I'm trying to create a new partition on my boot disk but I get an error

would be an extended partition since I already have 4.

Can anyone help?

Sorry, but you are allowed only 4 primary partitions *including* the extended partition.
You will have to back up /dev/sda4 and delete it, then make the rest of the disk into the extended partition /dev/sda4.
Then you can create as many logical partitions (sda5, sda6, ...) as you wish inside the extended partition.
The extended partition itself is not mountable and does not contain data, only logical partitions.
