Ok, this may help people who already have win2k installed, want to install 98, and don't have a bootable win2k cd [like me].
I used a win98 boot disc to go through the windows98 installation process. Since that will wreck your boot.ini file, go to http://www.winimage.com and go to the 'bootpart' page. download and install bootpart, reboot to dos [as you should be in 98 at the moment], go to the bootpart dir, and type this....
bootpart winnt boot:c:
as it says there. this will restore win2k's OS loader and thus, you can choose to load 98 or win2k on startup.
