.wim /index:1 /applydir:w:\
dism /image:w:\ /set-Timezone:"Central Europe Standard Time"
md T:\Recovery\WindowsRE
attrib w:\Windows\System32\Recovery\Winre.wim -h -s -r
copy w:\Windows\System32\Recovery\Winre.wim T:\Recovery\WindowsRE\winre.wim
bcdboot w:\windows /s s: /f UEFI
w:\Windows\System32\reagentc /setreimage /path T:\Recovery\WindowsRE /target w:\Windows

After reboot I always end unbootable (as we talk Apple computer it means 1) no partition on Option or 2) folder with ? or 3) just gray screen, make your pick). There's a chance that Windows rely on some UEFI 2.0 feature, which is not available as the old guy has 1.2 only. Or maybe I missed some step somewhere. Any ideas?

Only macs with PCIe SSD support UEFI. For MBP that is only retina versions from late 2013 or more recent (your 5.1 is 2009 I think). Even if you can get UEFI to boot you'll get no sound etc as there aren't any drivers.

You'd want to use BIOS emulation. Method is (actually simpler):

diskpart
list disk
Take note of the disk you want to select
select disk 1 (if your disk is Disk 1)
clean
convert mbr
create partition primary
format fs=ntfs quick label=Whatever
assign letter=E
exit

Open up File Explorer. In your C drive, create a new folder named WIN2GO.
Put the install.wim file in this folder

Back in cmd.exe:
dism /apply-image /imagefile:C:\WIN2GO\install.wim /index:1 /applydir:E:\ (this process will take quite a while)
E:\Windows\System32\bcdboot E:\Windows /s E: /f ALL

halasz: Actually, that's not true at all. If you don't mind MBR (BIOS emulation), you just pop Windows DVD into drive and install them like on any other laptop. All drivers are available in Windows Update immediately (chipset is nForce, audio is generic Realtek, etc..), I was running that MBP5.1 with Win 8.1 for the whole last year. Now I even have Windows 10 there, again, fully working, all devices installed, but only MBR. All those extra steps are required only in case you want to run UEFI, not legacy (or when you do not have optical drive and your MBP is too old to be able to boot from USB). Apparently, I'm just missing some step to have it running from UEFI from GPT and that's why I asked here. (overly simplified but let's pretend MBR='BIOS Emulation'=legacy and GPT=UEFI, even though they are different things, in this context I mean it the same)

For those who would ever think about doing the same as me, running MacBook with Windows only, the less known fact is that all you need from bootcamp is \Drivers\Apple\(x64)\bootcamp(x64).msi. You need:
bootcamp 4.x for Win 7
bootcamp 5.x for Win 8(.1)
and now
bootcamp 6.x for Win 10.
As Apple do not freely distribute bootcamp package anymore (from 6.x up), you need to get your hands on any Mac, run BCA and let it create USB with drivers from Apple update (hefty 3GB download just for 5MB of bootcamp.msi). While setup.exe won't let you run it on unsupported hw, you do not want to run setup.exe anyway. In elevated command prompt you run 'msiexec /i bootcamp.msi' and your BC control panel is installed, providing you with:
Keyboard backlight
Choice between F1-12 and function keys
Touchpad controls (like right click with double touch)
OSD for function keys
and a few other small things.
In all the other aspects it behaves like generic laptop (no UEFI user iface etc, but you've got the idea).

TL;DR: You can install Windows on any MBP like on common laptop, you don't even need OSX for that. Just install correct \Drivers\Apple\(x64)\bootcamp(x64).msi after installing Windows to have it fully working.

I would turn this into some kind of guide but dunno where and how. Hopefully it will help to someone who runs over it incidentally.
