I installed by mistake two primary Ubuntu partitions on dual booting PC (64-bit) with Windows 7 and Ubuntu 12.04. First I tried Someting Else when installing Ubuntu 12.04, then I changed my mind and installed Ubuntu 12.04 without defining partition. I have about 1TB available for Windows 7, PC starts from Ubuntu as default. Result was two primary partitions in Ubuntu, 890 GB and 16 GB. Ubuntu OS resides in partition 16 GB. Then I installed software OpenFoam and it was installed in partition 890 GB. I cannot use it as it stands.
What would you advice? Reinstall Ubuntu? Use GParted ? I already have a boot CD for GParted.
