Help, odd boot problems after installing 10.04.1

[aeronutt]

I finally got around to installing 10.04.1 on a partition (clean install, not an upgrade), and it's caused some odd boot problems. Here's what my typical power up sequence is:

- Power on, cursor in top left corner for 10-12 sec, never see grub menu, boots to 10.04.1 with never an option to select other OS's.

then,
- Reboot, grub menu appears, and I select 9.10, and it hangs (black screen).

then,
- Power cycle, grub menu appears, and I select 9.10, and it boots but noticeably slower than before the clean install of 10.04.1.

The above is typical, but not completely repeatable. It does some combination of the above steps sometimes, but not all of them.

A bit frustrating to say the least.

Help please!!!!

FYI, I have Windows XP, Windows Media, 9.10, and 10.04.1 in separate partitions to boot. 10.04.1 is currently in the default (1st) position in grub. (Plus I have a partition set up just for my files.)

(PS, I searched around, but couldn't find this particular set of problems.)

post the output of

cat /etc/default/grub

Also, what graphics card do you have installed?

Also, what graphics card do you have installed?

Thanks for the quick responses folks.
This problem is on a Dell laptop, which is at home, so I'll do this this evening.

What command do I need to run to provide the needed info on the graphics card?

[Rubi1200]

If you can boot into Ubuntu; from the terminal
lspci | grep VGA otherwise from the LiveCD same thing.

[aeronutt]

Here are the results. To be complete, I ran both commands after booting into both 9.10 and 10.4. The cat /etc/default/grub results are different between 9.10 and 10.04. The lspci results are exactly the same.

9.10 "cat /etc/default/grub results":

[Rubi1200]

Ok, the graphics card should not be an issue as far as I know.

However, the discrepancies between the grub files may be the cause of the problems.

If I understood your post correctly, you installed 10.04 after 9.10 right?

What does the output of
sudo fdisk -l show

I think you may need to run either
sudo update-grub or edit the file to the settings you had in 9.10.

Hope this helps.

[aeronutt]

Correct, I installed 10.04.1 on a partition a few days ago. 9.10 has been loaded since its release.

"sudo fdisk -l" shows:

I assume I should run update-grub while running 10.04.1 ? (Also, I assume because I loaded 10.04 after 9.10, that the grub files located in 9.10 won't be used anymore, even when booting to 9.10, correct?)

So FYI, running update-grup while in 10.04.1 didn't change /etc/default/grub, it's the same as posted above.

[Rubi1200]

Hi,
the /etc/default/grub file from 9.10 indicates that you made changes to it.

Have you tried applying the same changes to the file in 10.04 and running the update-grub command?

In the worst case scenario, we can reinstall GRUB so don't be concerned about that.

Also, did you create any custom entries for GRUB on the 9.10 install?

If you can, it would also help if you post the results of the bootscript linked to at the bottom of my post.

[aeronutt]

In 9.10, I changed the grub menu delay time from 10 secs to 2 secs, and used the GUI (can't remember the name of it right now, startupmanager?) to make that change. Otherwise, nothing else. No, I haven't tried to make those changes in 10.04.1.

I'll run the boot-script this evening and post results.

Rookie question, is there any security concern with posting UUID's ?

None that I am aware of.

[bait28]

I am having grub boot problems with my 10.10 beta install. I get the error grub error no such device. I ran your Boot Info program and have results but need some help determining what to do next. Can you help.

[aeronutt]

Here are my results from the boot script. Note, being paranoid, I did a global replace of each of the UUIDs with something else in the form of nnnnnnUUIDnnnnn. Thanks for the help so far!!

Well, I don't see any obvious errors in the bootscript.

Did you create any custom GRUB entries using the templates in /etc/grub.d?

If not, I would suggest a reinstall of GRUB and see if that fixes the problem.

The first method is the easiest, but if that does not work use Method 3: CHROOT:
https://help.ubuntu.com/community/Grub2#Reinstalling%20from%20LiveCD

In your case, make sure to reinstall GRUB to the MBR of sda and to mount the 10.04 partition on sda4.

When finished, don't forget to reboot into Ubuntu and run
sudo update-grub

If you have any questions, feel free to ask.

I am having grub boot problems with my 10.10 beta install. I get the error grub error no such device. I ran your Boot Info program and have results but need some help determining what to do next. Can you help.
Hi, firstly you should really start a new thread since your issues are different.

Beta = bugs, especially at this stage so soon before the RC.

You need to copy and paste the results of the bootscript into a new post and wrap it with code tags as aeronutt did.

Thanks.

Nope, no custom grub entries using templates.
I'll reinstall grub and see if that fixes things. I'm sure I'll have a few questions. :)
Thanks!!

Ok, reloading of grub2 using the 1st method seems to have gone cleanly. I tested by rebooting into each of my loaded OS's, and all is good so far. We'll see if any of the intermittent problems pop up over the next few days.
Thanks!!

[aeronutt]

All seems ok now, so again, thanks for the help. Marking this as solved.

[Rubi1200]

You are more than welcome :)

Glad things worked out for you; enjoy!
