you have to boot from something else, whether it be a floopy disk, thumb drive, or setup cd. you can't delete files that you are currently using. if you boot into windows xp you can't delete windows xp.

Nothing was techinically "replaced", but they booted in phases rather than specific files. This lead to adding bootmgr(Windows Boot Manager) which reads a registry type file that was not used in Windows XP.
The boot files are in C://Windows/system32
You'll need to set up at least two boot partitions on the "C:" drive, one for XP and one for 98. Then you'll have to get a boot loader that lets you select which OS you want to boot.
