The public debut of Google Chrome OS today has the press abuzz over the potential of the new web-based operating system. And now that it's open sourced, you have the chance to try it out for yourself. Unfortunately, most people aren't ready to undertake the daunting task of actually taking Google's recently open-sourced code and turning that into a bootable computer. So we've put together a step-by-step guide to doing this, for free, in around 15 minutes (depending on how long it takes to download the OS itself). No, this won't get your computer booting Chrome OS natively (and frankly, you probably wouldn't want to yet anyway). But it will get it up and running in a virtual machine using the free software VirtualBox, which is available for Macs, PCs, and Linux. First, a few caveats: we didn't create the Chrome OS build ourselves — it was downloaded from BitTorrent. In theory it could possibly have been tweaked by some malicious hacker to steal your Google account information (this is unlikely, but who knows). There's an easy fix if you're worried though: just go make a throwaway Gmail account, and use that to play around with the OS. Also note that because this is running in a virtual machine, you're probably not going to be seeing great performance (like that 7 second boot time). But it's more than good enough to get a feel for the OS for yourself.
