Default GRUB failure

Thank you in anticipation.

Assuming your boot drive is hd0
(i.e. /dev/sda),

and your Linux root partition is /dev/sda2

and filesystem is ext3:



boot a any modern Linux live CD.

su -

mkdir /mnt/sda2

mount -t ext3 /dev/sda2 /mnt/sda2

chroot /mnt/sda2

cp /boot/grub/grub.conf* /tmp

grub-install --recheck /dev/sda



exit

reboot



eject the CD while PC is running power-on self test.



You should gate the basic grub menu.

once you boot up, edit /boot/grub/grub.conf

and compare it to /tmp/grub.conf.

You should be able to restore missing entries

in /boot/grub/grub.conf* from /tmp/grub.conf.



Good luck.

It may be a case of a bad mbr. Have you tried to rebuild it?

Bret, grub-legacy is getting kind of 'rusty' now for me. But I'll try to
bring up whatever I could. If someone out here can add or help, that
will be good.


At grub prompt, we will need to set back the 8.04 grub-legacy grub to
mbr. To do that the commands are (at the grub prompt)


root (hdX,Y)
setup (hd0)
quit

or use chainload (at the grub prompt) to boot up ubuntu

root (hdX,Y)
chainloader +1


If you don't know, and it's always best to be sure, what the (hdX,Y)
is,(at the grub prompt), issue this command..

find /boot/grub/stage1
You will be given 2 input as you have Debian 5 there, (use the ubuntu as
we here are more familiar with it).


Once you booted up to ubuntu, at terminal
sudo grub-install /dev/sda (assuming sda)

But you may have to be prepared for more serious problems unrelated to
grub itself, but hopefully, try this out first before we go there.


Good luck - Goh Lip

Default GRUB failure

Bret Busby Ask:

Hello.

I have a "laptop" computer with winXP Pro, Unbuntu 8.04 and Debian 5 (I think it is 5), installed.

With a recent electricity supply failure, I ran an orderly shutdown on
the computer.

Since that shutown, each time that I reboot the computer, it takes me to
the GRUB prompt (rather than the GRUB boot menu), and
I cannot boot the computer into any operating system.

How do I get GRUB to configure itself, to detect the installed operating systems so the computer is usable once again?

Or, has GRUB destroyed the software build of the computer, and all of the data, requiring a complete reinstallation of all of
the operating systems installed on the computer?

-----

Bret;

Most likely your system is fine, just Grub is having issues finding you OS's. I have had this issue a couple times recently on my Testing install after upgrades, I figure in my case it's due to having 5 h.d.d's

But more to the point. You boot and get

grub>

Prompt, right?

I am tired so you may have to do a little research to get your commands straight, but if you boot a live distro, say a current KNOPPIX disk, it should load with GUI and all.

In shell:

$su

#blkid (or equivalent to identify your BOOT os's hdd and partition)

Mount that drive somewhere, example: /mnt/root

#chroot /mnt/root

#grub-install (man or --help for triggers, I forget them all, will have to at lest define drive and partition to install to, example: (hd0,1)

If grub install errors out and says something about not finding /dev or somesuch you can exit out of the chroot and

#exit
#mount --bind /dev /mnt/root/dev

Then

#chroot /mnt/root
#grub-install

I have gotten the /dev error a couple times before, could have to bind /proc, /sys, or others. But in my experience only do so if grub-install complains about not being able to find that specific directory.

I know this reply is kinda spliced but I'm in middle of working 24+ hours in a day and half. I waited to see if anybody else would form a clean answer, but nothing yet. so I tried.

----

I will also add, I am not sure which partition you had grub booting from. Ubuntu or Debian...

But the version of grub that was installed is important. Debian Testing or "Wheezy" is using Grub2, I forget if Debian Stable or "Squeeze" was updated to use Grub2 before release, or what version of Grub will be on the Ubuntu system if it was your Boot Partition..

What ever the case, use a Live CD with the corresponding version of Grub otherwise it won't work...

Current Knoppix uses Grub2. If your systems were up to date it is good odds they were using grub2 as well...

If you mount the boot partition there will be a modules directory for grub, I forget the path though, something like /etc/grub/modules.d/ a grub1 install will have a /boot/grub/menu.lst file for sure... Grub2 removed that and went to the module directory set up.

I don't think grub would do that. Hard drives do fail, and laptop drives are
prone to failing more often than desktop.

There's a good chance all your data is there, but this is an excellent time
to back up your files from all of your OSes.

You can boot the Ubuntu CD and run it 'live' - meaning from the CD. It will
allow you to get to your files.

Also, once you are running from the CD, open the gnome Disk Utility. In the
program, select your laptop drive and click the Smart Data button. See if
all the bullets are green, or see if there are any red ones. It will tell
you if the drive is healthy (trustworthy) or not.

If you can't find your drive in the Disk Utility list, it's possible its
dead.

Just one more thing....(forgot this)

So how did it turn out, Bret?

Bret Busby Ask:

Hello.

I have a "laptop" computer with winXP Pro, Unbuntu 8.04 and Debian 5 (I think it is 5), installed.

With a recent electricity supply failure, I ran an orderly shutdown on
the computer.

Since that shutown, each time that I reboot the computer, it takes me to
the GRUB prompt (rather than the GRUB boot menu), and
I cannot boot the computer into any operating system.

How do I get GRUB to configure itself, to detect the installed operating systems so the computer is usable once again?

Or, has GRUB destroyed the software build of the computer, and all of the data, requiring a complete reinstallation of all of
the operating systems installed on the computer?

-----

Bret;

Most likely your system is fine, just Grub is having issues finding you OS's. I have had this issue a couple times recently on my Testing install after upgrades, I figure in my case it's due to having 5 h.d.d's

But more to the point. You boot and get

grub>

Prompt, right?



Yes.

And now I wish for the return of lilo.

I had not wanted to change from lilo to GRUB, when the change came. From
memory, it was a forced change ("If you want to be able to have multiple
boot choices, you now have to abandon the reliable lilo, and use GRUB
from now" - "Abandon hope, all who enter").


It think that lilo was fairly stable. I do not remember having had
problems with it.


I had assumed with getting the GRUB command prompt, it would have had
some command that could be entered at the GRUB command prompt, and that
would detect the installed operating systems, and create a new boot
menu, as (I believe) GRUB does when it is installed. I could not find
any such command, in my online searches


With the response so far, it seems much more complicated, and so will
have to wait until I have a few hours to spend with it.


My experience with such system tasks, is that what appears to be
something that should take about 5 minutes, usually ends up taking hours
or days.
