I do not understand this question.
Is there a reason you cannot install Linux ? Linux can be installed from a USB and should work on any system running windows 10.
If Linux is too heavy for your system, there is always NetBSD. I have NetBSD on an AMD 300MHz (= PII) with 512 MB memory and it runs fine.
Funny I actually got an old netbook maxes out 2GB of ram, 32 bit, probably looking at some kind of Debian with i3-wm
I got it for nostalgia, the physical design of the laptop even though it's a thique brick
That was basically my question – why install ChromeOS instead of a light Linux distro?
