How to install Chrome OS from a USB drive

Can't wait for a new system running the final version of Google's OS? Here's a way to run Chrome natively today.

Have you already tried Chrome OS using a virtual machine, and were less than impressed? Well now you can get a feel for how Google's Web-centric operating system will run natively on your machine. The folks over at Engadget were able to boot Chromium OS -- the open source version of what will become Chrome OS -- off of a USB stick on a Dell Vostro A90 netbook. The USB bootable disc is based on the Chromium OS build of Twitter user Hexxeh, who set up a Web site where you can view all the instructions you need for getting your bootable USB up and running.

If you're ready to get your hands dirty and try out the new OS, here's what you need to know:

Get the Torrent

Before you do anything, you're going to need to download the Hexxeh's Chromium OS build. You can find a torrent link on Hexxeh's Website or you can use the mirror links found here and here courtesy of Engadget.

Set Up Your USB Stick

Hexxeh has some easy instructions for writing your Chromium OS image onto a USB stick. The instructions for Windows and Linux look pretty straightforward, but Mac users are going to have a slightly more complicated time.

Pick Your Machine

A major problem with Chromium OS right now is that its device drivers are in the very early stages of development. That means some parts of your computer may not respond when using Chromium OS. One of the most common problems being reported is the lack of Wi-Fi functionality. So you may have to use an Ethernet connection instead. You should also know there's no guarantee the OS will boot up at all.

If you're in the market for a netbook or laptop, and you plan on experimenting with Chromium, check out Google's list of devices that are known to work with the latest version of Chromium OS. The list is primarily for developers who want to work with the new OS, but there's no reason you can't use it as a buying guide. The device index features a sortable checklist that lets you know if the Wi-Fi and trackpad functions are working, as well as general comments and warnings specific to each device.

For example, you might want to stay away from the Asus Eee PC 900 if you plan to run Chrome right now. The netbook's Wi-Fi is supposed to work, but the device's fans may not run, which could cause your system to overheat. Other Wi-Fi-ready devices, according to Google's list, are the Toshiba mini NB205, and the Asus Eee PC 1008HA. The Lenovo ThinkPad T400 may also work after upgrading the Wi-Fi firmware. But before you go out and spend money on a new computer, read over Google's hardware list to make sure you are fully aware of the functionality and problems for the device you have in mind.

Booting From the USB

Once you've got your computer, and have gone through the steps of writing your bootable disc, you may find you can't get Chromium OS to boot on your Windows-based machine. If this happens, you may have to change the settings for how your machine boots up.

You can learn how to change the settings by checking out PC World's guide to installing Windows 7 on a netbook using a USB drive. The instructions are not Chromium-specific, but you should be able to figure out how to adapt this method for your purposes.

A word of warning: Changing the boot order means messing with your system's command prompt and BIOS. If that sounds scary, you might be better off picking up an official Chrome OS machine later next year. For the rest of you, let us know in the comments how Chromium is running on your netbook.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
