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.
Note: This is why I don't recommend multi-partitioning Ubuntu, especially on a smallish disk.
/dev/sdb3 NTFS (C:) partition needs to be reduced by using Windows
Disk Management application.
/dev/sdb5 (/) and
/dev/sdb6 (/home) both need to be expanded using
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
swapoffon any mounted swap partitions, and end the entire procedure with issuing a
swaponon 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
/dev/sdb3(C:) partition by the amount that you wish to add to
/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
/dev/sdb5partition all the way left
- resize the right size of
/dev/sdb5and increase it by approximately 10G
/dev/sdb6partition all the way left
- resize the right side of
/dev/sdb6all the way right, increasing it by approximately 40G
- click the Apply icon
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.
