Chromebooks have always been great when you can work with web apps (and now including Android and Linux apps). But most people still have a separate Windows machine for specific tasks. This could change soon.
The "AltOS" feature was first released in April in Chrome OS. These initial commits revealed the Windows support, which convinced us that Google should let users launch both Windows and Chrome OS on the same computer. All previous commits refer to "Eve", the code name of the motherboard of Pixelbook.
The next round of commits was released in September. This gave us the icon that can be used when booting the Chromebook under a different operating system, as well as some keyboard shortcuts that the user must press to start the alternate operating system. It is not clear if these key combinations are for Google's internal testing only, or if they will survive until the feature is available on endpoints.
That brings us today. It seems Google is continuing to work so that Chromebook users can install Windows 1
The last round of Commit also mentions how the Trusted Platform Module (TPM) will handle multiple operating systems without compromising security even though no real user information is available. The end user does not have to worry about it anyway, but there are important steps to make sure that dual booting works properly and safely.
Currently it seems that Google is only testing this feature – codenamed "Campfire" and probably officially called "Dual Boot" – on the Pixelbook. There is a precedent for new features that are first available on Google's own devices. Google has offered other features such as Pixel Assistant's Google Assistant integration before it's available for other Chromebooks.
Of course, in the past you may have been able to boot Windows and Chrome OS with two boats, but it was a hacker at best, and installing custom firmware was included. This newer method probably only requires switching in the Settings menu.
If we see that dual booting with Windows is coming to the pixelbook soon, it will not be possible to tell when (or if) the feature will appear on other Chromebooks. When the Android and Linux app was launched, some reasonably modern Chromebooks were not used because they used an old kernel version. There is a possibility that this also happens with the support of Windows.
