I have a dual-boot configuration. How can I remove Windows 9X from my system while keeping Windows 2000/XP/2003?
To remove a Windows 98 installation while retaining Windows XP, Windows 2000 or Windows Server 2003 do the following:
MSDOS.SYS
IO.SYS
If the Win9X OS was installed on a separate partition (see note below) you can now easily format that partition without loosing any W2K/XP/2003 configuration (as long as that 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!
