Installing Windows 7 on the pure UEFI systems without CSM

Sorry for late answer. I managed to screw up my bootloader and whatnot while doing try and error plays with bootmfgw.efi.

The HWID matches the ones defined in the INF file. I understand that it doesn't have to be 1:1 match including SUBSYS? In my case full HWID is

Code:

PCI\VEN_1002&DEV_73BF&SUBSYS_440E1DA2&REV_C0

while the driver specifies, among others:

Code:

PCI\VEN_1002&DEV_73BF&REV_C0

What I thought was odd were the Target OS versions. They were as follows:

Code:

[Manufacturer]
%ATI% = ATI.Mfg, NTamd64.6.1.1, NTamd64.6.0.1, NTamd64.6.3.3

I was worried that the ProductType (last digit) could pose a problem so I changed them to

Code:

[Manufacturer]
%ATI% = ATI.Mfg, NTamd64.6.1,NTamd64.6.0,NTamd64.6.3

of course I updated the respective sections below that as well.

I then installed this driver again (using From disk...) option. It showed me that it's not signed (even though I only changed the .inf file), but I was able to install it. I then tried fresh install (with DDU) but same results.

Unfortunately the problem persists. I also don't see anything relevant in the event viewer. What extra debug information may I provide you?

edit:
The drivers specified in the .INF file are only amdacpksd.sys and amdkmdag.sys. I can see both of them running in msinfo32.exe.

Sounds good. How do I enroll? I'd love to give this a shot with my Surface Pro 2/3

 

I'll try that today and get back to you although it's weird that AMD software also wasn't able to recognize the device/driver although it's unclear how this detection looks like.

 

So it seems I can't refresh WEI, I get "Windows Experience Index for your system could not be Computer" error.
In the C:\Windows\Performance\WinSAT\DataStore I have lines such as

and

Yes, I finally find FlashBoot Pro, Windows 7 Setup works fine, but, after 1st restart, and during setup, I always get BSOD 0x000000C2
UPD: Even with CSM and without bootmgfw patch, I always get BSOD 0x000000C2

 

After few machines testing, if you want to avoid graphics card driver code 12 error，the graphics cards can not is GTX16XX，RTX20XX and AMD RX6000 series，because they have XHCI controller and Type-C policy controller in the GPU chips，which will cause the IRQ problem.

 

Would you have any other tips and/or things to check or is that this sad moment where I have to upgrade to w10?

 

The other PCI slot yield same resulsts. I tried to disable as much as I could in UEFI but there was no other USB disable than XHCI hand off, which I have. I've also disabled additional LAN card, which changed the memory address range claimed by PCI-E "hub", though it didn't make any difference.

I don't know how to find out any IRQ conflicts because, from what I've googled, Windows should indicate that there's a conflict, but instead it shows that device is ready and that no conflicts were detected.

I tried to upgrade some drivers from MS generic ones to vendor-specific (ie. Intel PCI Controller x16 1901), though still no budge.

By disabling USB 3.x devices you mean disabling them in Windows or UEFI BIOS?

 

None driver name is displayed

The drivers is integrated by FlashBoot Pro

 

This thread is not dead and I need all the help that I can get. Lets avoid those who doesn't think it can work and stick to the plan!

Now the issue after using FlashBoot Pro to make the Windows 7 UEFI ISO (No CSM Req) once installed it overwrites the Windows Boot Manager for 8, 8.1, 10, and 11. Even if you tried to install a newer OS after 7 the Windows 7 Windows Boot Manager made by FlashBoot will not allow Windows 8, 8.1, 10, and 11 to restore the Metro Bootloader. Even worst no matter what all the boot entries minus Windows 7 doesn't work. I've also tried to rEFInd and WinToHDD Pro to make a bootable full OS USB SSD and it fails to boot to avoid overwriting the 8, 8.1, 10, and 11 Windows Boot Manager. I've also tried to take the install.wim from FlashBoot Pro's Windows 7 UEFI ISO and use the Windows 8 Developer Preview Installer to install Windows 7 in hopes to getting the Metro Bootloader that will boot Windows 7, 8, 8.1, and 10. No luck.... Any experts out there brave enough to take a shot. My issue is that I can't even boot into 8, 8.1, 10, and 11 either by WinPE, Windows Boot Manager, and using Bootice. I've also tried renaming the Windows Boot Manager using DiskGenius and EasyBCD just breaks the Windows 7 Boot Manager. Any ideas???

I've gotten FlashBoot Pro Windows 7 UEFI ISO to work on my MacBookPro8,1. I've tried installing Windows on a different SSDs and the same Windows Boot Manager by FlashBoot Pro will not allow any other Windows Boot Manager to work.

I go by Howeitworks as of today.

 

I'm also using win7 (well, I don't because the GPU issue is still present ) and win10 on single disk. My bootloader is OpenCore and I just first installed Win7 with flashboot, followed by regular win10 installation on the same disk. It "just worked".

PS: the win7 gpu issue was already happening before I installed win10.

 

@PrimeExpert Software
Why flashboot doesn't work with updated Windows 7 image of simplix iso tools ?
Does it require the original structure of Windows 7 image iso ?

The checkbox of patching Windows 7 loader doesn't even exist. when I replaced install.wim & boot.wim from retail iso with ones from simplixed iso ( iso created by simplix iso tools ). Flashboot says "VGA I/O patching can't be done because boot loader doesn't belong to Windows 7"

So what should I do to get working & updated Windows 7 installation media which is ready to be installed on pure UEFI (with no csm support) devices ??

 

create a vm (use vhd) and install graphics driver
now mount vhd and copy the files to other partition with unlocker
