I have a multiboot system with solaris express developer edition 9/07 , fedora 7 and windows. all of them were working properly before I update my fedora system by "yum -y update".

My old /etc/grub.conf was :

#boot=/dev/sda
default=0
timeout=15
splashimage=(hd0,4)/grub/splash.xpm.gz
hiddenmenu
title Fedora 7 (2.6.21-1.3194.fc7)
root (hd0,4)
kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.21-1.3194.fc7.img
title Solaris XDE 9/07
rootnoverify (hd0,1)
chainloader +1
title Windows XP SP3
rootnoverify (hd0,0)
chainloader +1


and now (after updating fedora7):

#boot=/dev/sda
default=0
timeout=15
splashimage=(hd0,4)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.23.15-80.fc7)
root (hd0,4)
kernel /vmlinuz-2.6.23.15-80.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.23.15-80.fc7.img
title Fedora 7 (2.6.21-1.3194.fc7)
root (hd0,4)
kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.21-1.3194.fc7.img
title Solaris XDE 9/07
rootnoverify (hd0,1)
chainloader +1
title Windows XP SP3
rootnoverify (hd0,0)
chainloader +1


Now I can't boot solaris. after pressing enter a 'grub' is coming for a moment, but after a second again boot prompt is coming.

Please tell me how can I boot solaris.

thank you.

anyone please help.....

Can you clarify "after pressing enter a 'grub' is coming for a moment, but after a second again boot prompt is coming".

yum update is unlikely to have modified anything in the Solaris partition.

switch on my laptop..

boot fedora in 5 seconds...

press any key..

grub :

fedora (2.6.23...)
fedora 7 (2.6.21...)
solaris xde 9/07
windows xp sp3

i select solaris xde 9/07. press enter.

solaris xde 9/07
rootnoverify (hd0,1)
chainloader +1
grub

after a moment.....

boot fedora in 5 seconds...

You mean when you select SXDE, Solaris own Grub menu doesn't show up ?

yes... exactly !!!! please tell me how can I get solaris own grub menu again .

You probably need to reinstall grub on the Solaris partition.

Are you sure the Solaris filesystems/slices are still there ?

yes I am sure.

fdisk -l from fedora showing /dev/sda2 partition type as solaris.

and also , I checked it by sxde installation dvd. It's showing me that solaris is available in my harddisk , 'upgrade' option is also available which is probably disabled if a system doesn't have solaris installed.

please tell me how can I reinstall grub on solaris .

thank you very much.

should I execute this command by inserting installation dvd and choosing single user shell ????

above command solved my problem , I can use solaris again. but I have lost linux.

in my hard disk I have 4 partitions.
1. windows
2. solaris
3. linux
4. a ntfs partition

what should be written in /boot/grub/menu.lst ??
rootnoverify (hd0,2)
chainloader +1

or
rootnoverify (hd0,3)
chainloader +1

or
something else ???

In case of '2' , it's giving an error 'NTLDR is missing. press ctrl+alt+del to restart'.

ohh... I solved it...
i add the following lines in /grub/menu.lst and everything is now going on perfectly...

Glad you succeeded. Thanks for sharing your solution !

thanks boey your above command helped me to at least get grub menu back.
