Did the Integrity Check Pass? I would have checked that first, and that is why I presented it first. A drive test takes time, the Integrity Test takes minutes.
The most important, or first thing we do is check the iso download was good using the "Checksum", and the iso was complete with no damaged or incomplete files. Then one can do the Integrity Check also, I only mentioned Integrity Test because you already had the medium created and installed, which is less complicated for some newbies than checking the iso Checksum.
Method of Installation had not been mentioned as this started out being a UFW Thread. If you want you can add method of Installation if you think that will help.
Where is your iso stored, on Windows or Linux, we can check the iso if you think it is needed, that is the first thing I do when encountering strange problems. Actually, some of us check it upon download with a download manager. Use this for your next download: Down Them All
