Hi George, thank you for reading my entire post here.
Well, you've got a really nice and performing notebook, well done my friend.
Luckily, I had set with Seven Forum, that every new post here it will sends me an email in my inbox and occasionally I saw that you wrote me here.
In my notebook I have now installed 4 operating systems, of which I use all 4 for different reasons, I have installed:
Windows 7
Windows 10
Windows 11
Ubuntu / Linux
What can I say, if you want to install Windows 7, I recommend it, even if the support it is closed from Microsoft, because it is generally a lighter operating system than the new Windows, and from my simple tests I noticed that Windows 7 has slightly better performance.
Then, I also recommend it, because sometimes (if you are a person who "fiddles with" a lot of software) it might be useful to use it for compatibility with old software or games.
To make it work you need to prepare your Windows 7 Custom ISO.
We are lucky because the CPU / Motherboard model you have (it's the same as mine) is the last of the series that supports Windows 7 unofficially, but with custom drivers (at least the USB ports).
So, for my part I found all the official drivers and also all the software compatible with Windows 7, especially the MSI Center software for managing the fans etc ....
The only thing that it won't work for you is the Wifi / Bluetooth card hardware, but everything else will work for you, from the Chipset, Tunderbolt port, to the RGB keyboard, the Ethernet connection, and above all to the USB ports (with custom drivers).
The thing that was most important to me, that someone made special drivers for the USB ports. So if you want to install it, I have found all the solutions and if you want I can help you (memory permitting, because it's been a while since then).
For bluetooth and Wifi, I don't really need because I use my Notebook as a Desktop replacement, but if I really want to play some video game or connect anything Bluetooth or connect with Wifi, to solve this I found the solution, by buying a USB pendrive that will do the WIfi and Bluetooth together. Anyway, I'm here always with the hope that one day someone will be able to customize the drivers of the laptop's Wifi / Bluethooth hardware card.
Anyhow, I never will be tired to say Thanks to @
Vineet Garg for the help in the past, which was the key for me to be able to face many difficulties together...
