How do I add OS to xp boot loader?

I have three HHDs on one I have two copies of XP PRO and the other I have Xandros. The second copy of XP is beyond the boot boundary{ starts after the firsrt one which is 50gbs). I would like to be able to choose which one to boot from the boot screen. Is this possible with the XP boot loader?

 

Check your boot.ini file located in the root of C:\.

I dual boot XP & mine looks like this>

[boot loader]
timeout=3
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Hipster's Play Ground" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Rescue" /noexecute=optin /fastdetect

I don't know what effect Xandros would have on it.
