I have a lot of important documents on my computer, and I guess I messed up my OS somehow because when I rebooted the computer, it took me to a console window with no GUI. I typed "startx", and it spat out a "no such file or directory" error: my favorite. I needed to copy the files to my USB drive, which I formatted to FAT32. I typed the command "lsblk" to list all the drives on my computer, and I see my USB drive listed. It just has no name. I'm a total idiot when it comes to anything Linux. I only know the basics. I named my USB drive "USB" in Windows, but when I type "cd /USB" on Linux, it spits out another "no such file or directory" error. I'm pretty sure I'm doing it wrong. It's really frustrating that I know my file is on my hard disk. I just can't figure out for the life of me how to copy it to my USB drive on Linux. I know how to do it on Windows but not on Linux.
I'm running Peppermint OS (which makes things worse since it's apparently obscure, and there are almost no tutorials on it, and the tutorials there are are way outdated).
That's all the information I have. Please be easy on me if I did a terrible job explaining my problem. I am Linux stupid.
