You'll that was possible with the older 9x-ME Fat based versions rather then NT based there. Dual booting with 98/95 on the exact same partiion would see 98 installed last in the Window98 folder or other alteration since 95 would be in Windows. When 98 started you had the option to boot into 95.
With the newer NT cored versions you would edit the boot loader as well as copy boot files over from one primary to that of the newer version not see both installed on same there. The newer version's installer would replace the Documents as well as Program Files directories automatically as well as all user account info.
The smart move for seeing a working dual boot there would be seeing Vista installed to a second primary leaving the 5gb recovery partition intact unless planning to burn a set of recovery disks from that first! If left checked off the Vista installer will automatically reformat the intended partition selected.
