View Full Version : [SOLVED] How to move my installation to another PC ~(ALERT! on old HDD UUID)

I have upgraded my sons PC and the new Mother Board won't take the original IDE drive (SATA Only) so I am left with a situation where I have an IDE drive with an Ubuntu 10.10 system installed that I need to copy over to my sons shiny new upgraded PC.

After a lot of searching around I found these instructions here http://ubuntuforums.org/showthread.php?t=35087 and set about the following actions

I installed Ubuntu 10.10 from a live CD on the system
I ran a tar command to back up the old HDD (as per instructions in the above link)
I copied the resulting tgz file accross to the new HDD via the network
Then I followed the instructions to restore the Ubuntu installation (But not re creating the folders I ommitted as they were already there on the new HDD after the installation) and all seemed to work well until I rebooted the new PC.

I'm now getting an alert on boot up stating
ALERT! dev/disk/by-uuid does not exist message and I'm being dropped into a shell
The UUID specified is that of the original HDD not the new one and I would like some advice on how best to proceed from here. I'm assuming that if I can fix this issue all will be good but I'm left wondering if the new hardware will be detected properly

Any help would be greatly appreciated

Hi and welcome to UF

Lets (and when I say "let's" I mean someone other than me) have a look at your boot info script.

To post your boot info script, boot up to your live cd/usb, download the boot info script from the following link & save it to your desktop.
http://bootinfoscript.sourceforge.net/ (http://bootinfoscript.sourceforge.net/)

Then open a terminal (Cntrl+Alt+T) and run the following command...

sudo bash ~/Desktop/boot_info_script*.sh

This will create a results.txt file on your desktop. Open that file and copy/paste the info between code tags using the "#" symbol in the toolbar of your next post.

To put it between code tags, just click the # symbol in the toolbar & paste it between [CODE] [ /CODE] tags.

Here's how to get the "Magic number" or UUID for any drive in Ubuntu. enter ' ls -l /dev/disk/by-uuid '. This will give you the magic number or uuid to use in the grub.cfg or 40_custom file.

The UUIDs are posted in the boot script along with lots of other info.

You probably have to update grub's UUIDs and fstab's UUIDs. Script will show what to change.

jjww,

Running the script from the LiveCD/LiveUSB that Dutch70 requested in post#2 will give us the data to correct your GRUB UUID references and the /etc/fstab UUID references.

The changes are easy to make - but we do need that data to tell you specifically how to make the two changes.

The Hedge

:KS

p.s. - The two step are to:

* Update grub from the LiveCD/LiveUSB (this gives grub the current UUIDS for the new PC)

* Edit the /etc/fstab on the hard disk with the new UUIDs.

Ok, we need to get the UUID for / ...just to make sure.

please post the output of

sudo blkid

Also post the contents of your fstab.

sudo gedit /etc/fstab

All between code tags.

Well, I was waiting for your post, but it looks like you got offline, so I'll give this a shot anyway.

It looks like you're trying to boot to this UUID for "/" aka "root"
aeff18a3-027e-438f-bbde-98cdba5b8c45

But you're actual UUID is...
dab4c5c0-5042-43b4-9c26-7ab745b7d978

It doesn't look like there is one listed in your fstab, it's just trying to boot to /dev/sda1.

So this is what you need to change in your fstab.
change this

/dev/sda1 / ext4 errors=remount-ro 0 1

To this...

# / was on /dev/sda1
UUID=dab4c5c0-5042-43b4-9c26-7ab745b7d978 / ext4 errors=remount-ro 0 1

It looks like you UUID for swap is incorrect too. Just change it to...

UUID=97075384-c0d3-48a3-b253-318487511b52

To help you understand your fstab (file system table), go here...
What is the Linux fstab and How Does It Work? (http://www.howtogeek.com/howto/38125/htg-explains-what-is-the-linux-fstab-and-how-does-it-work/)

You will probably have to change it in grub.cfg also. Use this command to open it.
sudo gedit /boot/grub/grub.cfg

Then change the UUID for root to the match your fstab.

You really only need to change the one in your latest kernel, you can use Synaptic or Ubuntu Tweak to remove your old grub menu entries later.

Change the part in red to your new UUID.

Sorry, Scrap my last post. I had forgotten to coment out the dev /sda1 line on fstab.
After commenting that line out I now have a different issue.
As part of the boot up process I get an unable to update authority certificate error and a sanity check error.
Once these dialogues are ok'd I get the desktop up and I can log in using the original credentials but the desktop is empty and the original desktop settings are all gone.

It's always possible that I didn't zip up the original contents of the HDD properly but the files all seem to be there on the HDD so I still suspect a problem with the boot up settings.

New boot info script on it's way
Dutch70
April 13th, 2011, 01:29 PM
It's possible that running an update will take care of it also.

sudo apt-get update && sudo apt-get upgrade

go ahead and run that while we're having a look at your boot info script.
I probably should have asked you to run the update first. ;)

I don't see anything wrong with the boot script, try running the update and then reboot.

ps. I could be overlooking something in the boot script, but let's see if the update takes care of it.

