Windows Forum / Windows XP / Setup and Deployment / February 2007Cannot Mark Partition as Active Using Disk Management
I have divided my harddisk into four partitions: 3 primary and 1 logical drives. I am unable to mark any of the primary partition as active using Disk Management found in Computer Management as the option is greyed out. I also have Norton Partition Magic 8.0 installed in my PC. Can somebody advise why? There can only be 1 active partition per hard disk. You already have an active partition (the System Partition) and Disk Management will not allow you to remove the active flag from the System Partition, it it did then your computer would not boot the next time you restarted it... or at least it wouldn't boot to the expected Windows installation. Why are you trying to change the active status of the partitions? John > I have divided my harddisk into four partitions: 3 primary and 1 logical > drives.

I have no problem switching for the 2 Windows XP partitions using Partition Magic 8.0 but not Windows Vista as it does not support the software. Hence I want to use the built-in disk manager in Windows. > There can only be 1 active partition per hard disk.

Give this a try, it makes it easier to work with the boot loader: http://www.vistabootpro.org/ BootIt NG can boot all Windows versions: http://www.terabyteunlimited.com/bootitng.html In my other post I stated that the Disk Manager would not allow changing the active partition flag, that is incorrect. The Disk Manager allows toggling of the active partition, I'm not sure why you can't do it, maybe Partition Magic has something to do with it.

You can have many "active partitions on the hd" ,youre problem on not being able to set as "active",they are in a raw state,format them,then set as active. > I have divided my harddisk into four partitions: 3 primary and 1 logical > drives.

You can toggle the active flag from one partition to another but you cannot have more than one active partition on an MBR disk.
