You can do this several ways. First, open a terminal and type in

diskutil list

and hit enter. It should give you a list of your hard drives and partitions.
Each partition should show a partition type and a partition name (except possibly the Windows - it mat not have a name)

say your OS X 1 is on disk 1 partition 2 with name Snow Leopard 1 and a second OS X on disk 1 partition 3 with name snow Leopard 2. Win7 is on disk 2 with System Reserved on partition 1 and Windows NTFS on partition 2

edit your com.apple.boot.plist like so:
For default boot partition of SL 1, leave as is
For default boot partition of SL 2, add key to boot.plist

<key>Default Partition</key>
<string>hd(1,3)</string>

where 1 is your HD and 3 is partition of SL 2

You can also do it using name:

<key>Default Partition</key>
<string>Snow Leopard 2</string>

Hi,
I have the same question. I did change the plist file but chameleon still boots to OSX instead of booting to Windows. My com.apple.Boot.plist is now

<plist version="1.0">
<dict>
	<key>Kernel</key>
	<string>mach_kernel</string>
	<key>Kernel Flags</key>
	<string></string>
	<key>Default Partition</key>
	<string>Windows_NTFS System Reserved</string>
</dict>
</plist>

Any ideas ?
cheers

When you open terminal and do a diskutil list you get something like this:

/dev/disk2
   #:                       TYPE  NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                         *300.1 GB   disk2
   1:               Windows_NTFS  System Reserved         104.9 MB   disk2s1
   2:               Windows_NTFS  Win7                    300.0 GB   disk2s2

What you need is either

<key>Default Partition</key>
<string>hd(2,1)</string>

Where 2 is the disk number and 1 is the System Reserved partition like so:
Windows_NTFS System Reserved 104.9 MB disk2s1

OR

<key>Default Partition</key>
<string>System Reserved</string>

Where System Reserved is the Name of the partition
Windows NTFS you will note is under Type of partition

it's still not working for me. Here is the list of my disks:

me@desktop ~ $ diskutil list
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *640.1 GB   disk0
   1:               Windows_NTFS System Reserved         104.9 MB   disk0s1
   2:               Windows_NTFS                         315.0 GB   disk0s2
   3:               Windows_NTFS Data                    325.1 GB   disk0s3
/dev/disk1
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *500.1 GB   disk1
   1:                        EFI                         209.7 MB   disk1s1
   2:                  Apple_HFS Snow Leopard            499.8 GB   disk1s2

Here is the content of /Library/Preferences/SystemConfiguration/com.apple.Boot.plist:

<plist version="1.0">
<dict>
	<key>Kernel</key>
	<string>mach_kernel</string>
	<key>Kernel Flags</key>
	<string></string>
	<key>Default Partition</key>
	<string>hd(0,1)</string>
</dict>
</plist>

Here is the content of /Library/Preferences/SystemConfiguration/com.apple.Boot.plist:

Wrong com.apple.boot.plist. You need to edit the one in your /Extra folder.