Hmm,
I'm unable to run anything when booting up with the HDD and I don't think running the update commands would actually apply anything if run when booted up from the live CD.
From your comments I'm pretty certain that something might have been missed when I zipped up the original HDD so I'm going to have a go at starting again from scratch then follow your instructions once I get back to the point where I have restored the original HDD files.
This may take some time.

Ok, I'm going to ask a friend to take a look at this also. He may have more input or notice something I missed.

If you are not the same user, you will not have the same /home or sometimes just in those who move /home have these errors:

Sometimes there are dmrc errors or permission errors and this has how to correct them:
https://help.ubuntu.com/community/dmrcErrors
#Replace all instances of username with your login name or use $USER
sudo chown username:username /home/username/.dmrc
chmod 644 /home/username/.dmrc
sudo chown username:username /home/username
chmod 755 /home/username

hedgehog, you mentioned that I should update grub from the live cd.
I'd appreciate it if you could indicate the steps I need to go through to achieve this
jjww

Steps taken so far are
1) Installed new hardware including new HDD in PC 1
2) plugged old HDD in to PC 2
3) backed up old HDD in PC 2 by using the following methods


Mount old HDD
Started a terminal session and ran sudo su to get root user
cd /media then ran an ls command to get the name of the old HDD (In this case aeff18a3-027e-438f-bbde-98cdba5b8c45)
then changed directory to the old HDD (cd aeff18a3-027e-438f-bbde-98cdba5b8c45)
Backed up the old HDD by running the following command
tar cvpzf ./johnsbackup2.tgz --exclude=./proc --exclude=./lost+found --exclude=./mnt --exclude=./sys --exclude=./media .
Whilst that was running I setup Ubuntu 10.10 (same version as on orig HDD) on PC 1 using a live CD from LXF magazine taking care to set the user name to be the same as the user name on the original HDD
After setting up Ubuntu I restarted PC 1 so it was running from new HDD and set up a new shared folder. For this share to work an update and a re-boot was needed which took about 10 minuites
Once the backup was complete (I ended up with a 115GB file) on PC 2 I copied the file across the network to the new shared folder on PC 1 (Would probably have been quicker at this point to plug the new HDD into PC 2 and copied the file directly accross using the same PC)
3 hours later file copy was complete and on PC 1 I started a new terminal session as super user and moved the copied file from the shared folder to the root
I then unpacked the file using
tar xvpfz johnsbackup2.tgz and just let that run. It took about 1 hour to unpack everything by which time I was obviously needing to log in as the pc had gone into hibernatin mode. Interestingly enough I noticed that after logging back in I had all the original desktop files and folders so I was feeling pretty confident that all would be good
I switched back into the terminal (It was still open after unpacking the backup file) and gedit fstab making the changes pointed out earlier in this thread and saving them
I then ran
sudo update-grub to automatically make the changes to the grub.cfg file that were needed as pointed out earlier in this thread
Feeling pretty confident I re-booted PC 1 and after what looked like a normal boot sequence I was thrown into a tty1 terminal login prompt.
So I logged in and ran the commands as outlined earleir 2 update the system
sudo apt-get update && sudo apt-get upgrade this ran successfully so I re-booted and was thrown back to a tty1 terminal login prompt
I logged back in and made the changes suggested earlier as follows

sudo chown $USER:$USER /home/username/.dmrc
chmod 644 /home/username/.dmrc
sudo chown $USER:$USER /home/username
chmod 755 /home/username
Re-booted and was thrown back to the tty terminal login prompt again

So now I'm stuck!
If I try to run startx I get failed to load nvidea kernel module aborting and no screens found errors.
If I cn sort this out I think I'll have cracked it!
Any ideas?
jjww
April 14th, 2011, 03:56 PM
The actual error I'm receiving now when runnning startx from the tty terminal is FATAL: Module nvidia not found so I guess I need to install the nvidia module. I'll do some searching to see what I can find out

Add nomodeset on the linux line in the grub menu. Then you boot to a low quality mode that will let you install the nVidia driver.

How to set NOMODESET and other kernel boot options in grub2
http://ubuntuforums.org/showthread.php?t=1613132
I had to do this with my Nvidia 9600GT:
To install Ubuntu, boot from the cd press any key at accessibility circle and keyboard, press F6 and then select the nomodeset option.
USB boot - At the menu press tab on the first option to edit the boot options and replaced the 'splash' option with 'nomodeset'.
then
On first boot after install, press e on getting the GRUB bootloader.
Hold shift from BIOS boot to get menu if only one system installed.
Using arrow keys navigate to and delete quiet and splash and type the word nomodeset in their place
Press Ctrl and X to boot (low graphics mode)

After I installed Nvidia driver (default from pop up) then it has worked without issue.
gksudo nvidia-settings
Or it should be in System>administration>Hardware drivers.
Possible additional things to run once nvidia working:
gksudo nvidia-settings
sudo nvidia-xconfig

oldfred, I worked this out whilst you were posting. Thanks to this page http://askubuntu.com/questions/4662/where-is-the-x-org-config-file-how-do-i-configure-x-there I sussed out that all I needed to do was to get rid of /etc/X11/xorg.conf which I did by moving it to a new file called origxorg.conf re-booted PC and ...

VOILA all is as it was, just as I'd hoped (For the time being anyway:))

Massive thank you to all those who helped me out in this thread.
