My Ubuntu freeze during the upgrade of 15 to 16, now he does not want to start again. after the loading screen it stops at a black screen and does nothing. I tried this tutorial http://ubuntuforums.org/showthread.php?t=2217829 replacing RO for RW but it stop in other black screen.
Can someone help me to at least recover my files?
Do you hear the login dialog sound while the black screen?
If yes:
If not:
If the upgrade froze the files in your home directory should not be touched.
So a way could be:
First:
Restart the installation process (you should backup your home directory before the reinstallation).
Second:
Check if all your files in the home directory are still there.
If not, Restore your files from the backup you made in the last step.
