Windows 7: Install Windows 7 in pure UEFI (problem with GOP)

Install Windows 7 in pure UEFI (problem with GOP)

Hey guys, I have been trying to install Windows 7 on my laptop in UEFI mode with GPT for hours without any success. I have an Acer laptop that came preinstalled with Windows 8, I upgraded it to Windows 10 and was using it for a while but I still don't like it and really wanted to switch back to 7 all that time, I did once, but I had to use Legacy mode and MBR disk. I did not like it much because the boot times were slow and for some reason I really want to use a system with UEFI and GPT disk scheme.

Long story short, when I create a bootable Windows 7 USB and boot from it in UEFI mode, I get the well known "Starting Windows" screen freeze/hang. After doing some research it seems that it is the trouble with the new GOP feature that UEFI uses, and indeed in my laptop I can see a Intel GOP listing in Main panel in BIOS/UEFI settings menu and from what I saw Windows 7 default drivers do not support GOP hence the reason why it hangs.

I have stumbled upon an article that explains how to inject drivers into install.wim and boot.wim images using DISM. I have added drivers using that method and even removed/disabled the standard driver vga.sys, that apparently causes the problem but unfortunately I with no success. It still freezes in startup but this time it freezes even before at "Windows is loading files...".

The ISO image I am using is an official MSDN image of Win 7.

So basically, I am asking maybe somebody has had this issue before and managed to solve it, and even if it is possible at all to install Win 7 in UEFI with GOP graphics card.

Thank you in advance!
P.S. Sorry for my English it's my second language.

Did you try installing without a graphics card, although I don`t think the GPU has anything to do with your problem, but I`m no expert

Have you installed a solid state drive in this laptop yet ?
What do you mean by deleting drive to unallocated space?

It is a laptop so I don't think there is a way to unplug the graphics card.

Yes, I have an SSD and HDD.

By that I mean did you remove all the partitions off the drive so it shows nothing but unallocated space ?

Step #7

Clean Install Windows 7

Ya I had a Fubar with the graphics card seeing that you`re working on a laptop, ignore that.

You may have to disable Secure boot in the Bios, maybe you should ask this question in Windows Eight Forums ?
