I just made 120 GB of unallocated space from my Windows 8 partition to put into my already existing Ubuntu home (sda7) partition.

The problem is when I try to create new partition from unallocated it says

It is not possible to create more than 4 primary partitions

All I want to do is put that free space into my Ubuntu (to sda7).

enter image description here

sda2 - Windows 8 drive C
sda3 - Windows 8 drive D

Edit: So I run "Try Ubuntu", unmounted all partitions, and resized /dev/sda4 so unallocated space is not below sda4. But when I try to resize /dev/sda7 (which I want) it only allows me to resize for 7Gb or so, not all 120Gb I need.

Seems to be the limit due to upgrade from windows to ubuntu-- where you already used up 4 primary partitions - only remedy is to backup data - re-install and this time use gparted to create required no of partitions/types.

I faced the same problem -- I used the same D: /E: drive from windows 10 installation - but formatted C: drive for ubuntu.

To put that 120 GB free space into Ubuntu ( /dev/sda7) partition,follow the below steps.

  • First you had to boot Ubuntu live disk.

  • Click on "try ubuntu" option on startup and then open gparted from Dash.Make sure that all your partitions are unmounted.

  • Right-click on the /dev/sda4 partition and then choose Resize/Move option to increase its size with the 120 GB unallocated space by dragging the left arrow to the extreme left.After resizing,apply the changes.

  • Now your 120 GB unallocated space will comes inside extended partition and just below to the /dev/sda7 partition.

  • Right-click on the /dev/sda7 partition and select Resize/Move option,now you can be able to add 120 GB unallocated space to your ext4 partition by dragging the right arrow to the extreme right.

  • Thank you! By the way is it possible to do that if I just reboot into Windows 8? – user1880405 Jan 25 '14 at 09:03
  • Boot ubuntu live disk and then do all the above steps,it will works. – Avinash Raj Jan 25 '14 at 09:40
  • Windows 8 doesn't know Linux partition format, So it can't resize it. As @AvinashRaj, use Ubuntu live CD or USB key. – user.dz Jan 25 '14 at 11:33
  • Sneetsher, thanks. Anyways I unmounted all partitions in Live ubuntu usb and now unallocated space is below sda4, which is good, but I cannot resize sda7 for some reason. It allows me resize only around 7Gb, and not all 120Gb. Any ideas? – user1880405 Jan 25 '14 at 15:12

  • did you see that your 120 GB unallocated space was at the top of extended partition.How did it goes to the top? – Avinash Raj Jan 25 '14 at 15:56
  • Because I increased extended partition's (sda4) size as you said in your answer at 3rd step, so it moved below, just like your 4th step says... – user1880405 Jan 25 '14 at 16:02
  • ok anyways you need to move the unallocated space just above to the `sda7` partition so that you can be add the space to your ubuntu sda7 partition for this see [case2](http://askubuntu.com/questions/178712/how-to-increase-swap-space/389067#389067) in my answer. – Avinash Raj Jan 25 '14 at 16:07
  • But unallocated space is in fact inside the extended partition, you case3 says exactly what I did and then it moved inside extended! – user1880405 Jan 25 '14 at 16:14
  • you can be able to add space to the partition only if the unallocated space present above or below the partition.So see my case2 to get down the unallocated space. – Avinash Raj Jan 25 '14 at 16:16
  • Now I understand what you are saying! Everything is solved, just strange that is't not possible to allocate to certain partition immediately. Thank you Avinash. – user1880405 Jan 25 '14 at 18:45
