did i just lose my other OS???

[unix1adm]

I have gparted on my system and i have opensolaris running in one partition. I loaded Suse on another partition but now I don get my grub menu so i can select my boot image.

How can i get back to my opensolaris to put suse in the grub menu?

I also plan on loading redhat on this system.

HELP...

[unix1adm]

i booted from y gparted cd and the partitions are still there. Now the question is how to get back to a boot option on them...

[unix1adm]

So I booted into safe mode and i notice grub is used here too. I am guessing i have to change the menu.lst file. But what if I want to use my opensolaris grub menu? How do I not make suse the default boot/grub loader?

I tired this in the menu.lst but it gave an error

title Boot OpenSolaris
rootnotify (hd0)
chainloader +1

This is what my solaris menu.lst had in it. However it wont boot.

[unix1adm]

I removed the suse partition and now i get

GRUB Loading stage1.5.
GRUB loading , please wait
Error 22

[unix1adm]

i gave up after trying several things and reloaded the original OS. will try this later

What does your grub.conf say? You set the default OS to boot with the "default" parameter. A value of "0" will select the first, "1" will set the second, "2" will set the third and so on. Here is known working example I found on the Web.

 
default=0
timeout=10
splashimage=(hd1,2)/boot/grub/splash.xpm.gz
title Fedora Core (2.4.22-1.2174.nptl)
    root (hd1,2)
    kernel /boot/vmlinuz-2.4.22-1.2174.nptl ro root=LABEL=/ hdd=ide-scsi
    initrd /boot/initrd-2.4.22-1.2174.nptl.img
title Fedora Core (2.4.22-1.2149.nptl)
    root (hd1,2)
    kernel /boot/vmlinuz-2.4.22-1.2149.nptl ro root=LABEL=/ hdd=ide-scsi
    initrd /boot/initrd-2.4.22-1.2149.nptl.img
title Fedora Core (2.4.22-1.2129.nptl)
    root (hd1,2)
    kernel /boot/vmlinuz-2.4.22-1.2129.nptl ro root=LABEL=/ hdd=ide-scsi
    initrd /boot/initrd-2.4.22-1.2129.nptl.img
title Fedora Core (2.4.22-1.2115.nptl)
    root (hd1,2)
    kernel /boot/vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdd=ide-scsi
    initrd /boot/initrd-2.4.22-1.2115.nptl.img
title Windows XP
    rootnoverify (hd0,2)
    chainloader +1
title BEOS
    rootnoverify (hd0,0)
    chainloader +1

Your config below may have an error according to this link. It should look like this:

title Solaris
        rootnoverify (hd0,2)
        makeactive
        chainloader +1

Have you tried running grub-install or grub afterwards? Are you sure you are specifying the correct partitions in grub.conf?
