My physical C drive has win 98, My physical D drive has Win2000. I would like to replace the C drive with a new 160 GB drive, keep the D drive and let everything run from Win20000. I believe that the C drive has boot.ini. How would I approach this situation? Should I add the third drive, make sure it all works, then later remove the old C drive and let everything reassign itself, thus making the D drive into the C drive? Will that even work? Are there boot settings I should change first? Any advice greatly appreciated. Thanks
