Get my Kubuntu back!! [SOLVED]

[leo123]

Hi,

Please assist me in getting my Kubuntu back which is installed on hdd1.

Wanted to try PCLinuxOS so it was installed it to hda1 and now I can't boot to Kubuntu.

So far, none of the boot options for Kubuntu I've tried in the PCLOS menu.lst have worked.

title Ubuntu, kernel 2.6.20-16-generic
root (hd1,0)
kernel /boot/vmlinuz-2.6.20-16-generic root=UUID=8a1b78cd-5ce2-4880-8cfb-e2620daf84ed ro quiet splash
initrd /boot/initrd.img-2.6.20-16-generic
quiet
savedefault

Also tried different variations of “root=/dev/hdd1”


The progress bar in Kubuntu gets so far then stops and a maintenance shell comes up and there's an error message that states:

fsck 1.40-WIP (14-Nov-2006)
/dev/hdd3: clean, 18187/2872320 files, 1478645/5737213 blocks

fsck died with exit status 8


Looking at “HOW TO: GRUB Methods - Toolkit for Installation, Rescue, Repair - Fixing Common GRUB problems” is a little over my head at this point.

How can I boot to Kubuntu again?

Thank you

Re: Get my Kubuntu back!!

Looks like your partition is trashed.
Put a recovery cd, in prompt run a:

sudo fsck -p -y -f /dev/hdxx

Where "hdxx" is the disk and partition your linux is installed.
After that, your /lost+found may have some files, check them and delete if you don't need it.

It looks like your uuid's have been changed and kubuntu's fstab can't find them.

That is no big problem.

Try and boot with recovery mode. You will probably get the same error messages and at the end you will hopefully see something with Control-D. Press Ctrl+D this should load the recovery (root) mode. when that is finished type: startx

In your root mode copy and paste this into a terminal:

ls -l /dev/disk/by-uuid/

This will give you your new uuid's for each partition/drive. Copy this to an editor (kate) for better viewing. Now all you have to do is open /etc/fstab and replace the old uuid's with the new ones for every partition / drive, save. Reboot.

For more reading on UUID:
http://www.penguin.ch/dokuwiki/doku....t#mount_errors

If the above doesn't work (you can't boot into recovery mode) Then use the kubuntu live cd to find your new uuid's (see above). Copy the new list to kate and save it to /home/userpclinux. Boot into pclinux activate your kubuntu partition in the control center then do Alt+F2 type kdesu kate, give your pclinux root password, navigate to your kubuntu partition then /etc/fstab then edit as described above, save, reboot.

I hope this helps

Re: Get my Kubuntu back!!

Fintan,

The UUID's listed here are not the ones in Kubuntu's fstab. Should I put the UUID's listed above in Kubuntu's fstab? If so, how can you tell which UUID belongs with each partition/drive?

Thank you

[Fintan]

Re: Get my Kubuntu back!!

Could you post your results for:

ls -l /dev/disk/by-uuid/

?

Re: Get my Kubuntu back!!

for example:

1bf41332-200c-4452-a36f-d71bd5c367e7 -> ../../hda5

means

UUID=1bf41332-200c-4452-a36f-d71bd5c367e7 is the ID for /dev/hda5 (sda5)
so you replace the UUID in your fstab for /dev/sda5 with the one above.

For good measure you might want to compare the UUID for your root and any other partition you may be booting in your /boot/grub/menu.lst and replace them if needed.

If you take your time it's a piece of cake.

[leo123]

Re: Get my Kubuntu back!!

Fintan,

Thank you for your reply. The following is the fstab file from Kubuntu.

If I understand correctly, changes to this fstab will enable booting to Kubuntu from the PCLinux (which has taken over).

Is this correct?

For good measure you might want to compare the UUID for your root and any other partition you may be booting in your /boot/grub/menu.lst and replace them if needed.

Also, are you referring to the PCLinux boot/grub/menu.lst?

Re: Get my Kubuntu back!!

Could someone PLEASE guide me in the right direction?

the "blkid" command shows the following UUID's, which the majority are not the same as what's posted above.

Which UUID's need to be changed in Kubuntu's fstab?

Which UUID's should be used to make the change?

[Fintan]

Re: Get my Kubuntu back!!

As far as I can see the output from

ls -l /dev/disk/by-uuid/

and

blkid

are identical, which they should be.

You have hda7 and hda8 listed in your fstab but not in the outputs.

Do these partitions exist (doesn't look like it)? If not delete them from your fstab.

As far as which uuid's to use is concerned it doesn't matter as both outputs are identical as far the uuid's goes.
All uuid's in the kubuntu fstab which do not correspond with the output should be replaced. (hda5, hda6, hda1, hdd2)

[leo123]

Re: Get my Kubuntu back!!

Fintan,

THANK YOU, THANK YOU, THANK YOU!!!

For your patience, “spelling out” what needed to be done, and for hanging in there with me until this issue was resolved.

As you suggested, I deleted the entries in fstab and as you stated in a previous post, I just took my time and copied the UUID's you suggested. Thank you for pointing out the output for the UUID's was identical. Obviously, I wasn't thinking and didn't realize that.

Loading Super Grub would have been the next step and I'm glad that wasn't necessary.

As soon as I read your last post, I knew it would work!!! Thank you for “getting my Kubuntu back!”

In a few days, I'll do a little research to find out how to get the bootloader back on the hard drive with Kubuntu and change the boot screen to verbose and change the login screen.

[Fintan]

Re: Get my Kubuntu back!! [SOLVED]

I happy to be of help.

In a few days, I'll do a little research to find out how to get the bootloader back on the hard drive with Kubuntu and change the boot screen to verbose and change the login screen.

Okay. Can you post your KUBUNTU /boot/grub/menu.lst?

As for changing the login screen you can do that in system settings->appearance->kdm theme (or something to that effect. Mine is in german) and choose the one you want.

You can find more at
www.kde-look.org
under kdm themes (login screen) and bootsplash (that is the "theme" that shows your kde loading process).

Download the one(s) you want and You can install them with:
system settings->appearance->kdm theme
and
system settings->login screen

Have fun

================================================== ===========

It is probably not correct from many many attempts at trying to boot to Kubuntu from PCLinux.

Does "default" need to be 1? Also, the Kubuntu entry needs to be changed, doesn't it?

Thank you

Re: Get my Kubuntu back!! [SOLVED]

Thank you for your assistance. KDM Theme wasn't installed, but once it was, I was able to change the theme. That was easy.

There were a lot of updates and after updating, the Kubuntu menu.lst is as follows:

# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
