This method will only allow
you to make a Windows/DOS type of partition Active.
( You might be
using this method when you have tried to Shrink the volume for creating a
secondary drive partition. And the drive letter is not reflecting in explorer
as a new volume. And you assumed that it may be the reason that drive is not
yet active. And you accidently made the selection as below.)
CAUTION:
Using this method
will make your computer unbootable if you make an incorrect Primary partition
Active i.e. you will not be able to boot back to Windows to rectify the
alteration you made.
Note: The
warning you will receive from Disk Management is not entirely accurate. It
should read "... . If the selected partition does not contain the boot
files for an installed operating system, ...". It's the boot files that
load the operating system which itself may be installed on a different Primary
or Logical partition.
After completing this once
you restart the machine you get the below error.
