hi,

Check the other OS file system exist in your hard disk by
login in into linux. use the following command

# fdisk -l

Check the grub.conf file under /boot/grub is correctly configured

give me output of fdisk -l and grub.conf file

Unhappy 3 OS's = confuse

when i do fdisk -l nothing comes out
here's the output :

[pitax@localhost pitax]$ fdisk -l
bash: fdisk: command not found


then i do this
[pitax@localhost pitax]$ su
Password:
[root@localhost pitax]# cd /
[root@localhost /]# cd boot
[root@localhost boot]# cd grub/
[root@localhost grub]# vi grub.conf


and result like this:

# grub.conf generated by anaconda
#
# 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 (hd0,2)
# kernel /vmlinuz-version ro root=/dev/hda6
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,2)/grub/splash.xpm.gz
title Red Hat Enterprise Linux WS (2.4.21-47.EL)
root (hd0,2)
kernel /vmlinuz-2.4.21-47.EL ro root=LABEL=/123 hdd=ide-scsi
initrd /initrd-2.4.21-47.EL.img

"grub.conf" 19L, 633C

Hi
run the fdisk -l command in root user

login as root then run the command

root# fdisk -l

see the result. you will find the filesystem of mac os.

then add the following lines at the end of the grub.conf



title MAC OS
rootnoverify (hd0,0)
chainloader +1


replace hd0,0 with the filesystem of the mac os.

if you find difficulty, post the output of the fdisk -l command
