How to Remove the Windows Recovery Partition

Normally the steps to delete a partition are as follows:

1. Right-click the Start button.
2. Click Disk Management.
3. Right-click the partition you wish to delete,
4. Choose Delete Volume.
5. Select Yes when warned that all data will be deleted.

Unfortunately this doesn’t work for Windows Recovery partitions. The Windows Recovery partitions are protected and so right clicking on them has no effect at all.

To delete the recovery partition follow these steps:

1. Right click on the Start button.
2. Click Command Prompt (Admin).
3. Type diskpart.
4. Type list disk.
5. A list of disks will be displayed. Note the number of the disk which has the partition you wish to remove. (If in doubt open disk management and look there, see steps above).
6. Type select disk n(Replace n with the disk number with the partition you wish to remove).
7. Type list partition.
8. A list of partitions will be displayed and hopefully you should see one called Recovery and it is the same size as the one you wish to remove.
9. Type select partition n(Replace n with the partition you wish to delete).
10. Type delete partition override.
11. The recovery partition will now be deleted.
