All AMD TRX40 is Ok，but the bios must have CSM function.

Hey guys! So I did try to install win7 on my MSI trx40 pro and my attempt has failed. I prepared 3 options of win7: original iso, my own build with drivers and Patrick's iso eng version. So I prepared bootable usb flash and bootable DVD with each versions. And I get next results:
1)bios uefi mode, secure boot disabled, any bootable usb/DVD - PC didn't see any of it like bootable (boot priority is okay)


2)bios csm mode, secure boot settings unavailable, any bootable usb - message "reboot and select proper boot device or insert boot media..."

@FlyToha What means 'bios uefi mode' ?
Don't confuse the BIOS boot mode with its MBR partitioning and UEFI booting mode with its GPT partitioning. I use rufus for creating USB installation drives, I would recommend to do the same, therefore I can support you better.
Long live Windows 7.

@PatrickK I just wanted to specify when I used csm and uefi. Sry for incorrect wording.
I prepared two usb flash drives with my custom and your iso by using Rufus. And more one with vanilla win7 I prepared by Ms usb/DVD tool. No one from them can't boot.
Also I tried install win10 and from them install canonkong's win7 to empty and prepared nvme by using winntsetup. After reboot I get win7's setup screen "setup is updating registry settings". I did reading, after installation win7 by using winntsetup to another pc, preparing may take up to few hours. After 9 hours I still have this screen and I think it's not okay.

Guys, do you think can we launch new Ryzen chip under Win7 wing?

@FlyToha Ok, I don't understand everything what you wrote, I understand that you try to boot in the UEFI mode and that you have CSM enabled. And that the installations doesn't work like it's supposed to.
If wou write "No one from them can't boot." you have two negations there, which means to everyone is able to boot, I think you did a mistake there and you mean that your devices weren't able to boot.
I mentioned Rufus' settings in terms of GPT and MBR, what settings did you use to create your installation USB drive ?

for making the USB stick i used one of those tools;

had more luck with the one from ASROCK if i remember correctly

or

@PatrickK lol, my english so bad :D Sry for that

Yes, you right understand me. I tried with CSM and without it. In my BIOS it's called "BIOS UEFI/CSM mode"



Here screen of Rufus settings



@riku tried this AsRock's tool, get this screen when trying to boot usb drive

Anyone tried Win7 on Zen 3 CPUs yet?

@FlyToha
There's nothing you can do about that now.
Please wait a little longer until mod windows7 acpi.sys arrives.

@FlyToha Ok, that's how I like these informations, with screenshots. Ok, try it with MBR, not GPT and try again. CSM enabled, of course. Did yu disable secure boot? I recommend that anyways.
Good luk.

@PatrickK well, finaly with MBR+CSM usb was booted. But anyway i get bsod A5 :( I tried your ISO and canonkong's

@FlyToha

Ask @canonkong for the modded acpi.sys driver.
