I had a stable Ubuntu 14.04. It was automatically suggested to update the newer version. I started it, then after 1 hour it stopped, unfortonutly I don't remember the fail message, but it was in the Terminal and at the end it was an OK I pressed the power button once, shortly (It was a a huge huge mistake) The computer swictched off. I tried to switch it on, but after booting it has a black screen and nothning on it. I waited for 5 minutes. nothing happened. I pressed the power button shortly, once and it was written in a linux way font letters: Plymouth-poweroff .service [ OK ] started show plymouth power off scree... ok stopped cups scheduler .
. . . . . I am sad about my files on my computer. I haven't got a safety copy. Can anybody help me?
Thank you!
