Problems installing Windows 7 on modern hardware, 0x0000007B BSOD

(Sorry if this post is a mess, I have had to retype this because even though it says it autosaves it doesen't actually work so when I closed my browser it was gone...)

Hello, I think this is the right section.

I have been trying to dual-boot Windows 7 and Windows 10 on my HP Pavillion Gaming PC (see profile for specs), but I have encountered some problems.

The first problem i encountered was that the installer would not recognise my mouse and keyboard, but that was easly solved by integrating the drivers using 7UPv64F (with simplix pack).

The second problem was that the installer would not recognise my M.2 NVMe SSD.
I discovered this post, and used the BOOT.WIM from SIW2's boot media in mine, and luckly it recognised my SSD and I was able to install Windows 7.

However, on the first boot of Windows 7, I got the dreaded 0x0000007B BSOD.
The install image does have the two NVMe hotfix updates, I checked this using NTLite.
I also tried to put the storage controller drivers from HP's website on a USB stick and integrating them using the Windows installer, but it wouldn't recognise my drivers.
I also tried integrating them with DISM++ in Windows PE, but for some reason it just ended up corrupting the image completly.

Any help solving this would be appreciated.

Can you provide us with the exact serial number(S/N) and exact product number(P/N) on your HP Pavilion Gaming PC so we can confirm its identity and locate its support site?
Your "My Computer" specs were not helpful in doing that.

Sure,

P/N: 7MX99EA#UUW
S/N: 8CG9375V44

According to that serial number and product number, you have THIS HP Pavilion 690-0050no Gaming Desktop which came with Windows 10 Home 64-bit.
You should add and save its support site in your browser's bookmarks list so you can quickly refer to it when needed.

THIS is the product specifications page which shows the hardware it came with.
It's a 9th generation Intel model and not designed to run Windows 7, so you can expect to have driver issues when using that operating system.

I've never run Windows 7 in a computer newer than 6th generation Intel, so I've never experienced driver issues similar to yours.
There are members here who are very knowledgeable in resolving Windows 7 driver issues in newer generation Intel computers, so be patient until some of them reply to you.
Good luck.

Win 7 doesn't have the drivers for the new driver so you have to add them to the Win 7 installation drive, specially SATA, USB3.x (that is why you don't have mouse and / or keyboard) and M.2 NVMe.
Update your Win 7 installation media.

Also your MB must allow you to set to CSM and disable secure boot and fast boot.
