    Hello,

    Hope to get help here. I am stuck on installing Win 7 on my new computer (AMD Ryzen 3000 series, MSI Mortar B450 Mainboard, Crucial P1 NVMe 1GB SSD).
    Other Windows versions are no options for me. I read on different sites in the internet that it is possible to run Win 7 on new Ryzen systems.

    I already some things. My BIOS is up to date, I flashed it two weeks ago

    I successfully installed Win 7 (keyboard and mouse connected via USB worked perfectly fine during the installation process).
    After the first reboot during the Windows logo I got a BSOD.
    First it was this one: 0x0000007B (0xFFFFF880009A97E8, ...).
    Later after some trying I got this one: 0x000000A5 (0x00000011, 0x00000008, 0xF77971F0, 0x20120913), saying that my BIOS is not fully ACPI compliant.

    Then I changed the SATA mode in BIOS from AHCI-mode to RAID-mode (there's only these two options available).

    I also activated BIOS UEFI/CSM mode.

    After that I got 2-3 seconds further with the Windows logo. No BSOD. But nevertheless the boot procress crashed and my computer does restart every time at that point.

    Then I tried to start Win 7 in safe mode. While loading all the drivers this process got stuck at: ahcix64s.sys
    So far I don't know what to do to finally be able running Win 7.

    I'd be very happy to find helpful assistance with my problem here.

    Thank you

    Windows 7 = BSOD. Switch to 10.

    Thanks Joe C,

    I am aware of what you quoted from Tomshardware. But I don’t care. I am fine with that potential limitation.

    My CPU is a 3700X. So should be fine, right?

    The thread you’ve linked is interesting. I’m downloading the file from post #1 and will try it.

    Any other suggestions?

    Please refrain from recommending me Windows 10, I will not consider it.

    Thanks for the link.
    But how exactly do I get the drivers implemented so that I can flawlessly boot until the GUI?
    I don’t know how exactly to include the driver as I can not access the win 7 desktop.

    Would you be willing to test my tool, it creates an uptodate win 7 install iso with usb3.x drivers and some nvme drivers, i don't have the hardware to test it on.

    Thanks for your offer. Ok, let's test it.
    I'll download the zip file.
    Any prior instructions?

    I only have a Win 7 Ultimate image, does that work too?

    All instructions are on the link i gave, you only have to provide the 2016 LTSB iso and the windows 7 iso(s) (i would advise to either run the aio with enterprise or enterprise only cmd, because of UEFI needs, it can be activated by KMS_VL_ALL on UEFI/GPT installs)

    People make custom windows 7 ISO with the needed drivers slipstreamed into the custom ISO.

    Keen to see how things go as I may be making a 3600x with b450/470 mobo in a few months and will try getting windows 7 working on it too.

    Just ignore the folks saying install windows 10 btw as they are just being rude saying such things in a thread asking for help on installing windows 7 in a windows 7 forum board.

    It was solved by making a hybrid win10/7 iso, basically i've put the german win 7 install.esd (made by the tool mentioned) inside a german windows 10 iso (cleaned up manual setup files).

    All worked.

    Oh great using the tool you created I gather?

    If I understand correctly your tool makes a custom windows 7 install with the required drivers for ryzen 3k cpu's but uses the windows 10 installer?

    Atm it still modifies a win 7 boot.wim to handle the install.esd but there will be another script that uses the full win 10 boot but looks like 7 as much as possible.

    Very nice, will be trying this out for sure on a 3600x and most likely a 3700x. Thanks for the tool!

    The problem isn't so much the CPU, it's the platform and it's drivers.

    Yeah I understand that, I know you can get past ryzen cpu working fine on 450/470 or older platforms as long as the mobo maker offer the required drivers up on their website but there has been many people having issues getting the 3k cpu working right on the 450/470 mobo's due to bios issues.
