That reported disk size is the size of the partition where Ubuntu is installed, not of the entire drive.
To see all partitions, open the Terminal using Ctrl+Alt+T and type lsblk. You will see something like this:
$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdc 8:32 0 119.2G 0 disk
├─sdc2 8:34 0 58.6G 0 part
├─sdc3 8:35 0 29.3G 0 part /
└─sdc4 8:36 0 7.8G 0 part [SWAP]
sdd 8:48 1 29.8G 0 disk
├─sdd1 8:49 1 1.5G 0 part /media/rick/Ubuntu 17.04 amd64
└─sdd2 8:50 1 2.3M 0 part
sr0 11:0 1 1024M 0 rom
This Ubuntu 16.04 system is on sdc3 and shows up as 29.3G. But the drive itself is 120GB.
In this example, sdc is 120 GB drive that shows up as 119.2G in Gigabytes. Of this sdc2 is partition 1 (Windows) of 58.6G, sdc3 is partition 2 (Ubuntu) of 29.3G and sdc4 is partition 3 (Linux swap) of 7.8G.
In your case, you should find that your Ubuntu partition (mounted on /) shows up as 25.9G
