I had cooked the Acer netbook trying to load stupid Ubuntu Linux.
I just got Chromium OS to run on the Acer netbook. It does not appear to be installed but runs from the thumb drive.
I followed instructions on lifehacker.com and downloaded a vanilla build from Hexxah. I have no idea what I'm talking about.
This included running Image Writer for Windows. This utility supposedly writes the unzipped image of the vanilla build onto a thumb drive. Unfortunately, it gives the impression that it has killed the thumb drive, which does a very convincing job of playing dead by making Windows think it needs to be formatted.
As you can imagine I repeated these steps many times with several different types of failures before I finally decided with no real expectation for success to simply put the dead thumb drive into the Acer and turn it on. To my amazement Chromium OS came alive. However, it gave no indication that I could choose to install it.
This is further than I got with stupid Ubuntu.
