Topic: [Resolved]Can't select logical partition

Hello everybody,

Here is a screenshot from gparted
http://img97.xooimage.com/views/f/7/9/s … c422e.png/

I want to use the unallocated space as a logical partition. But when i want to create a new partition from this space only "primary partition" is selectable, others choices are disabled (greyed).

I tried with a gparted boot cd, with same result (only difference is the key lock icon not appearing from gparted boot cd)

Has anyone an idea about this stuff ?

Thanks

Re: [Resolved]Can't select logical partition

The key means that the partition is actually in use, so GParted can't modify it.
It seems that you use GParted from within some Linux distribution (Ubuntu? ).
To have the partitions free to modify, you have to unmount them.
If you can't do it with the running system's partitions, you can use the GParted live (cd or usb stick). It doesn't mount any partition by default, so you can work on them.

On the problem:
You already have an extended partition /dev/sda3 (the light cyan border). Its space is entirely occuped by the logical /dev/sda5 (the dark border inside the cyan one).
The free space is located out of the extended partition. So, you can either make a new primary partition (you have already 3), or expand /dev/sda3.
In the second case, you will have the free space in the extended partition, and then you can make a new logical (/dev/sda6) or grow the existing /dev/sda5, according to your needs.

*** It is highly recommended to backup any important files before doing resize/move operations. ***

Thanks, you are right it was necessary to extend the extended partition before creating a logical partition. Done !
