I had Win 2000 Pro before Installing Redhat Linux 8.0 which loads as default. But I want Windows to load as Default OS. How to do this? i guess its a grub loader. Details explanation needed.

Open /boot/grub/grub.conf in an editor. Look for line like default=N where N is the number of the default system to boot: N=0 means boot 1st operating system N=1 means boot 2nd operating system N=2 means boot 3rd operating system In the following example the 2nd operating system, "Red Hat 8.0", is the default operating system to boot: #boot=/dev/hda default=1 timeout=10 splashimage=(hd1,6)/grub/splash.xpm.gz title Windows XP Pro      rootnoverify (hd0,0)      chainloader +1 title Red Hat 8.0 (2.4.18-14)      root (hd0,6)      kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdc=ide-scsi      initrd /initrd-2.4.18-14.img title Red Hat 9.0 (2.4.20-8)      root (hd1,6)      kernel /vmlinuz-2.4.20-8 ro root=LABEL=/1 hdc=ide-scsi      initrd /initrd-2.4.20-8.img
