I'm trying to make my Windows partition bigger so I made my Ubuntu partition 150 GBs smaller. Now when I try to resize my Windows partition it won't go bigger -- it only gives me the option to make it smaller. How do I enlarge my partition?

To resize your /dev/sda2 partition, you have to boot from Ubuntu live disk or gparted live disk.

  • Boot from Ubuntu live disk.

  • Open gparted partition editor from dash. If gparted is not installed by default then install it by running sudo apt-get update && sudo apt-get install gparted command on terminal(Ctrl+Alt+T).

  • Make sure that all the partitions are unmounted before trying to resize.

  • Now right-click on /dev/sda3 and select resize option. Move the dragger to the extreme right so that 150 GB of unallocated space would comes before /dev/sda3 partition.

  • After that, you can be able to resize your /dev/sda2 Windows partition.

  • Would a gparted live usb work – user273348 May 15 '14 at 2:20

You just cant do it without having newly boot and do partition preferable during installation time . resizing partition may be allowed by some third party software but its going to harm your computer hard-disk. or if you join two partition or devide into two partition may be your system file will be corrupted and you will be unable to browse over windows or ubuntu . neither you can use kde partition manager and kvpm ,this will be avilable in ubuntu software center. or for in case windows you can use many third party software avilable
