When using a disk with an MSDOS partition table (as opposed to GPT) you are limited to a maximum of 4 primary partitions (or 3 primary plus one extended logical). You have used all 4 so you cannot create any more partitions. If you want to install a Linux system you will need to review which partitions are used for what purpose and delete some - though be careful because your Windows system and data live on at least some of them.
