I have a Windows 7 and Ubuntu dual-boot; I am trying to extend my Ubuntu partition with approximately 20 more GB from the /sda3 disk (my D: disk on Windows) using GParted from a live USB. /sda4 is my Ubuntu partition. I have tried resizing etc. but apparently I am not able to extend /sda4 or /sda5. How could I go about this? Is there any way to extend my Linux partition or would I have to delete everything and install Ubuntu again? Side-note: if I press "New" I get an error message saying "It is not possible to create more than 4 primary partitions".
We could shrink a partition either form left or the right, but if we are to merge that unallocated space to another partition, unallocated space need to be on the right side.
- As you use MBR partition scheme, you can't have more than 4 primary partitions.
/dev/sda4is the right most primary partition, there isn't much you could do. (LVM addresses such matters though)
That's why it is recommended to have a separate
/home partition in case you want to reinstall.
- You should not use Window's Disk Management tool to shrink/create partitions, as it could convert it to a dynamic disk.
