I follow the tutorial but when i enter: mount /dev/sdb2 /mnt/usb
the output is: mount special device /dev/sdb2 does not exist

The problem people are facing is that "sdb2" was the usb drive in my case, It might be something else in your case.. Like sdb4, It's like a numbering and naming system.

You just have to pick the correct name of your drive that's all
