grub problem 1

[supership]

hi , was using solaris in dual boot with xp , then I ' ve installed ubuntu too . The solaris grub has been in some way damaged , maybe because during the linux installation i've delete an old partition that I was not using by some months. It's normal that the solaris grub has been overriden by the linux one , the problem is that when I start the solaris partition throught the linux grub , I obtain the Minimal bash-like line of the grub , just like this:

grub >

to start the solaris partition from here I've to execute these commands:

root (hd0,1,a)
kernel /platform/i86pc/multiboot
module /platform/i86pc/boot_archive
boot

anyone knows what file or configuration should I modify to make solaris start without doing all this work?

In a Solaris grub menu those options (except for boot) would show up in /boot/grub/menu.lst... I would assume that the grub menu.lst being used now should have seperate sections (with the appropriate entries) for XP, ubuntu and solaris...

I've never worked with grub before , so I really have no practice with, maybe it can help if I post my grub file . This the linux grub file

as I said when I boot the solaris entry in the linux grub it appears a sort of grub prompt with the " grub >" command line. From what I could understand , when I enter the solaris entry from the grub , the solaris partition it loaded, but the solaris grub installed in it is damaged?may it be? if so , is there a way to reinstall the grub on the solaris partition , WITHOUT override the linux one? I saw the setup command in the listed ones , but not sure of what it really does. I hope I've not been confusing in the explanation.

You see how the Solaris entry in the linux grub menu is missing the kernel, module and boot commands? Those are the items that should be added (similar to how it is in the solaris grub file)...
