boot failure after kernel update

[jtmedin]

Its getting so i do not suggest ubuntu to my friends. It started several months ago on my tower. After a kernel update ubuntu would not boot. So found this procedure using the live update cd. Update grub.cfg & delete everything down to but not including the first line that starts with 'menuentry' . Then boot works ok. A couple of weeks ago it started on my notebook. Is anyone @ hq listening & able to fix this problem permanently? Or am i doing something stupid? TIA

If a new kernel doesn't boot and you have only Ubuntu installed on the drive, hold down the shift key whilst booting and the grub menu should appear (on later versions). Instead of booting the latest kernel choose an older kernel and boot that.

[drs305]

You most likely aren't doing anything wrong if you haven't tinkered with the grub scripts. By removing all the lines prior to the first menuentry you are essentially taking many of the grub scripts out of play. (It may even have been one of my posts that recommended this procedure. ;-) ).

Although there have been updates of most versions of Grub2, it is possible you have something wrong with one of the Grub2 files.

I would recommend booting into your normal Ubuntu system, ensuring you have an Internet connection, and then purging and reinstalling Grub2. It's been very stable for most people and you shouldn't be having problems. By purging rather than just reinstalling, you will be ensuring that any damaged file or file moved/renamed/deleted by you is returned to its original status and location.


sudo apt-get update # Ensure you have a working Internet connection
sudo apt-get purge grub-common # Purges grub-common and grub-pc
sudo apt-get install grub-pc # Installs grub-common and grub-pc

As it reinstalls, you will be asked about kernel options. Tab to OK if you don't add any special instructions to the kernel line.

When asked where to install it, select only the drive; do not select any of the partitions. Select the drive with the spacebar, then tab to OK.

Reboot.

+1 on Quackers:
From an article I read by Linus Torvalds there are 10,000 lines of code added daily
and 5,000 removed. To have an occasional boot failure by a new kernel trying to adapt
to so many different versions of hardware and drivers is not that bad. That is why you
should keep 2 or 3 different kernels installed to boot from at all times. I think it is fantastic
that the rate you actually get a boot failure from a new kernel being upgraded as often as
they are is remarkable in itself. There is a learning curve when starting Ubuntu linux just as
there was when someone started using Windows or Mac. I have used all 3 and prefer Ubuntu Linux and am proud of it being what it is.

EDIT: I see you have drs305 in your thread, there are a lot of good tutorials out there but in drs305 signature there
are a few that are nice, put them in your bookmarks and read them as time permits and practice using code until you understand
not only the code but the why. Also find one on dpkg command will help in some occasions. Linux really is remarkable
if you have the want to learn. Enjoy your Ubuntu and do tell your friends to give it a go, they might thank you one day.

I agree about keeping and trying an older kernel, but if the OP is editing grub.cfg and only removing everything prior to the first menuentry then Grub would still be booting the same kernel entry unless he has modified the default settings in /etc/default/grub.

I agree about keeping and trying an older kernel, but if the OP is editing grub.cfg and only removing everything prior to the first menuentry then Grub would still be booting the same kernel entry unless he has modified the default settings in /etc/default/grub. Understood and would not update-grub or grub-mkconfig just
make a new /boot/grub/grub.cfg if attempting to edit /boot/grub/grub.cfg would not be
a permanent edit. I imagine as you stated to purge and reinstall grub could only help to
get back to correct grub.cfg and menu entry's.
*I have always purged grub-common grub-pc and installed grup-common and grub-pc
so as per your code I have purged and installed one to many packages not that it harmed
but a waste of time.

[drs305]

@ garvinrick4,

You can put both grub-common and grub-pc in both commands, but due to dependencies you don't have to actually list them both. grub-pc cannot exist without grub-common, so when you remove grub-common it takes grub-pc with it. Similarly, to install grub-pc it has to have grub-common, so the latter is installed as well. It doesn't hurt to include them both for clarity.

The reason I suggest purging in this case is that it's possible there is something wrong in the 00_header or other files which build the first part of grub.cfg (before the first menuentry). Whenever a new kernel is added, update-grub is run and the entire grub.cfg is rebuilt. If there is a problem with the way the file is built, just running update-grub wouldn't necessarily fix it.

@drs305

Thank you for clarifying, enjoy your day.

Sorry i am so late in trying this fix. I have been on vacation for a couple of weeks. Tried to purge & refresh grub but no banana. Got the same no boot & had to delete everything up to the menuentry. Now it boots again. One thing i did wrong is copy all three sugestions to terminal so i got a mishmash. So then did line 2 all by itself & then line 3 all by itself. Only comment i got was delete the grub boot record after line 2. I said yes to that & then did line 3. Got none of the comments your msg suggested?

If the second command purged grub, grub-pc (Grub2) and grub-common, the third command would have asked about where to install Grub2; so something didn't work quite correctly.

You can try running both commands again, one at a time. Or please download and run the boot info script from the following link and post the contents of RESULTS.txt. It will show us the status of your system and boot files.

I think this is the first time we knew you were using Wubi...

Rubi1200 has created a thread devoted to Wubi boot failures. Please take a look at that thread. Determine which problem is similar to yours and then apply the applicable solution.
http://ubuntuforums.org/showthread.php?t=1639198

The followers of that thread are very familiar with Wubi boot failures and I'd suggest you post there so ensure they will see it. You'll probably have to post the RESULTS.txt in that thread.

Ran the bootscript & got the results. Copied same to a reply but dont know what i did wrong because its not in this thread. Tried again but same result? anyone got any ideas? I will try again & watch carefully.

Now i am confused i see all the posts, guess my eyes are failing me :-). Thanks for the tip on wubi will try there.

I am new to Ubuntu, just installed 10.04 LTS through a WUBI install a couple of weeks ago and everything was working great. Then today, I was prompted to install certain "security updates", so I allowed the system to do that. Now I can't reboot. As the system tries to reboot, at the point when asked to select Windows or Ubuntu, and I select Ubuntu, the computer simply tries to reboot again and brings me right back to the Windows/Ubuntu boot selection prompt. I can successfully boot into Windows, just not Ubuntu.
System is: HP dx5150 desktop running on AMD Athlon 3000 chips, Windows XP sp 3, Ubuntu WUBI 10.04 LTS.

GreginSJ,

This is an unfortunately common failure in Wubi after an update. Visit the Wubi megathread. Your problem is described and the solution posted in the first post.
