How to Set Partition as Active?

Do you have multiple partitions on your computer with different operating systems installed? If so, you can change the active partition in Windows so that when the computer boots up, it will load the appropriate operating system.

Please Note:

  1. A logical drive or extended partition cannot be set as active, only primary partitions can be changed to active.

  2. You can only have one active partition on a physical hard disk.

  3. If you have several physical hard disks on your computer, you can set a partition as active on each disk, but only the active partition on the first hard disk detected by your BIOS will start up the computer. You can go into the BIOS and change the order to detect hard disks.

To set a partition as active, please do as the following steps:

Step1: Launch Partition Assistant Server.

Step3: There will be a pop-up window which gives you an attention. Then click "OK".
