I've been trying to increase the size of my /home partition. In most tutorials there is an extended partition already available but I can't find one in my system. I have configured my Ubuntu System to have very little storage and i would like to make it bigger so that it can actually be usable.

  • You have to remove some of the disk space off of your Windows partition and then allocate that space to /home. Be very careful when doing this. I highly recommend backing up all of your Windows data. – Gordster Mar 27 at 0:11

Note: This is why I don't recommend multi-partitioning Ubuntu, especially on a smallish disk.

Your /dev/sdb3 NTFS (C:) partition needs to be reduced by using Windows Disk Management application.

Your /dev/sdb5 (/) and /dev/sdb6 (/home) both need to be expanded using gparted.

Make sure that you have a good backup of your important Windows and Ubuntu files, as this procedure can corrupt or lose data.

Keep these things in mind:

  • always start the entire procedure with issuing a swapoff on any mounted swap partitions, and end the entire procedure with issuing a swapon on that same swap partition

  • a move is done by pointing the mouse pointer at the center of a partition and dragging it left/right with the hand cursor

  • a resize is done by dragging the left/right side of a partition to the left/right with the directional arrow cursor

  • if any partition can't be moved/resized graphically, you may have to manually enter the specific required numeric data (don't do this unless I instruct you to)

  • you begin any move/resize by right-clicking on the partition in the lower pane of the main window, and selecting the desired action from the popup menu, then finishing that action in the new move/resize window

Do the following...

Note: if the procedure doesn't work exactly as I outline, STOP immediately and DO NOT continue.

  • boot into Windows
  • start the Disk Management application
  • reduce /dev/sdb3 (C:) partition by the amount that you wish to add to /dev/sdb5 and /dev/sdb6. Probably around 50G.
    • Note: You may have to temporarily disable hibernation and page file to do this.
  • reboot Windows and confirm proper operation

  • boot to a Ubuntu Live DVD/USB, in "Try Ubuntu" mode
  • start gparted
  • move /dev/sdb5 partition all the way left
  • resize the right size of /dev/sdb5 and increase it by approximately 10G
  • move /dev/sdb6 partition all the way left
  • resize the right side of /dev/sdb6 all the way right, increasing it by approximately 40G
  • click the Apply icon
  • I'll try this thank you. If this doesn't work I'll try reinstalling ubuntu and allocate more space. – Iesa Muhammed yesterday

No, you will not have an Extended Partition because your system was formatted with a GUID Partition Table. When there are six non-extended partitions, it's GPT, not the old MBR which was first defined back in DOS days. https://www.howtogeek.com/193669/whats-the-difference-between-gpt-and-mbr-when-partitioning-a-drive/explains the difference.

Since changing the partition table is the easiest way to completely lose all your data, please make a backup first, and verify the destination of the backup (be it external drive or cloud) matches the source data. Then, repeat the backup to a different external drive or cloud and verify that.
