Access Solrais OS from Linux GRUB

I have installed 3 OSs on my laptop (Win2003, FC7, Solaris Express CE),I used to use Linux grub to boot these 3 OSs without any problem.

Linux OS screwed up for some reasons, I reinstalled linux OS without touching windows nor solrais, as a result I have to edit the Linux grub by adding the same 3 lines that were there before reinstalling linux,:

Code:

title Sun Solaris GRUB Boot Loader
    rootnoverify (hd0,3),,,,,solaris on sda4
    chainloader +1

http://www.sun.drydog.com/faq/9.html

I tried below as well

Code:

title Sun Solaris GRUB Boot Loader
    rootnoverify (hd0,3),,,,,solaris on sda4
    makeactive
    chainloader +1

Although I have added the lines above (which are same to the lines before reinstalling linux) , still Linux's grub can not boot solaris OS!!!!!

At this stage, I do not like to use Solaris's grub to boot linux OS.

If you are going to install the Solaris 10 1/06 OS, navigate to /boot/grub/menu.lst. Make a note of the paths to the Linux partition, Linux kernel, and Linux RAM disk. You will need this information later.
The menu list should be something like this:
root (hd0,1)
kernel /boot/vmlinuz-2.6.9-1.667 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.9-1.667.img

Linux grub cannot boot Solaris but it should be able to chainload to Solaris Grub.

What is the error message, if any, you got ?

No error, I will be forwarded to Linux's grub again.

Can you post your partition table ? ("fdisk -l" output)

Your primary partitions 3 and 4 seem to have been reordered. That may explain the problem.

aus9 · 01-02-2008, 07:27 PM

I suggest make your system more simple

part 1 primary ntfs
part 2 primary solaris
part 3 linux
part 4 linux swap

if fat32 was for sharing of ms and linux..make part 1 available to be readable and or writeable in your linux fstab....writeable is now possible with ntfs-3g

Beware that if partition 4 is a primary partition, you need to manually change its id to something else than 0x82 otherwise Solaris will probably be in trouble.

There is no ntfs write support with Solaris so the fat32 partition is still relevant if sharing is expected from the three installed O/Ses. I personally prefer to use an USB memory device for that use instead of wasting a primary partition.

Sorry for the previous reply that I have posted,showing that line for sda4 before sda3,,,,,I do not how that happened ,,,,,please see the correct one below :

[root@localhost ~]# fdisk -l

Code:

The number of cylinders for this disk is set to 14593.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

according to the above thread the origin partition table was like this

Code:

[root@localhost ~]# fdisk -l

/dev/sda8           14466       14592     1020096   82  Linux swap / Solaris

When I reinstalled solaris (deleted its partition and recreated it again) the partition table changed to the below : (I guess this is normal)

Code:

Disk /dev/sda: 120.0 GB, 120034123776 bytes

Every thing was working fine (I would have been able to boot all threre OSs by using Linux grub) , till I reinstalled Linux recently because there was a problem with its Xorg11.

Now I can boot Windows and Linux by using Linux grub, but not Solaris

Under Linux fdisk .dev/sda and select the expert options (x) and then select fix partition order f), the order of the partition tables in like below.

I have never installed solaris but I know you can chainload to solaris or alternatively use grub hide commands to hide partitions after partition 2?

jlliagre · 01-03-2008, 12:38 AM

After fixing the partition order, did you try

Code:

rootnoverify (hd0,2)

?
