GPT Windows 7

[bingloverld]

Hi,

I must install Windows 7 Enterprise with imagex. Until now I have always installed with MBR partitions. But now my boss said that we must install with GPT. Unfortunately this don't work.

Here are the steps which I make:
diskpart
select disk 0
clean
convert gpt
create partition primary size=300
format fs=ntfs label="Windows RE tools"
assign letter="T"
create partition efi size=100
format fs=fat32 label="System"
assign letter="S"
create partition msr size=128
create partition primary
format fs=ntfs label="Windows"
assign letter="W"

than:
imagex /apply ?:\Install-Images\Path\wim_file.wim 1 W:

where ? ist Source Medium with *.wim file

Now I have tried all methods with bcdboot for example

W:\Windows\SysWOW64\bcdboot W:\Windows /s S:

But this don't work (say the boot files are successfully copied but windows boot not)

On Laptop I have Legacy. I don't know if GPT works with Legacy or only with UEFI.

I must install this with this routine (diskpart, imagex, bcdboot).

Thank you for your help

Sounds like you have a PHB. :/

Officially you can only install to GPT on a UEFI system. I believe there are hacks and workarounds but I have no experience with them.

I hope your boss knows this.

Ask him what his reasoning is for doing this.

Hi,
Most likely an insistence to use bitlocker
About the only perk of uefi installs that I'm aware of.

You don`t have to install to GPT to use bitlocker.

Bitlocker is part of the OS

Ok

I have found a solution.

I make normal clean install Windows 7 but with GPT partitions.
Than I created *.wim image and now I can use imagex and gpt partitions.

I would like to try this. I know how to create a .win file and apply the image, but could be a little more clear on the steps you took. Did you clean install Windows 7 to a MBR partition, create the .wim, and then apply it to the GPT partition?
