    About "Set Active/Inactive"

    When you install system on a hard drive, all the boot files will be saved together into the active partition, so boot partition and active partition is often the same partition. But, if you choose to set the original boot partition inactive and then set another partition active, you may be not able to enter system successfully the next time when your start your computer.

    As a result, under normal circumstances, we don't need to change the active partition (just keep the default settings). But, if we have added a new disk to computer and finished migrating OS from the original disk to the new one, we need to set boot partition on the new disk as active and then set it to be the first boot device in order to make computer boot from it successfully.

    Note: if you use "Migrate OS to SSD/HD" function of MiniTool Partition Wizard to transfer your OS to another drive, the software will set the new drive as active automatically at the end of OS migration.


    Now, the question comes – how to set active/inactive manually when necessary? We'll introduce the method of using "Set Active/Inactive" in MiniTool Partition Wizard.

    Here is the step-by-step MiniTool Partition Wizard tutorial you need.

    How to Set Active

    1. Select the partition you would like to set as active.

    Note:
    • If you're running a MBR disk, only the primary partitions on it can be set active. But if the disk is GPT, there's no such limit.
    • One disk can hold at most 1 active partition.
    • If you set the wrong partition as active and change the original active partition into inactive, you'll be blocked out from your system.
