I think there is a partition in my drive and I can’t find my OS backup, what should I do?

You can create a recovery USB drive by using the method on the link below or you could power wash the Chrome device, which usually does the same thing. Im not sure how much hard drive space your Chromebook came with, but it’s usually around 20 to 32gb. https://support.ctl.net/hc/en-us/article
