I'm looking to increase the the size of extended partition from the unallocated free space.

Current size of extended partition: 42.7GB Unallocated Free Space available: 94.5GB

How can I use the Unallocated Free Space available: 94.5GB to increase the size of extended partition?

I assume that you are using Ubuntu flavor and you want to extend the logical partition that to be you are trying to resize or extend the vhd's/sdd on the physical or virtual machine box, if in case my assumption is correct please use the resizepart argument with parted.

Note: Do not forgot to take the data backup when performing it.

enter image description here

And there is another tool called gparted, to resize the partition on linux.


Using Gparted from a live CD could be the best solution. I for instance to resize an extended LBA partition I used Gparted as following:

  1. First Download a linux Live CD. "I used Ubuntu Mate live CD".
  2. Boot your Computer from the Live CD.
  3. From the menu->system menu-> Gparted.
  4. Look for partitions with a key icon left to the partition name and umount it right click. for the swap partition right click and no swap.
  5. Now I think you will be able to move and resize the extended partition. If any questions do not hesitate to ask



There cannot be an active partition to the right of the extended partion you want to resize to include the unallocated space.
