How do I delete an OEM Partition?

Anonymous

I am using my old hard drive as an external drive with an enclosure.   I was able to delete the 2 partitions (1 had the OS) just fine.  But now there is a partition left that I cannot delete.  It says 63MB, Healthy (OEM Partition).  When I right click, I only get the Help option, and when I right click on the disk I only get the option to Convert To Dynamic Disk.  How can I delete the OEM Partition?

Thank you.

    Thanks ppclover and Microsoft for writing an excellent description of the diskpart utility.  I would also like to share how this worked for me.  I had a SSD with numerous partitions that I couldn't delete.  So I connected it to my desktop and did the following:

    1. In the Start Menu, type "run diskpart"
    2. type "list disk"

    IMPORTANT: Make a note of the disk number to be worked on, in my case #1

    1. type "select disk 1"
    2. type "list partition" - this step will show you all the partitions on the disk.  It will also help you make sure you are working on the correct disk.

    SUPER-IMPORTANT - Make absolutely sure you have the correct disk and not another HDD in your desktop selected in step 3

    1. type "clean all"

    This command writes zeroes to all parts of the disk and deletes all partitions

    1. type "list partition" and you will now see that there are no longer any partitions.

    Thanks for the reply.  Those websites got me on the right track for using the diskpart command line to do what I wanted, and it worked.  It took awhile because I have no experience using command line, and I wasn't sure if I had to include the [ ] brackets (no), and I had to figure out how exactly to write what I wanted  "delete partition noerr override", and I had to make sure that I selected exactly what I wanted to delete, but in the end, it all worked.

    I'm writing a long response in case someone else with a similar situation sees this and will know quicker how to get the job done.

    Thanks again.
