If you want to use Chromium OS on your desktop PC or laptop, you can download the new ChromX version from Arne Exton’s website, write it on a USB flash drive or CD/DVD disc and use it live, directly from the bootable medium. However, if you decide to install it, please note that it can’t be installed alongside (dual-boot) another OS. Yes, you’re reading it right. You won’t be able to keep your current Linux or Windows operating system and also install this Chromium OS version, unless you install it separately on a second disk drive. The OS is designed to occupy the entire disk and not be installed on a separate partition.
