Here's my problem.
I have all 4 possible primary partitions, but I want to install another Linux distribution alongside.
Is there any way of doing this?

Yes, there is. You'd have to delete one of the primary partitions, which will make it possible to create lots of logical ones.

Where are you going to get the space from? Moving partitions can be a long process.

It would be relatively easy to remove your swap which will break you boot. then you can shrink your /home partition if you have space. then create the extended partition, add new partition and swap. To repair your boot you will have to edit fstab with the new UUID for swap. If any other partitions get renumbered or new UUID's you may also have to edit those in fstab and in grub.
to see new UUID
sudo blkid

On second thought it may be easier just to back up /home and reinstall with the new partitions defined first.

You cannot share /home with other distributions but can mount and share data partitions. If you want the same data you should create a data partition also. I have all my data several data partitions and now my /home is only 1GB. Some data is in NTFS for windows sharing and some in ext3 for linux sharing.

you could unmount your swap, remove the partition then shrink your windows partition and create a logical partition in the free space.

I have HUNDREDS of free gigabytes on /home
I'm going to:


Remove swap
Shrink /home
Make logical partitions in free space
Remake swap and new OS partition as logical

that's basically the same thing.
just remember, if you want to install another windows os, it most probably doesn't like being in a logical parition.
