I bought this chromebook 2 years ago, and for a chromebook it was quite expensive ($500). Just the other night, it went black and up popped the message in the photo. I need to reinstall the operating system. I cannot get to any other screen or use it any further until I reinstall. This requires using another computer which I do not have. I am very disappointed as it looks like I am going to have to buy another computer. Any advice out there?
