According to a Reddit thread, someone discovered an “Alt OS” references in a recent Chromium Gerrit commit, which could suggest Google might implement some sort of dual boot functionality in the Linux-based Chrome OS operating system for Chromebooks to allow users to install and boot multiple operating systems. The commit mentions the fact that it adds AltOS NVRAM flags to Chrome OS to enable or disable the “_alt_os_request” flag for an AltOS boot flow. Digging deeper into the said commit, it appears that there’s a reference about “go/vboot-windows,” which could suggest it might be possible to install Windows alongside Chrome OS.
