Is this Windows 7?
You're at the limit of Primary partitions, you'll have to make an existing one a Logical partition. I would choose "E".
OR
What is Disk 0? Your old boot disk? You want to get the Recovery Partition moved over to Disk1, so delete "E", allocate Disk1 space as Primary, copy Recovery to new Primary space, then kill Disk 0.
This is all done easier with 3rd party software, AOMEI Partition Assistant or MiniTool Partition Wizard.
