Stuck at "/dev/sdb2 clean", no GUI

Ok so you are able to boot your normal system and change to a different console using CTRL+ALT+F2 ?
If that is the case then:

  1. Perform this command right after booted in your normal system and changed to a different text console:
    journalctl --boot 0 --no-pager > ~/lastlog.txt
    
  2. Boot using your Live-USB, and post the contents of lastlog.txt, which will be located inside your /home directory of your normal system.
    Use a codeblock for output formating as explained in: [HowTo] Post command output and file content as formatted text

Note you have to mount your /home partition from your normal system somewhere before you can access this file.
For example using:

  • systemd-mount /dev/sdXXX /tmp/home_partition
    
    Where /dev/sdXXX means your /home partition of your normal Linux install.

After the above command from the live-USB, your output can be accessed as /tmp/home_partition/YOUR_USERNAME/lastlog.txt.
Where YOUR_USERNAME is obviously the username you use to login into your normal Linux system, which you need to change in the above command.


PS:
Because you are able to boot and change to a different console, i will rename the topic to prevent confusions about your problem.


To copy the contents of text files you can make use of the xclip command, which you might need to install first.
For example, the below command will copy the contents of somefile.txt into your clipboard, which you then can use to paste in the forum:

cat somefile.txt | xclip -selection clipboard
  • Handy alias to use: alias xc=‘xclip -selection clipboard’
    Using this alias you can perform | xc instead of | xclip …
