Win2k and ME dual boot snafu…

I had a functioning win2k os running. I booted from an ME CD and installed ME to a different directory. I thought I would get the boot menu offering me 2 different OS options. Now it boots straight into WinME and after looking for a boot.ini file(NT), I realize there isn’t one in 2k or ME. How do I fix this, so i can dual boot or switch back to win2k. HELP! Thanks..
