I unlocked the bios and was able to install windows 7, formatted everything on the drive like an idiot. Now I want to go back to the Chrome OS because the new update is gonna make me feel less claustrophobic when using the laptop. Ive been lurking everywhere for the past 3 hours and haven't found anything (thats still intact) on how I would be able to acquire the normal updated OS while still retaining the unlocked BIOS. Any help would be greatly appreciated
