Cleaned up 12.04 grub lost access to 11.10

**darkod** · May 6th, 2012

Did you do any other changes regarding 11.10? Can it be the grub2 is pointing to the wrong place?

If you can, it's best to run the boot info script from the link in my signature. Post the results as explained there. It will show many details and it will be much faster then guessing like this.

You can run it from your 12.04 which still boots, or from live mode.

One thing is for sure, the /dev/sdb2 needs to be commented out or deleted from fstab because you deleted that partition and it no longer exists. So it can never be mounted by fstab.

At this point, I can't say for certain what, if any other changes have been made. But here is the new output of bootinfoscript:

Code:

Which way are you booting 11.10? It looks like the grub installs in both sda & sdb boot sdc7 (UUID as shown).

You also have entry in the menu for booting from sdc which boots 12.04 in sdc10. The menu entry for 11.10 does not mention version but just kernel version. If this is the most up to date I would try it.

Have you tried all 3 ways to boot?

I now looks like you only have swap on sda.

**darkod** · May 7th, 2012

OK, first of all you have some kind of grub2 with embedded files on both /dev/sda and /dev/sdb.
The grub2 on /dev/sdc looks good and from 12.04 LTS. I would try to use this grub2 and I don't think you are using it right now since you needed to run update-grub to add 12.04 to your boot menu. So, go into BIOS and set the /dev/sdc disk, 1TB, to be first boot option.

That should give you a fully working boot menu with 12.04 as main option, then with 10.04.3 and 11.10, and one 12.04 install on sdc9 which seems broken.

Try that and try whether it can boot all three systems without any problem except the 12.04 on sdc9 which I am not sure can work right now.

Lets see what happens.

**Oldhacker** · May 7th, 2012

Sad to report that when I went in BIOS the 1TB disk already was set to be my first boot option. (It was easy to determine which HD that was as my other two physical HD's are from the original computer construction and are of much smaller capacity.)

For information purposes, I tried booting into the first entry for 10.04.3 and that worked. Unfortunately, there is nothing there that I need.
All my important files and applications are on 11.10 and going to Devices from 12.04 shows that everything there is still intact. All I need is to be able to access them.

I have been a real pest, haven't I?

**oldfred** · May 7th, 2012

And if you boot this entry what happens?

Ubuntu, with Linux 3.0.0-19-generic (on /dev/sdc7)

**darkod** · May 7th, 2012

So, the default 12.04 and the 10.04.3 work. As oldfred beat me to it, what happens if you try the 11.10 from sdc7?

Also, you might try booting the 12.04 and running
sudo update-grub

to see if it will recreate the grub.cfg better. But the current one looks OK, everything seems correct. This might be something related to the 11.10.

**Oldhacker** · May 7th, 2012

Running sudo update-grub ended with the following encouraging lines:
Found Ubuntu 10.04.3 LTS (10.04) on /dev/sdc5
Found Ubuntu 11.10 (11.10) on /dev/sdc7
Found Ubuntu 12.04 LTS (12.04) on /dev/sdc9

A little strange that it found 11.10 on /dev/sdc9 instead of on /dev/sdc10

In any case, trying for 11.10 on /dev/sdc7 brought up the same black screen with a blinking cursor.
Trying the first 10.04 on /dev/sdc5 gave a page of data running fast on a black screen and then went into 10.04.3 just as before.

It is a "puzzlement"

**darkod** · May 7th, 2012

I noticed something in the fstab of sdc7.

Boot your 12.04, open sdc7, open /etc/fstab and look into the line specifying the root partition.

Instead of the options users,user put errors=remount-ro.

So, at the end it should be like:
UUID=XXXXX / ext4 errors=remount-ro 0 1

I guess you put the users,user there because in the install by default it's the above option.

Save and close the file after the edit. Restart and try booting 11.10 from sdc7.

And in your last post you made a small typo, there is no 11.10 detected on sdc9, but there is 12.04 detected on sdc9. I mentioned that, but that will be easy to sort out once you get your 11.10 going.

We are waiting further info about the above try.

**Oldhacker** · May 7th, 2012

It worked! IT WORKED!! YOU DID IT!!!

If Y'all were a little closer to Texas, I'd take everyone who helped to lunch!

Thanks again (I won't upset the results by doing any more editing unless I am exactly certain what i am doing)
