Thank you for the welcome, Magic B. Okay: I got Trisquel Mini partitioned successfully! Huzzah!
The OS loaded from a burned disk nice as you please, thank you very much Ishmael. (It took some time on the old Inspiron 1520, but it did the job.)
One hiccup: after install I could not get a network connection. So I will scour the forums and see what that is about.
Again, thanks for the help! - Zem
