Guest Eric Posted August 21, 2007 Posted August 21, 2007 Does anyone know whay "Set partition to active" is about under Disk Management? I accidently select this option for [D: drive], hopefully, it does not cause any damage so far. I would like to know what this option is about and how to disable this option. Does anyone have any suggestions? Thanks in advance for any suggestions Eric

It will then execute the code stored in the Master Boot Record (MBR) of this active partition. If you mark the partition containing drive D: as active then the machine will probably not boot up.

The active bit, when set for a partition (only one can be set per physical hard drive at any given time and must be a primary partition), directs the system to look at that hard drive for boot files in a specific location specified by that partition. If those files do not exist or the pointer for boot files does not exist, the PC cannot continue. As with all versions of windows, the actual boot files are located on the C: partition. Not to be confused with the XP definition of windows boot partition. XP calls the boot partition where the boot files and boot partition are located, the system partition. If you're confused, so was I when I first saw this. I'm still confused about the descriptor "boot" and "system". Seems intentional to me. Dave
Guest Eric Posted August 22, 2007 Posted August 22, 2007 Re: What is "Set partition to active" under Disk Management? Thank everyone for suggestions Does anyone know how to disable the active partition for [D: drive] without formating it? At this moment, I still can turn on / off my computer with no problem. It seems Disk Management doesn't offer any option to disable this active one.

Guest Andy Posted August 22, 2007 Posted August 22, 2007 Re: What is "Set partition to active" under Disk Management? An active primary partition only matters if you're trying to boot from the disk that contains that partition. In other words, if you set the BIOS to boot from the second disk drive, then the boot files for the operating system has to be in that active primary partition. Since the BIOS is set to boot from the first disk drive, the active primary partition on the second disk drive is of no consequence.
