How can I format my master hard disk in Vista?

Hi,
I have a two weeks custom built system.

Intel core duo 6600
RAM 2GB
Motherboard - ASUS P5W DH deluxe
Graphik Card - TwinTech 8600GT 256MB
Hard Disk master - Serial SATA 160MB
Hard Disk slave - Serial SATA 320MB - Formated
Hard Disk IDE 80MB - Formated

I googled for a while and I saw that some people had the same problem with windows XP (System Partition is not allowed to be formatted)
and they should delete the partitions, but in Vista it dos not let me delete the small 9MB partition.

Wenn I try to format my Hard Disk in the Command Prompt I see that message:

C:\Windows\system32>format C:
The type of the file system is NTFS.

WARNING, ALL DATA ON NON-REMOVABLE DISK
DRIVE C: WILL BE LOST!

Proceed with Format (Y/N)? y

Formatting 152617M

System Partition is not allowed to be formatted

C:\Windows\system32>

What if you have no option to format from Vist boot disc, I do the following steps
1. insert disc
2. click set up
3. Click install now
4.insert disc key
5. check "accept the license terms"
6. Open "Custom ( Adavanced)
then from ther all it says is there is already a version of windows installed, the old version of windows will be calle "windows.old" and you will not be able to use that version of windows.
teher is a note at the bottom of teh screen that says " To make changes to partitions, restart windows from the install disc,.. umm well I have many of time and still no change on install process, I have set the BIOS to even read the CDrom/DVD as primary???
