@FlyToha Cool, one step further.
I suggest that you ask canonkong or anyone else for this, claimed, modded acpi.sys file to fix this.
I wish you good luck.

@PatrickK by using Gimagex i did mount install.wim (it's transformed @canonkong 's Win7.esd file), then i replaced all original acpi.sys files to modded, which i did find in mount's directory.



Then i did unmount image and i replaced the original install.wim to modded install.wim in the original Win7 ISO by using Ultraiso.



Next i did prepare new bootable usb drive by using Rufus with MBR option (i tried GPT, but not working).



And again i get BSOD A5. I think problem or with my mobo, or in CSM mode (or i have hands from ass :D). Becouse in UEFi i cant boot usb drive and dvd. Rufus maked one more partition on usb drive with bootx64 files for possibility booting usb with UEFI, but on my PC it not working.
Most productivity way in my attemts - trying install Win7 by using Winntsetup, becouse by this way i get installed Win7, but after reboot i get infinity "Setup" screen. I have no more ideas, what i can to do :(

I don't know how this with this modded file works, don't ask me about this. Afaik, Windows 7 works on some boards and on some it doesn't but there are other people which know better about this thing. Anyways I recommend to update to the latest UEFI version, if not already done.

@FlyToha

When you already have BSOD when trying to run Setup, i think you have to replace the acpi.sys in boot.wim too, in both images maybe.

EDIT:
Index 1 is Microsoft Windows PE (x64),
Index 2 is Microsoft Windows Setup (x64)

@VelleX Thanks man, good point, I didn't think about that.

@VelleX thank you for this tip! I'll try it

@FlyToha
I edited my Post.

Dont forget to change both Images in boot.wim, Index 1 and 2

@VelleX Wow man! Its working! Finaly i get Win7 installation screen! But now i have another problem: Win7 cant find any drivers even if i select drivers folder manualy.

@FlyToha

Did you get an error message like this? Or do you have a other problem?

A Required CD/DVD Drive Device Driver is Missing

---

I had this problem last year, but i simply switched the USB Port and then it was working. I just removed the USB Stick and plugged it into onother port while Setup was running.

@VelleX yes, i did get this message. And i did prepare new bootable DVD. But now i stuck on this problem: When i trying select my nvme for Windows, i get error 0x80300024. I tried to clean disk by using DiskPart, but it not fixed problem.



On my PC DVD and USB working only with CSM. When i trying to boot usb drive or dvd with UEFI i get this error "The boot selection failed because a required device is inaccessible"

@FlyToha
Google says that you should try to remove or unplug other disks in the system, so that only one drive is visible

And for the uefi problem, you could try uefiseven

Edit: or did you already?

@FlyToha

for your missing storage devices there is a backported storahci driver on sourceforge you can try -

https://sourceforge.net/projects/storahci-for-windows-2003/

there is a precompiled driver in the /bin folder - integrate that into both boot.wim images using NTLite.

I'm not sure if the existing msahci driver will conflict though - it might need to be removed.

I recommend to remove every drive, except the one you want to install on. And delete every partition and do not try to install into an already present partition.

@PatrickK

If he can't see his storage drives at all it's a driver issue.
