BIOS is not ACPI compliant BSOD while installing Windows 7

[mahaju1]

I have a 15-db1000AU HP notebook

CPU is AMD Ryzen 3 64 bit

 Motherboard is  HP 85EA, BIOS is Insyde  F.13 - AMD AGESA PicassoPI-FP5 1.0.0.6

When installing Windows 7 64 bit Professional it crashes with a Blue Screen message "BIOS is not ACPI compliant (error code: 0x000000A5)

The BIOS has an option called compatibility support which is enabled, and the description says this option should be enabled to support older OS like Windows 7

There are no options in a BIOS related to ACPI or any kind of power related settings

I recently updated the BIOS (2 days ago) to the latest version using Windows 10, and I still can't install Windows 7 on this computer

How do I make the BIOS ACPI compliant and install Windows 7?

Two comments ...

First, read through this thread -- the comments mention that the motherboard site says this supports only Win10, not Win7:  https://community.amd.com/thread/240176

Second, forcing Win7 onto any PC these days is a really BAD idea -- for the following reasons.

1) Vulnerability -- MS has terminated support for Win7, meaning that they are not going to be issuing any more security updates. Thus, when new malware comes out (and it will), MS is not going to update Win7 to protect it. You must be running third-party Antivirus products or, if you PC is connect to the Internet, is IS going to get infected!

2) Drivers -- desktops not so much, but laptops especially, require custom drivers from HP to fully utilize all the hardware. HP does not provide Win8 drivers for new equipment. Without those drivers, your hardware is not going to function completely -- because the generic drivers provided by Microsoft only provide the most basic functionality.

3) Applications -- with the demise of Win7 support, application providers are going to stop providing updates for their applications for Win7. They will be focusing their new efforts on Win10. If you continue to run the Win7 versions of apps, you will be missing out on new features provided in the Win10 versions.

4) Hardware -- while much of the new hardware today still includes drivers for Win7, that is going to end and in short order, the only drivers included with new hardware will be for Win10. That means if you want to update or expand your Win7 PC with new hardware, that is going to be increasingly difficult to do.

If that's the case what does the "Compatibilty mode" option mean in the BIOS? It's description says it is to support legacy OS like Windows 7. What is the Compatibility Support Module?

Not a BIOS expert -- so I don't know.
