hi, friends i am working as programmer as well as hardware engineer... i am using separate bootable cd for each operating system. that means win98 for one , winxp for one cd,win 2000 p/s/as for one ,win 2003 for one now i want to combine all these in to one DVD . when i put that DVD System can boot with that and also ask for which OS You need(Means OS Choices)...
u can use MagicISO to built the iso file with the menu...what u need is the saperate iso file eg. win98, winxp, etc and make boot menu with magiciso or u can use GRLDR for making disc boot and even u can boot from usb flash using GRLDR for more info use uncle goole type Grub4Dos, and learn d tutorial
