I re-partitioned my Windows 10 (1TB), installed along side Ubuntu and allocated(40GB).

Now I would like to increase the size of my Ubuntu from 40GB => 200GB ?

FYI: Already installed gparted. Confused on what to do now.

    Use Windows tools to shrink the NTFS partition. While gparted often works, some have had issues. If you use Windows then any issues are Windows only. Reboot into Windows so it can run chkdsk which is required after any resize. Then use gparted. You can either move / , your sda6 left & expand right or probably better create new partition and use as /home. Be sure to have good backups before anything else. https://help.ubuntu.com/community/Partitioning/Home/Moving – oldfred Jul 02 '19 at 20:01
  • That seems kind impossible given your actual partition scheme. You would have to resize your windows partition and then move your linux partition, and the resize it... But you would surely end with a broken system. – schrodingerscatcuriosity Jul 02 '19 at 20:02
  • First you'll need to create free space, i.e. shrink your windows partition. Then you can use that for Linux. I'd suggest doing the shrinking from within Windows and maybe not add the new space to your exiting partition but rather make it a separate home partition and move the old home there. – FelixJN Jul 02 '19 at 20:02
  • Boot from a Live USB - you cannot resize partitions when they're mounted (and booting from them mounts them) – waltinator Jul 02 '19 at 20:18

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

This is a two part process. Resize the Windows NTFS partition, and move/resize the Ubuntu partition.

In Windows...

  • temporarily disable the pagefile using the System control panel
  • reboot
  • defrag
  • use the Disk Management app to resize the Windows NTFS C: partition
  • open a CMD (command) terminal with admin privs
  • issue a chkdsk /f C: and confirm to do this on next reboot
  • reboot, observe chkdsk running
  • reboot and confirm that Windows still boots
  • re-enable the pagefile
  • reboot and confirm that Windows still boots

For Ubuntu...

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 to a Ubuntu Live DVD/USB
  • start gparted
  • move /dev/sda6 partition all the way left
  • resize the right side of /dev/sda6 all the way right
  • click the Apply icon
  • reboot
