How do I extend the partition size of /dev/sda5 by merging it with unallocated space of 20.0GB
EDIT:
When I try to create a new partition(using the unallocated space) I get the following error
It is not possible to create more than 4 primary partitions
Since the space is not allocated, are you prohibited from right-clicking on /dev/sda3 and selecting resize? You could also left-click into the /dev/sda3 space and then click the right-arrow that will illuminate (third from the left).
You should be able to resize and then click on the check to 'apply' changes.
