@Jakob99 Here is my next attempt, INFs are fixed and with all available translations that exist in Windows 8.0 RTM, whole INFs are 8.1 based. Hope it will succed now.

Hi, I tried your latest driver on my Intel Compute Stick with m3 cpu and Kingston M525 emmc, but unfortunately still getting 0x7b BSOD

I'm pretty sure emmc is the only problem to get windows 7 booting. I use dism to backup an existing windows 7 install from vmware and then restore it on real machines. On a nvme machine it boots into desktop right after I install nvme driver via dism. But I still can't get it working on a compute stick. 

 

Edit: I got windows 7 in a USB disk booted on Compute Stick. After I installed your driver via Device Management the internal SD reader works fine but the internal EMMC thrown a "This device cannot start. (Code 10)" error(M525 string shown in device properties though)

 

Edit2: Holy crap it works! After installing sdstor.sys for "MMC Memory Card" all of my emmc drives show in explorer. Thank you for your great work

Just an FYI, some antiviruses such as Avast, may think this is a virus. Best to disable it temporarily when handling this file.

Did it work?

I'm trying to get it to work on GPD WIN, a device built on same technology as Intel Cherry Trail tablets. Its UEFI class 3 so no any mark of bios or CSM.
It does not have BIOS INIT 10H required for Win7 to start (fixed via FlashBoot PRO, UEFISeven did not work)
It also does not comply with ACPI and throws A5 error (fixed via patched acpi.sys)
With that I've been able to boot into Windows 7 Installer but USB did not work so I couldn't continue. I've done first part of installation in Windows 10 bootloader and applied driver and all the hacks above to install.wim.
But after reboot it can't load Windows throwing that 7B error at me, please help. If we could get through, it would mean that we can install Win7 on any Cherry Trail or other Win8+ tablets which would be unbelievably awesome...

It still did not. I think it's because the hardware inside the Acer Aspire R3-131t is not defined in it even though vanilla Windows 8 Build 8056 works just fine whereas this driver, based on that, does not.
