sda7 is my /home (Linux Mint) that I want to merge with sda8 (which I cut out of Windows). I read here that I can't combine two partitions that are not adjacent and that they can't be both extended. Is this true? If so, should I convert one of them into something else? I have no option to drag any of them with a mouse.
Here's a high-level overview for how to get some unallocated space you can use for sda7.
- Get the contents of sda8 and add them into sda7.
- Delete sda8.
- In the unallocated space where sda8 was, create a new Linux swap partition; The same size as the one you already have.
- Delete the "old" Linux swap partition, sda6.
That should allow you to drag sda5 and sda7 to the left, freeing up space after sda7. Then you can extend sda7 to consume the remaining free space.
