Replacing disk now grub 15 error

[SimonT]

I have a dual boot system windows xp and Ubuntu, My disk had a few bad block and was also quite small.

I cloned my disk on to a bigger larger disk but when I changed out the disk my grub loader came up with error 15

This is what my disks look like when both are connected
(in windows)

This is my current menu.lst

http://pastebin.com/m140be1e5

Any ideas why it can not see partitions when booting with the larger harddisk ?

I think it might have been the clone software that I used does any one recommend some thing that will also clone the MBR area ?

[mikewhatever]

Check the uuid of the new root partition with sudo blkid, it's probably a different one to that you have in the menu.lst (see below).
#
kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=0b77b069-d566-4e2e-989a-b68dab3636ee ro quiet splash

[SimonT]

Thanks for the hint I will install the new drive boot up a live cd and see if I can get the UUID, As I dont think you can get this from windows.

[SimonT]

Current drive

ubuntu@ubuntu:~$ sudo blkid
/dev/loop0: TYPE="squashfs"
/dev/sda1: UUID="BC78488E784848FA" TYPE="ntfs"
/dev/sda2: TYPE="swap" UUID="faa0dea0-9647-4872-b189-df01a91ddbcc"
/dev/sda3: UUID="0b77b069-d566-4e2e-989a-b68dab3636ee" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda4: UUID="064d9848-ad9a-48fa-bd9c-ebe71d14b1d3" SEC_TYPE="ext2" TYPE="ext3"

with new drive attached by USB

ubuntu@ubuntu:~$ sudo blkid
/dev/loop0: TYPE="squashfs"
/dev/sda1: UUID="BC78488E784848FA" TYPE="ntfs"
/dev/sda2: TYPE="swap" UUID="faa0dea0-9647-4872-b189-df01a91ddbcc"

/dev/sdb1: UUID="faa0dea0-9647-4872-b189-df01a91ddbcc" TYPE="swap"
/dev/sdb2: UUID="0b77b069-d566-4e2e-989a-b68dab3636ee" TYPE="ext3"
/dev/sdb3: UUID="064d9848-ad9a-48fa-bd9c-ebe71d14b1d3" TYPE="ext3"
/dev/sdb4: UUID="BC78488E784848FA" TYPE="ntfs"

So what drive should I change in my menu.lst and replace as the new UUID ?

[rreese6]

I believe it is possible to replace the UUID with the device
such as /dev/sda3 . once grub is up just hit e to edit and replace the UUID with the device.
try to substitute this for the entire UUID=xxxxxxxxxxxxxxxxxxxxxxxxxx part. "root=/dev/sda3" (without quotes).

in /boot/grub/menu.lst

kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=0b77b069-d566-4e2e-989a-b68dab3636ee ro quiet splash

kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=0b77b069-d566-4e2e-989a-b68dab3636ee ro single

change to:

kernel /boot/vmlinuz-2.6.20-15-generic root=/dev/sda3 ro quiet splash

kernel /boot/vmlinuz-2.6.20-15-generic root=/dev/sda3 ro single

Let me know how this works out for you. the drive is known by taking the hd nuber and coverting. (hd0,2) is first drive(sda),partition(3).
counting starts at 0 not 1, so 0=1 1=2 2=3 etc.

once it is up do the blkid again to get the real numbers and reverse operation.
I have done this on various hd's sucessfully.

[SimonT]

One thing I could do is as the system is cloned on to the new drive is look what partition currenty has the

UUID=0b77b069-d566-4e2e-989a-b68dab3636ee

and then see what it is on the clone drive


/dev/sdb1: UUID="faa0dea0-9647-4872-b189-df01a91ddbcc" TYPE="swap"
/dev/sdb2: UUID="0b77b069-d566-4e2e-989a-b68dab3636ee" TYPE="ext3"
/dev/sdb3: UUID="064d9848-ad9a-48fa-bd9c-ebe71d14b1d3" TYPE="ext3"

[rreese6]

if you notice that the UUID is the same. this is what is causing your problem. try my method by editing the grub selection....
in grub hit "e" then select the kernal line and hit "e" again.
back arrow until the end of the UUID number...backspace to the "=" after the word root, type in "/dev/sda3" (no quotes)
so it will now read "root=/dev/sda3" hit enter
then type "b" to boot. if it works, then modify /boot/grub/menu.lst
as in my last post.

[SimonT]

Sorry i did not even notice the UUID is the same will try it as soon as I finnish work.

[rreese6]

No worries! Don't be sorry, we are having Fun here...I am just used to Linux for years, so I read everything....the info is not a bunch of alien speak like another OS I used to use...It actually is usable most of the time...Besides I am taking the evening just to hang out and help folks here....:popcorn:

[mikewhatever]

The uuid of sda2 is obviously the same, so that's not the problem. However, if Ubuntu is now on sda2, Grub is looking on sda3 because of (hd0,2). Grub starts counting from zero, so that (hd0,0) is the first partition, (hd0.1) the second, and (hd0,2) the third. I am not sure why you have that line in the menu. I have another uuid instead. However it may be, (hd0.2) points grub to sda3, and the uuid line to sda2.

[SimonT]

I will remove the current drive and take the cloned disk out of the USB caddy and install it and rerun the tests and check uuidd as well as testing whats said here.

[rreese6]

ok let us know how it works out

[SimonT]

Ok removed the old disk and tock the new larger disk out of the usb caddy and installed it.

On boot I received the error 15 at this time it did not allow me to edit my grub menu.

