removing server 2000 from a XP/Server 2000 dual boot system

i have been trying to find a way to remove the hole of server 2000 for my pc without loosing XP pro SP2 or even just the boot log.. the problem i keep running into is everyone is telling me that its on a partition or a secondary hard drive… but.. its not…

there are no partitions to this hard drive at all… im not the one that put it onto the pc.. so i dont even know how it worked at all..
