Hello. I recently bought a laptop (12/20/2017) a new one of course. But yesterday, during normal use, there was an update that I could not influence. After which the computer had to restart. just like every time at the beginning, the inscription Lenovo appeared, when the dots were spinning and was to turn on, the system pops up first "attempting to recover the installation" and then "restoring the previous version of Windows". The laptop turns off and everything starts again. Unfortunately I did not back up. Nor a restore point. The laptop is under warranty, so you shouldn't worry, but it seems to me that the system is the cause and I would not want to lose the guarantee at the very beginning. I would ask for help because for now I only have an idea to inadvertently damage it.
