Hi All
I have a problem.
My system specs are P III Celeron 900MHz,256 MB RAM, 80 GB HDD on
Primary master, 40 GB on Primary slave, DVD ROM-Secondary slave,
DVD-Writer Secondary master.
In 80 GB Primary master, Win XP and Debian 4.0 are installed in
separate partitions (hda1,5,6,7 for windows, hda8 for debian).
In 40 GB Primary slave windows accessible partitions were there
and in hdb7, earlier mandrake was there and Ubuntu 7.04 was installed
later and the GRUB of Ubuntu (installed in MBR of first HDD)took care
of all the 3 OS's and I was happily booting into all the 3 OS's at
will.
Then I installed/upgraded Ubuntu 7.10 and then 8.04 also in the second
Hard disk. But the GRUB displyed GRUB error 18 and I was unable to boot
into Ubuntu.
I googled and all were suggesting a small /boot partiton in a place
accessible to GRUB and all. I thought all that problem went out the
window with LILO! And all the while while using Ubuntu 7.04, no
complaint of GRUB error 18 was seen! This came to the fore only on
upgradation of Ubuntu! Is it because GRUB is in such a bad condition
that once it is installed in MBR of first HDD that it is not able to
boot OS in second HDD? If so what magic was there earlier that it
booted older ubuntu?
Can anybody help? Pointers please?

Hi,
Check whether this set of commands helps you in any way.
1. Boot the Desktop/Live CD.
2. Open a terminal (Applications -> Accessories -> Terminal)
3. As root run the following commands:
sudo grub
grub> find /boot/grub/stage1 # Note down the output. It will be like
(hd0,0)
grub> root (hd1,0) #Hit the <Enter> key
grub> setup (hd1) #Hit <Enter> key
grub> quit #Hit <Enter> key, quits grub
5. Reboot (to hard drive).Grub should be installed properly and you should
be able to continue with your ubuntu
Cheers!
Siraj.
