Activating an local partition to the protection system in audit mode

HI

I have partitioned a disk into two primary partitions.

On one of them, I installed Windows 7 SP1 Ultimate 64 bit, but, during its installation, I pressed, the Ctrl+Shift+F3 sequence to go in audit mode.
Now, wanting to activate the D local partition to the protection system, I wrote:

or

but the D partition is still deactivated.

Why? So, how can I fix this?

THANKS

BYE
