i have installed win 98 and 2000 server and dual booting working fine now i want add linux in this computer is it possible to install and how to make multiple booting

Yes, you can add Linux to the mix assuming that you have an empty partition for it. During the installation, it will give you a choice of booting up your system. Please pick either lilo or grub and add those two Windows OSes to the list also so you can boot them up... Always a good idea to create a bootable disk while you're at it in case you need to get into Linux again later... Lawrence

which o/s should i install first linux or windows

Windows 2000 needs to occupy the MBR so you could install 2K last. Most people seem to use a bootdisk to boot linux, so you can just install linux to another parition and use a bootdisk. That way you don't mess up your current MBR and NT Loader. T

I recommand you install Windows 98 first, then Windows 2000, and Linux last. That way, you can use either lilo or grub to boot up all three of them... If you install Linux before Windows 2000, Windows 2000 will wipe out your lilo or grub from MBR so you have to boot Linux using a floppy disk, then install lilo or grub again!!! Why not make it easy for yourself... Install Linux last. I have both Windows 2000 Server and RedHat Linux 8.0 running on a same system and I use lilo (on MBR) to boot up either one at the startup. No mess up of MBR here at all! Lawrence
