FIX: Cannot Delete Partition on Windows 10/8/7/Vista (Solved)
If you cannot delete a partition on Windows using the Disk Management utility because the "Delete Partition" option is greyed out, then probably the partition is an "EFI System" partition or a "Recovery Partition". These type of partitions (EFI & Recovery) are system protected partitions and for that reason they cannot be deleted by using the Windows Disk Management utility.
In this tutorial you will find detailed steps on how to remove partitions (including the system protected Partitions, EFI or Recovery) using the DISKPART utility. *
Caution: The System Protected Partitions on the main (OS) disk, should not be erased because your system will not be able to boot. The instructions below, shows how to delete partitions on a secondary disk, that cannot be deleted using the Disk Management tool.
How to Delete a Partition using DISKPART. (Windows 10/8/7/Vista)
Step 1. Open Command Prompt as Administrator.
1. At the search box type: command prompt or cmd
2. Right-click at Command Prompt result and select Run As Administrator.
Step 2. Delete Partitions with DISKPART.
1. At command prompt, open the DISKPART utility, by typing this command:
- diskpart
* Note: Press Enter after typing each command.
2. Then give this command to view the installed hard disks:
- list disk
3. Now select the disk that you want to remove the partition(s):
- select disk X
* Note: Replace the X with the number of the disk that contains the partition that you want to delete.
(e.g. if you want to delete all the partitions on Disk 1, the command will be: "select disk 1")
4. To view the partitions on the selected disk, type this command.
- list partition
5. Then, select the partition that you want to remove, with this command:
- select partition X
Note: Replace the X with the number of the partition that you want to delete.
(e.g. if you want to delete the partition 1, the command will be: "select partition 1")
6. Finally type the following command to delete the partition:
- delete partition override
7. If you have want to delete another partition (on the same disk), just select the partition (e.g. "select partition 2") and then give the "delete partition override" command to delete it.
8. When done, type exit to close the DISKPART utility.

someone put win 10 "over" vista. They are on separate partitions on a dell laptop. Neither the 134 GB primary that has vista, nor the extended partition that has win 10 will delete following the steps given. So I am stuck and computer runs like it is mud. Any suggestions?

I suggest to backup your files to another disk and to perform a clean Windows installation.

It only gives me only primary and when i say override it says dispart has encountered an error : the request could not be performed because of an I/O device error.
See the system Event log for more information.
