Windows tools only allow to extend a partition to the right.
As you have 4 partitions to the left of E: and one to the right
I would clean the drive, create a new partition and restore E: to the new partition.
or
You can delete the 4 partitions to the left of E: and create a new partition. Delete the partition to the right of E: and extend E: (easy task)
or
You can use a better disk manager like
Minitoll that allow you to extend a partition to the left using an unallocated space and also to the right using an unallocated space.
