Ubuntu Grub Problem

[Ecko]

Title says it all guyz but let me explain u a bit more
Tried Installing Ubuntu on Ext 3 partition on my SATA HDD*
The installation turns well but I neve see GRUB @ boot so I'm unable to boot into Ubuntu
Also i've tried the same thing in VirtualBox with single PATA HDD which works pretty fine
Since I dont know what to do please help
I've 2 HDD (320 SATA & 80 PATA) connected with partitions going to 12 (including the SWAP)
I've installed the Ubuntu in 11th partition (Ext3) of HDD(0) i.e SATA*

You have to install Grub on the MBR of your 1st Hard Drive. Use GParted Live CD and open a Terminal and enter

sudo grub

find /boot/grub/stage1

It will give you somethig like (hd0,6).
Enter

root (hd0,6)

setup (hd0)

Change (hd0,6) with the results of find /boot/grub/stage1.
I hope i understood your problem correctly.

[Ecko]

find /boot/grub/stage1 command gives me result as hd(1,10) which I think should be hd(0,10) rather than it
But I'm still unable to complete it as I dont have Gpart CD but I only have Ubuntu CD
If that can do the needful or is there any other way around

[Rahim]

Yah ubuntu cd will do. The numbering depends on which drive is recognised first in BIOS.

[Ecko]

Yaar its not performing the rest of commands u've mentioned
I'm able to perform just 1st command

[Rahim]

Have you entered it correctly? root (hd1,10) and setup (hd0)
You kkindamessed with the brackets. What errors are you getting?

[Ecko]

K let u know in few minutes

[NucleusKore]

My suggestion
Boot with GParted live cd and confirm on which drive is your linux ext3 Ubuntu partition

Then refer this tutorial
http://thinkdigit.com/forum/showthread.php?t=96132

and in that:
*Boot with Ubuntu and install grub to your root partition as outlined in the above tutorial.
*Then install the GAG boot loader as outlined in the above tutorial

You should be fine

[Ecko]

Guyz Unable to load grub even after trying the method by rahim
Will try the Gparted CD
Also not to remind that I'm able to do so exactly same in VirtualBox

[Rahim]

Ecko try the above method but this time enter setup (hd1) instead of (setup (hd0)

There should be space between root and ( and bracket and (

[Rahim]

^The space is there,isnt it?

[NucleusKore]

I think he might as well put the boot loader in his root and install GAG. It's a lot easier.

[Ecko]

Ok another problem here guyz

ya i'm intelligent enough to type commands

Tried this

Ecko try the above method but this time enter setup (hd1) instead of (setup (hd0)

It worked fyn rather excellent but Im now unable to boot into XP
Plz guyz help me out

This is what you called digging your own grave and burying yourself in it. Manual editing is not for the faint hearted.

Download SUPERGRUB from here
http://www.supergrubdisk.org/
and burn it to a cd

Boot with it and select the automatic option to restore your windows boot record ((((((((((((

Then boot with the Ubuntu cd (live mode), open a shell and install grub to the Root partition as outlined in my tutorial.

Install GAG as outlined in my tutorial

[Ecko]

Yaar its in Root partition
I've done exactly the same as said in ur tut

[NucleusKore]

Boot with GParted and a pendrive in place
Take snapshots of both your hard disks and save them to the pendrive
post them here, let us see

[Ecko]

i'll post them from ubuntu 's Gparted
Ext3 is sda11




The (sdb1) is Windows XP

Ok here is an update
I edited the grub lst file to change from hd(1,10) to hd(0,10) because this was the only setting for which Ubuntu was booting

Still windows xp isn't booting so using SuperGrub CD to boot in XP
How abt changing the grub to same setting as Supergrub ??

[damked]

I have not used Ubuntu but there may be a way to this if right utilities are there.
Boot into your Ubuntu and in system utilities search for some utility which will let you to change boot loader settings in graphic interface. From there you will be able to add a menu which will let you to boot into windows. I

[Rahim]

Edit /boot/grub/menu.lst and make an entry for XP:

# on /dev/sdb1
title Microsoft Windows XP Professional
root (hd1,0)
savedefault
chainloader +1

See if this helps Not sure though as i dont know much about SATA.

[NucleusKore]

Ok now one step at a time. Use the supergrub boot disk to restore your boot record to windows xp only. This means that you will be able to boot into xp without the help of supergrub. Ten come back here I will tell you what to do next.

[Ecko]

Done Guyz*
Next Step Plz

Edited the MBR so that now I can just use Windows
No Ubuntu 4 now

[NucleusKore]

Is you root partition the roughly 16 GB sdb11?

Boot using the Ubuntu live cd and select the first option to run ubuntu from it without installing.
After the desktop loads press Alt and F2

Type
gnome-terminal
and press ENTER

Install GRUB to your root partition. In a terminal type

grub-install /dev/sdb11

and press ENTER.
Close terminal

Now install GAG as outlined in http://thinkdigit.com/forum/showthread.php?p=925088#23

[Ecko]

Is you root partition the roughly 16 GB sdb11?

Ya

Doing now
Will post in 5 minutes

Unable to create directory using abover command
It says ubale to create GRUB Directory (probably due to root nature of installation in that folder)
What to dow now ??

[NucleusKore]

Type the commands as above in a terminal and post the screenshot. I'll see tomorrow, Goodnight

[Ecko]

I'm unable to create directory dats it
Nothing else
I'm booting using Ubuntu CD so atleast what I guess it that due to security reasons it woesn't allow any creation of folder in root drive
Atleast I know how to use terminal & few other things
I'm not a new noob but Im a Old Noob

Will post the screen shot too

[NucleusKore]

I just realised something

What's this!!



Those warning signs and key like things??

---------------------------------------------------------------------------------------------------------------------------------------------------------------

Silly me
I got it

When you boot with a live cd the partitions are NOT automatically mounted. No wonder you cannot make a directory

In gnome terminal

sudo mkdir /mnt/share

and press ENTER

Then type

sudo mount -t ext3 /dev/sdb11 /mnt/share

and press ENTER

Then type

sudo grub-install /dev/sdb11

and press ENTER.
Close terminal

Now install GAG as outlined in http://thinkdigit.com/forum/showthread.php?p=925088#23

[Ecko]

It says

Could not find device for /boot: Not found or not a block device.

Any problem with that ??

[NucleusKore]

Looks like i am all mixed up
see this post
http://ubuntuforums.org/showthread.php?t=224351

So modify the above as follows

In gnome terminal

sudo mkdir /mnt/share

and press ENTER

Then type

sudo mount -t ext3 /dev/sdb11 /mnt/share

and press ENTER

Then type

chroot /mnt/share /bin/bash

and press ENTER

Then type

sudo grub-install /dev/sdb11

and press ENTER.
Close terminal

[Ecko]

Got error while executing chroot command(unable to change directory....) so went to link u mentioned
Followed every command mentioned there( I think you didn't wrote 1 or 2 of them)

Followed all instructions with sdb11 in place of everything else & it worked fyn

But still GRUB isn't @ boot
Will it be shown @ boot only after I install GAG ??
