Remove Windows 2000/XP/2003 but Keep Windows 98

I have a dual-boot configuration. How can I remove Windows 2000/XP/2003 from my system while keeping Windows 98?
To remove a Windows XP, Windows 2000 or Windows Server 2003 installation while retaining Windows 98 do the following:

1. Boot from the Win9x Startup Disk
2. Type: FDISK /MBR
3. Type: SYS C:
4. Reboot
5. Remove the Windows 2000/XP/2003 files & folders plus the following files:

Pagefile.sys
Boot.ini
Ntldr
Ntdetect.com
Ntbootdd.sys (might not exist)
If the W2K/XP/2003 OS was installed on a separate partition (see note below) you can now easily format that partition without loosing any Win9X configuration (as long as that hard drive partition is NOT the Primary Active partition!)
Note: When dual-booting always keep a separate partition for each OS. Never install 2 or more operating systems on the same partition because it will wreck havoc on you Program Files folder!
