As you can see from the screenshot on the Show your desktop thread, I am running Windows 7 on my HP Laptop 17 Series.
But how? This is a guide, and I'll show you how.
Firstly get k4sumi (r3tard)'s Windows 7 Updated v4 iso from here: https://board.eclipse.cx/viewtopic.php?t=401
YOU MUST BE DUALBOOTING WITH WINDOWS 8.0 OR LATER!
Install your newer OS first, then install Windows 7 onto another partition. Now, boot into your newer OS and replace this file:
/windows/System32/drivers/acpi.sys
with this:

or else you are stuck on a BSOD loop!
then setup Windows 7 like you would.
Now let's get the drivers.
For ethernet download this and install it via device manager: https://cdn.discordapp.com/attachments/982809497254920264/1049819539203956736/Realtek_Ethernet.zip
For graphics download the Win7/8.1 Ryzen APU driver (DOWNLOAD 21.11.1): https://winraid.level1techs.com/t/solution-win-7-win8-1-x64-ryzen-apu-video-driver/34203/1
Once you've done those two, the rest can be installed with Snappy Driver Installer Origin here: https://www.glenn.delahoy.com/snappy-driver-installer-origin/
I didn't include the trackpad driver because I use a USB mouse. But that might be in Snappy Driver Installer.
