I opened chrome and it didn't launch. I used the terminal to open it with sudo and got the message to use the --no-sandbox in addition to the main command. After I did that, the system became unstable and eventually crashed. It told me to log out, so I did, but nothing happened afterwards. Then I just hit the power button and the system turned off. After turning it back on, it tried to start up, but then started hanging with a simple message: /dev/sda5: clean, 35784/1974272 files, 7517253/7891712 blocks
. After a while, the laptop (yes, laptop) fan turned off and no changes. I hit Ctrl + Alt + Del
to restart and it did show the Ubuntu logo and said that it was restarting, but after restarting it was stuck at the same place.
No clue what to do now. I have a windows MAIN partition still available. I think that if I just reinstall the Ubuntu system it might work again but I don't know.
Help is very welcome as I have some big amounts (32 GB) of data on the Ubuntu partition.
