I ran GParted from the 'LiveCD' Shrank the large partition, created a new one, and saved the changes, but now running Ubuntu I can't see this partition.
What is my failing? Apologies if it's a bit of a basic mistake...
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 262GB 262GB primary ext4 boot
3 262GB 496GB 234GB primary ext2
2 496GB 500GB 4170MB extended
5 496GB 500GB 4170MB logical linux-swap(v1)
sudo parted -l
or a screenshot of gparted.
