Allocating entire hard drive to Linux Lite

[mathewalex]

Had the same problem, and solved it as below -

Step 1: Deleted the "unused" partition using GParted

Step 2: Clicked on the Linux partition to "grow" and selected Resize/Move. Now the next step (pop-up window) showed as follows -

                      Free space preceding (MiB) = 0 (default)
                      New size (MiB) = XXXXX        (This is the partition to increase the size of)
                      Free space following (MiB) = YYYYY (This is the "unused", now deleted, partition)
                      Align to = MiB (default)

Just make the value for "YYYYY" = 0 and apply the operation(s).

At the end of all operation(s) "XXXXX" becomes a single partition increased to "XXXXX+YYYYY" size.
