I have Ubuntu , WinXP , openSUSE installed which having GRUB stage1 as (hd0,4) , and I just installed openSolaris and its having GRUB in (hd0,5).

So i went to change manually to get through solaris using grub editing , all showed successfull

When rebooted , I get the same GRUB window , and from there I edited once again to see through solaris [made my GRUB point to (hd0,5)], successful

But the problem is , when rebooted ,the GRUB console opens again , I couldnt figure out why its keep on coming , and I never get into my solaris

But when GRUB edited to (hd0,4) I can access rest of my OS .
IS this a GRUB fault , kindly help me to get solaris in my ubuntu GRUB menu list , I dont want to keep two GRUB pointers

did you add the entry for solaris in /boot/grub/menu.lst?

post your menu.lst here

IIRC, openSolaris needs primary partition and its bootloader should be installed in its root partition also it can only be booted by chainloading via grub.

btw, we need your menu.lst posted here.

There's the problem , now i'm not able to look solaris grub menu list , to copy that location to my Ubuntu's menu list .?

Is there anyway that i can see through from Ubuntu , will that mounting partition to folder works ?
Coz i havent done that operation yet

Can you run 'fdisk -l' without the quote marks from your terminal as root and post the results. You do not need to see anything in solaris except know the partition number it is located in to be able to chainload. Both posters above are telling you it needs to be in a primary partition and fdisk -l will tell them which partition.

Last I looked, the Linux grub was unable to handle OpenSolaris filesystems. Hence the OpenSolaris grub had to be the controlling boot-loader (i.e. in the MBR). Nowadays it can be used to boot Linux systems by adding them to the menu.lst
Should all be documented.

I have had no experience with solaris but in this article if I am reading right it was dual booted with linux by chainloading from grub.

http://www.kegel.com/linux/solaris.html

fdisk -l shows :

Partition table entries are not in disk order

That is a (very) old article. I can recall chainloading Solaris 10 as well. OpenSolaris defaults to zfs, and has some onerous (for open systems multi-boot users) requirements. See this and the next section.

See if this works:

1. have grub point to (hd0,4) - which is associated with openSUSE.
2. modify the menu.lst file in (hd0,4) to include:

title OpenSolaris
rootnoverify (hd0,5)
chainloader +1


3. reboot
4. now try to get into OpenSolaris

correction!
According to your fdisk -l, it seems you installed OpenSolaris to /dev/sda2. Assuming this is correct, do the following:

1. have grub point to (hd0,4) - which is associated with openSUSE.
2. modify the menu.lst file in (hd0,4) to include:

title OpenSolaris
rootnoverify (hd0,1)
chainloader +1

3. reboot
4. try to get into OpenSolaris

also, how did you know this to be true?

It seems that opensolaris partition is on primary partition and its an active one. To follow suggestion from btncix in post #11 you need to install opensolaris bootloader in its root partition. Have you done this...?

Grub cannot boot opensolaris directly...just as other posters said above...you need to chainload it.

If I read your article and understood, it refers to using solaris to boot other distros, not using grub to chainload. I take it as grub can not load directly. I will do more research today.

Sorry hurry hui, read your last post after I wrote mine.

Coz i'm having Ubuntu in (hd0,4) and after installing Solaris i come to know that its having one more GRUB , naturally its should be for Solaris , right? BUt i'm having unsuccessful installation of Gentoo , so thought of possibility only for Solaris GRUB as (hd0,5)

Any way i tried that menulist modification before as rootnotify (hd0,1)ur mention , it was just a trial , but it didnt work , same Error 15
