Dual Boot

I have one hard drive with 98 second edition and a second hard drive with 2000 installed in the same PC. What is the procedure for moving the 2000 hard drive to a new PC and still be able to boot either the 98 or 2000 system? There is a boot.ini onboth drives. Can I just copy the boot.ini from the 98 drive to a new 98 drive on the new PC and be able to boot from either the 98 or 2000 system?
