DUAL-BOOT XP/2000/NT & WIN9x
[Win XP or Win 2000 or NT] already installed
http://tweakhomepc.virtualave.net/dualboot/dualxp9x.htmlHow to Add a Win9x/Me to an existing Win XP, or 2000, system.
You have two options:
1. Install the Win9x/Me as the first OS, and then Reinstall Win XP or 2000.
This option is very safe, but takes time and data loss occurs.
2. Install the Win9x/Me, and then Repair the Win XP/2000/NT boot sector.
This could be less reliable, but it's shorter and no data lost occurs.
Critically, don't forget that Win9x/Me can only use FAT or FAT32.
A different operating system should be installed on its own logical drive.