I rebooted with a live cd once logged in I ran blkid


ubuntu@ubuntu:~$ sudo blkid
/dev/loop0: TYPE="squashfs"
/dev/sda1: TYPE="swap" UUID="faa0dea0-9647-4872-b189-df01a91ddbcc"

/dev/sda4: UUID="BC78488E784848FA" TYPE="ntfs"


Will now look to see if I can do a manual edit of my grub menu with the ideas given and reboot and see if I get the menu.

[SimonT]

Crap in the live cd when I tried to use the text editor and save the file I get permission denied


I tried sudo gedit menu.lst but still would not allow me to save it.

Any ideas ?


Will put the old disk back in and keep looking.

[rreese6]

ok that is probably because the disk is mounted as read-only.
what you need to do is unmount it and remount it.


do this with hd in comp and boot off of cd rom


umount /dev/sda3
cd /media
mkdir sda3
mount /dev/sda3 /media/sda3
This will mount the hard drive so it can be written to.
then do this


cd sda3/boot/grub
sudo gedit menu.lst

Save it
then reboot
and all done

[SimonT]

Ok based on the commands above I used this commands


ubuntu@ubuntu:~$ umount /dev/sda2
ubuntu@ubuntu:~$ cd /media
ubuntu@ubuntu:/media$ ls
disk-1
ubuntu@ubuntu:/media$ sudo mkdir sda2
ubuntu@ubuntu:/media$ sudo mount /dev/sda2 /media/sda2
ubuntu@ubuntu:/media$ cd sda2/boot/grub
ubuntu@ubuntu:/media/sda2/boot/grub$ sudo gedit menu.lst


Now at last able to save menu.lst this is what it looks like

Saving and rebooting wish me luck

[SimonT]

No luck still getting error 15 when booting did I miss understand about setting the correct "root" value ?

[presence1960]

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script 0.32 to the desktop. Once on desktop open a terminal and run this command
sudo bash ~/Desktop/boot_info_script*.sh This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.

[SimonT]

Thanks presence1960, I found the link in your sig a little while before you posted and read through the code and thought this would be handy to use/fault find. I am at work right now but will try and do it when I go home for lunch.

No problem. I will check back in the morning. it is 11:00 pm here and I will be going to bed in a little while.

[oldfred]

Some suggestions:

Grub is looking at sda3 but Ubuntu is in sda2 - you need to reinstall grub to correct where it is pointing.

I would change your menu.lst entries for the 3 Ubuntu lines from
root (hd0,0)
to
UUID 0b77b069-d566-4e2e-989a-b68dab3636ee

You could use (hd0,2) but UUID are more current & less likely to change.

You also need to change the windows from (hd0,2) to (hd0,3) since it is in sda4.

[SimonT]

Thank you for the hint oldfred

Will make the change to menu.lst

In my menu I have two root statements I will change the first one but I thought that maybe the second one was a extra hint :-) at the location of the boot files.


One thing that is also strange I was expecting to get a new UUID as I cloned my original disk (I guess a UUID is not the same as a diskid)

To reinstall grub is it as simple as

grub-install /dev/sda2
reboot ?

[oldfred]

There are several ways to reinstall Grub. You want to install it to the MBR of your first drive.

Supergrub is the easiest.

If you have chroot the mounted partition (chroot ubuntu) then you can
grub-install /dev/hda

sudo grub
find /boot/grub/stage1 #you will get a response such as root (hd0,1)
root (hd0,1) #use the numbers from the previous command
setup (hd0)
# Or
6. Type "setup (hd0,3)". This is key. Other instructions say to use "(hd0)", and that's fine if you want to write GRUB to the MBR. If you want to write it to your linux root partition, then you want the number after the comma, such as "(hd0,3)".
quit

I believe that the reason you have the same UUID is because you cloned the drive. That is so that all the entries are the same. Normally you will not have 2 UUIDs the same.
Hopefully I pointed you the correct way. Presence usually sees something more in the way of things to fix and is clearer on way to fix them.

[presence1960]

This is what I would do. I would first reset GRUB because GRUB is pointing to partition #3 which has no OS on it. To reset GRUB do this:

1. Boot your computer up with Ubuntu CD
2. Open a terminal window or switch to a tty.
3. Type sudo grub. Should get text of which last line is grub>
4. Type "find /boot/grub/stage1". You'll get a response like "(hd0,1)".
Use whatever your computer spits out for the following lines.
5. Type "root (hd0,1)", or whatever your hard disk + boot partition
numbers are for Ubuntu.
6. Type "setup (hd0)", to install GRUB to MBR
7. Quit grub by typing "quit".
8. Reboot and remove the bootable CD.

I would also change these in red

As it turns out this appears to be a very simple problem. That is why I always insist on using the boot info script. If we had run that from the beginning of this thread it wouldn't have carried on for 3 pages.

P.S> according to the output from boot info script all UUID's are unique.

If you want GRUB to take over at boot It must be in MBR.

Your windows is on sda4 so your windows entry should be


# This entry automatically added by the Debian installer for a non-linux OS
# on /dev/sda4
title Microsoft Windows XP Professional
rootnoverify (hd0,3)
chainloader +1

Thanks presence for your help and every ones else's hints and ideas.

After following the detail's I was able to reboot and have the grub menu come up. Windows would not boot as it could not find hal.dll. So back in to the live cd and changed the windows boot.ini to point to the correct partition and rebooted and I had windows and Ubuntu running again.

That script was the real key to understand what had happened when I cloned the system :-)

Glad you got it working! Enjoy Ubuntu.
