what is the oldest Windows OS that I could install on a Lenovo IdeaPad Gaming 3 15ARH05?

[Sergiaws]

I have that computer, and I wish to install Windows Vista/7 but seems to be difficult to get drivers.

Without really reviewing the hardware too carefully, I'd say Windows 7 is probably the oldest you could potentially install on your laptop. Even though Windows Vista is part of the NT6.x line, I almost consider it to share more traits with Windows XP since a lot of things were cut off from Vista when they were with XP. That's the problem with laptops and ultra small form factor PCs though, you can't really customize your hardware and even if you had a few options from the vendor when picking out your configuration, it's iffy if things like your wireless adapter or graphics adapter will work. Generally audio works without too much of a hitch.

If you could post a list of your hardware such as graphics, audio, wireless/wired network adaptor, and chipset...we could probably make a better determination.

firstly, I'll make three groups. In the first group, I'll include the devices which I must be able to use in Windows Vista/7. The second will have additional devices, and the third group will contain additional devices which I don't use.

the first group includes:

chipset:

In the third group I'll include the graphic card (NVIDIA GForce GTX 1650), I don't need it cause I'm totally blind, and Windows can even work without the graphic driver.
