How to remove a "hidden" partition that Windows will not touch

This basic process will work with just one drive in the system, but I am writing these directions targeted to those who want to remove partitions from a second drive. Usually when such a partition exists on the only drive in the system it has a purpose and should not be removed.

1. Attach the drive with the unwanted partition to an existing system and make certain it is recognized in the Disk Manager.
   
2. Go to the run window. In Vista and Windows 7 just click the start button, in Windows XP click Start / Run.
   
3. Type diskpart and press Enter.
   
4. Type list disk and press Enter.
   
5. Select the disk containing the “inaccessible” partition by typing select disk x, where x is the number of the disk, and press Enter.
   
6. Once the disk is selected, type list partition and press Enter.
   
7. Select the “inaccessible” partition by typing select partition x, where x is the number of the partition, and press Enter.
   
8. Type delete partition override and press Enter.

That's it. Go back to Disk Manager and you will see that the partition no longer exists.
