The Solaris GRUB

Posted by Balachandran on January 14, 2007

Hello folks, Again I will be talking on GRUB terms…. The first thing I noted after installing opensolaris was that, it overwrites the GNU/Linux. I had an older version of Ubuntu running in the drive in which I installed opensolaris, and found to my surprise that the GRUB was overwritten by solaris.

Only then I learnt that the original GRUB from the GNU does not understand UFS or ZFS. The GNU GRB can understand only ext2 or ext3…. So the people from the Sun Microsystems have modified it and have released their own versions of it…

So, inorder to get linux back to working, we need to edit the /boot/grub/menu.lst file and give the correct path for the GNU/Linux root….. Or the other way of doing it when linux and solaris are in different drives is, install soalris grub in its drive and install GNU GRUB in the MBR… Then do as follows…

root (hd1,*)

chainloader +1

makeactive

savedefault

where * denotes the location of solaris root….. then it will work….
