Boot more than one Linux Systems

NoviceW · 11-11-2003, 04:29 PM

I have installed WinXP, SuSe, Mandrake and Fedora on my computer in different partitions. After I installed Fedora as my last operating system I choosed as the GRUB boot loader as the default. On startup now it shows me only Dos and Fedora. Please let me know in detail, how I could make GRUB to boot other two operating systems as well.

My partition table shows following information.

Mandrake
hda 6 ext3
hda 7 linux-swap
hda 8 ext3

Suse
hdb 6 linux-swap
hdb 7 reiserfs
hdb 8 ext3

Redhat
hdb 9 ext3
hdb 10 linux-swap

This would help bunch of other guys planning to do the same.

Thank you in advance

Edit the /boot/grub/grub.conf file to reflect your stuff

Code:

# Celeron 850 tinwhistle /boot/grub/grub.conf file
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,1)
#          kernel /vmlinuz-version ro root=/dev/hda6
#          initrd /initrd-version.img
#boot=/dev/hda

        initrd /initrd-2.4.20-18.7.img

My partitioning scheme:
