I have a Toshiba wish I replaced the windows 7 hdd with an ssd; I also replaced my dvd drive with another ssd. I managed to use ubuntu 16.xx two years ago, and always managed to upgrade....but I suspect that my second ssd (the dvd drive) still remains 16.04.
Now that I have downloaded 18.04, how can I fresh install it on all the disks?
Thanks in advance to anyone.
