modifying bootcfg

I posted before with a problem about dual booting and how Server 2003 overrode my Vista x64 boot partition. I can see the files on my machine, and when I try to open the Vista bootcfg file, Server 2003 tells me it is a valid boot file, but that it won't work on my "machine."

Does anyone know how I can effectively delete the Server 2003 partition or re-enable my Vista x64 bootcfg to the primary position without destroying my system and all my data files?

Go into disk Management, and mark Vista Partition as "active", then delete server 2003 partition, then extend the Vista partition (if you choose).
start> right click "computer", select "manage">click "continue">click "storage-disk management">right click Vista partition and select "mark partition as active"

Go to msconfig and select boot and delete the 2003 entry.
start>in search, type msconfig>hot "enter">click "continue"> select "boot" tab

ReBoot into Vista advanced recovery utility (see below):
