Question Contradictory Installation partitioner behavior:


While trying to make sense of Grub I solved one part of my confusion. The GUI Disk partitioner that comes with distro installers does not partition the drive like it displays even in manual mode. I think it is intentional by the install application but is confusing.The diagram from this screenshot is how I believed the hard drive would look when I was done but the chart says otherwise. I thought is was sort of interesting and that someone else might feel the same way.Check it out. I will master Grub God Damn it! This funky install application will not stop Me!

Can you explain where you see a discrepancy between the diagram and the chart?

It is creating two partitions, sda1 and sda2. Inside sda2 it has two logical partitions, sda5 and sda6. The remainder is unallocated.

I'm assuming this is to be a dual boot installation?

It goes from sda1 (which i did create)to sda2 (which I didn't manually create and skips logical volumes three and four and then creates the partition I wanted second to be fifth where Linux is on. Why did it create logical volumes for only three partitions including the swap? And it is a dual booter.

Only four primary partitions are allowed.
sda1 is an ntfs primary partition.
sda2 is an Extended partition which contains no data but is a container for logical partitions. Creating an Extended partition uses one of your primary partitions.
Logical partitions in Linux always start with number 5 so sda5 in this case.
sda3 and sda4 could be created and would be primary partitions.

I'm still not getting it.

I deleted all of the previous partitions. I installed Windows first. Second I installed Linux's swap and then the root partition. I should have one more partition to go before a logical drive is created. It's not the partitioning numbering I'm pointing out, it is that I should have three partitions and no logical drives. If I went through the process of creating more than four sections of the hard drive that the O.S's would keep separate why do I have more than three and hence logical volumes?

It is normal in Linux to make use of logical partitions within an (extended) primary partition, so as not to waste primary partitions. There is a limit of four primary partitions (as yancek pointed out earlier), so they are in short supply (particularly since some operating systems will run only from primary partitions).

If you look careful at the diagram you have attached, you will see a cyan border around sda5 and sda6; this is the extended primary partition sda2 that contains them (and why they are indented in the partition list). The extended partition sda2 is only a container.

When you create a partition in the partition manager, you can select whether you are creating a primary/extended/logical partition. So it can be set up however you want. The layout you have attached is a reasonable one.

Can we nail this down?

So this is Automated by the Distro installer then. The Distro installer is not actually manual but is a wizard of sorts and this is why Fedora ,Mandriva and Ubuntu are considered GUI partitioner Distros because it is automated and graphic. Open SuSe is not and hence has an actual manual partitioner and is not considered a GUI partitioner Distro?

Yes, it is a 'wizard' installation. However, when you select manual partitioning during the installation, you are able to make any changes inside the partitioner (gparted) that you want.

It is only the graphical nature that makes them a GUI, not the automation. Even the non-GUI installers tend to be 'wizard'-like. A number of distros allow you to choose between a GUI and non-GUI install, but the GUI itself is just to make it look a little more friendly.

The 'GUI' refers to the interface of the installer itself. As it happens, the GUI installers tend to use the GUI front-end gparted to parted to do partitioning, but this doesn't change the process of partitioning.
