I have a problem after i tried install a OS(Debian) on a USB device. Now if i start the ps, only the rescue mode of grub starts.
I tried to run some commands which i found in the web but it don't work as i want it.
The commands where like ls, but it allways says: "Filesystem is unknown". I don't have any idea to do right now. Please help me!
I have a Notebook with a SSD and a HDD.
