Ubuntu 11.10 fails to boot

[hub_cap]

I installed 11.10 on a new partition (3rd, Sda8 ) along with WinXp (1st), Ubuntu 10.10 (2nd). 11.10 fails to boot but the other OS's do. I have not been able to determine the problem. When I select 11.10 from the boot menu, the message that image not found. I have updated GRUB several times.

I have installed 11.10 on an external USB hard drive and it boots just fine, along with WinXP and 10.10 on the internal drive, but when I select 11.10 on the internal drive, I get the same error as before. There is a message about the UUID.

Which bootloader are you using? Grub2 on Ubuntu 10.10?
What was the message about the uuid?
Go to the site at the link below, read the instructions on the link near the top of the page on how to run the bootinfoscript, download it, run it and post the output here.

I'm using GRUB2. It does not find the image on /dev/sda8 (11.10)

I have the Results of boot_info_script but I can't upload here. I get message about too many images when I try to add attachment. OK I split into two files. Some BS about URLS, HTTP until I have 15 posts.

I see you have a menu.lst file in the /boot/grub directory of sda5, Ubuntu 10.10. Neither 10.10 nor 11.10 use it and the entries you have won't work.

To clarify, you can boot 10.10 and you can boot xp, correct.
You indicate in your last post that Grub2 can't find Ubuntu on sda8 yet the output you show immediately below that clearly states:

Found Ubuntu 11.10 (11.10) on /dev/sda8

So it should be there on re-boot. You are doing this after booting into Ubuntu 10.10, correct?

One thing I did notice is that you have different uuid numbers for sda8 on the Ubuntu 10.10 grub.cfg file than in the Ubuntu 11.10 grub.cfg file. Compare the menuentry lines for sda8 on the Ubuntu 10.10 grub.cfg and the Ubuntu 11.10 grub.cfg and see the difference That is why I asked you what the exact error about uuid was when you tried to boot 11.10.

I think also that ubuntu 11.10 is using Grub 1.99 while Ubuntu 10.10 used an earlier version. The entries are somewhat different but I don't know how much difference that makes. Post the error message about uuid.

When I attempt to boot 11.10, I get the following:

error: no such device 9bd192b3......
error: no such partition
error : you need to load the kernel first

Press any key to continue.

I do a sudo update-grub with the following response:

The same grub is used on 10.10 and 11.10 so I don't know were menu.lst is coming from.

It's left over from a previous install of another version of Linux or a version of Ubuntu 9.04 or earlier or...I don't know. Ubuntu 10.10 and 11.10 both use what is referred to as Grub 2. As you can see at the top of the resutls.txt file, Grub 1.97-1.98 is in the master boot record. Ubuntu 11.10 uses 1.99. I don't think there are major differences but there are some.

error: no such device 9bd192b3..

If you look at the results.txt file and the grub.cfg file for Ubuntu 10.10, you will see that the menuentry for Ubuntu on sda8 has two different uuid numbers. On the search --no-floppy...line it has the uuid referred to above. On the line below beginning with linux /boot... it has a different uuid number.

Now scroll down and look at the grub.cfg file for Ubuntu 11.10 on sda8 and its menuentry and note that it has the same uuid number for both lines and it begins with 446eb...

Since you are booting from grub.cfg on sda5, you might copy the entry from the grub.cfg on sda8 onto the grub.cfg on sda5. Or you could replace the uuid on the linux /boot... line with root=/dev/sda8. You need to use sudo to make these changes.

If you do that as sudo, save the file and reboot without running update-grub to test it to see if it works. Don't know anything else to suggest.
