I installed Ubuntu 12.04 with no partitions. System created:
/dev/sda1ext4with 228GB/dev/sda2;extendedwith 4GB/dev/sda5;linux swapwith 4GB
I'm using GParted to make a partition in the 228GB (where Ubuntu is). However, it doesn't allow me to create further partitions. How do I create further partitions?
