Making an Active Partition Inactive using Diskpart

If you are as stupid as me and manage to make a partition active that you shouldn’t have done, so long as you haven’t restarted the machine, there is a quick easy fix to put it right.

On the machine, do the following:

• Go into a Command Prompt
• Type “diskpart”
• Type “list volume”
• Type “select volume #” (# = the volume number that you wish to amend)
• Type “inactive”

This will then make the partition inactive and everything can return to normal!
