Ubuntu: Unable to resize partition through Gparted


I tried to resize it but it the slide bar wont even move. It's not mounted and I cant boot into windows because Lenovo screen pops up then goes black then switches to Ubuntu. I need more memory for my Ubuntu.

My partitions


If you are trying to shrink sda3, which has an exclamation mark beside it, then you need to ensure that Windows was properly shut down first. You can see more details in GParted by selecting the partition and using the Partition -> Information menu option.

If Windows doesn't boot, then you might need to boot from Windows Install / Recovery media and run chkdsk /f /r on sda3 (or likely C: in Windows).


First, you'll need to get Windows to properly boot up using a Windows install/repair disc.

note: You don't need "more memory for my Ubuntu", you need "more disk space for Ubuntu".

To make more room for Ubuntu, you'll need to shrink your Windows C: drive, partition /dev/sda3. You'll want to boot into Windows and use Windows own Disk Management application to do that.

Then you can boot a Ubuntu Live DVD and use gparted to do the rest of the work.

Backup your important data first, as partition manipulation can corrupt or loose data. You've been warned.

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 part of the main window, and selecting the desired action from the popup menu, then finishing that action in the new move/resize window

So do this... short answer...

After shrinking your Windows partition, boot the Ubuntu Live DVD...

  • swapoff on sda8
  • move sda8 partition all the way left
  • resize the left side of the sda9 partition all the way left
  • swapon on sda8


I had the same problem. Try running the machine from a USB with live session.

First at all be sure that Windows is completely shutted down, not hibernated, and that your data is backed up. Dowload Ubuntu or Linux Mint iso image. First erase you usb, and then burn using dd (its a easy way).

sudo umount /dev/sdX && sudo mkfs /dev/sdX  sudo dd if=/path/to/ubuntu_or_lm.iso of=/dev/sdX --status=progress  

When it finish, you are ready to reboot from usb. In the live session, open a terminal and run gparted with elevated privileges sudo gparted and just resize the partition.
