Thank you very much for all of the info and links. Although it looks like the particular OS that you are talking about can be installed into a PC, the question would be why would anyone want to do it? That particular OS, CR OS Linux, has not been supported or upgraded in over 4 years according to the links that you provided and the info that I can read.

One would wonder if an OS that has not been worked on or upgraded in over 4 years is safe to run in 2017. This little limitation seems to me to be red flag that screams to avoid .
If I were in the market for a Chromium-like OS I would consider the NeverWare because it has current support and development.

Again, thank you for all of the info and links that you posted. It does appear that CR OS Linux can be run on a PC desktop, but why would anyone run an OS that has not had any updates for over 4 years?
