But I think the video above is a great demo. It's a complete walk-through of where to download the OS up to installation.
I already have my 8GB USB drive burnt with the CloudReady Chrome OS. If you like the concept of Chrome OS and would like to try out a live USB version, watch the video above.
Btw, the live USB can install to SSD or HDD, but be careful and backup everything before doing this, as it erases the drives completely.
Sorry, no dual-boot yet.
