I am in the process of reinstalling Ubuntu. When I got to this step:

Ubuntu Partitioning

I was prompted to choose a logical or a primary partition. I've never seen this dialog box before -- before it just told me to choose the mount point and the format.

Should I choose logical or primary? The default is logical.


The short answer "it does not matter much".

MBR partitioning scheme allows you to have up to 4 partitions on a drive, one of those partitions can be an "extended partition", which acts as a container for any number of "logical partitions". The partitions which are not inside the extended partition are called "primary partitions".

There's no difference in how they function or anything. So, if you don't have specific reasons, just go with the default choice.

  • Thanks! Currently partitioning and I used the defaults. I'll see how it goes. – Emerson Hsieh Apr 12 '12 at 0:48

    FWIW, when I get a new drive, I usually create one big extended partition, with no primary partitions at all. This give full freedom to create as many logical partitions as I need, and to resize any partitions in the future without too much fuss. I've never had a problem doing it this way with any OS. – Marty Fried May 1 '12 at 18:45
