12.04 update - Grub - keyboard and mouse freeze
AMD 64 desktop machine with 12.04 running fine for the last 12 months
Install upgrade from 11.10. - not dual boot
Main hard drive 250G sda where the previous ubuntu versions are installed
Second hard drive sdb 1T storage with most of my data
Updates appeared on friday 31 May (did them on my AMD64 notebook)… I was away and on return did the updates to the desktop on Sunday 2 June
Rebooted and it got stuck in Grub … it would not load ubuntu and froze the keyboard and mouse
I tried to get acces from a live install pen … It ran from the pen
I found Boot-repair and now have the machine up again … but ..
It has done a new install on the sdb1T hard drive
I cannot access the original sda information
when it launches Grub … I cannot use keyboard or mouse (they freeze) to launch previous versions listed
Re: 12.04 update - Grub - keyboard and mouse freeze
I attach the records from the boot repair processes:
Initial repair attempt http://paste.ubuntu.com/5735297/
Repairing the boot record on sda http://paste.ubuntu.com/5746401/
Last attempt via Boot Repair http://paste.ubuntu.com/5746694/
I still cannot accesss the grub menu via the keyboard to choose where to boot
Re: 12.04 update - Grub - keyboard and mouse freeze
Normand; Hi !
Your "bootinfo" file... shows 3 hard drives on your system;
sda has ubuntu installed
sdb has ubuntu installed
sdc as the "data" disk...
You should have set the 1st boot priority as the first hard drive in bios... verify that that is so,
else;
what results when you depress and hold the shift key as soon as the bios screen clears ?
just try'n to help
Re: 12.04 update - Grub - keyboard and mouse freeze
Thanks Bashing-om
sda is original ubunto ... with I suppose previous versions stored somewhere
sdb is my 1T storage disk ... which Boot Repair kindly put ubunto on
sdc is the live pen with Boot Repair on it ... I take this out on re-boot to run ubuntu
pressing 'shift' in boot process does nothing
In the boot menu:
When I prioritise either sda or sdb it launches the same 'old versión'
- Although it says 12.04 in the launch screen and in System Monitor this seems to be confused with 10.10
- Places/computer does not see sda
- System Monitor somehow sees both sda and sdb
- System Monitor shows release 12.04 kernel 3.2.0-48 generic
- Update Manager says it is 403 days since last update and hangs up trying to find Meercat updates
Associated problems:
- keyboard blocked in the grub menu so I cannot launch other versions
- it wil not launch (does not see) alsa mixer
Re: 12.04 update - Grub - keyboard and mouse freeze
Normand;
Thanks for the clarification on drives...
So we want ubuntu version 12.04 on sda;
data only on sdb -- presently all I see is linux OS -> be prepared for bad news ;
and leave sdc out of the picture ...
Priority is to see what is on sdb drive...
boot the live medium, ->try ubuntu mode -> desktop:
key combo ctl+alt+t yields a command line terminal ->
terminal codes:
Code:
sudo mkdir /mnt/part1 #prepares mount point and represents 2nd hard drive 1st partition
sudo mkdir /nmt/part5 #sdb5
sudo mount /dev/sdb1 /mnt/part1 #mount the partitions to the file system
sudo mount /dev/sdb5 /mnt/part5 #sdb5
now lets look at what is on the second drive:
As a starting point:
Code:
ls -la /mnt/part1
ls -la /mnt/part5
when done looking about, (un)mount those partitions- keeps the file system from going insane and/or ballistic.
Code:
sudo umount /mnt/part1
sudo umount /mnt/part5
real aggravated ? Now is a good time to employ "testdisk" and see what can be recovered.
secondly is to get grub -12.04's version- installed onto sda -> when you are ready and willing,
we will proceed.

Re: 12.04 update - Grub - keyboard and mouse freeze
Thanks again Bashing-om
So I've had lunch, got some relaxing music on, sitting comfortably and ready to go.
Writing from the affected desktop with a notebook running beside me if I have problems.
I have a live 12:04 pendrive and a live boot repair pen drive
More information for you before I start mounting and unmounting:
- sdb data partition is intact and all my data is there and accessible... it has always needed to be manually mounted after I launch ubuntu ¿**?
The boot record you see was recorded via the live boot repair pen ... so the sdb data partition was not mounted
Re: 12.04 update - Grub - keyboard and mouse freeze
So for the first instructions I get: ...
norman@norman-desktop:~$ sudo mkdir /nmt/part5 #sdb5
mkdir: cannot create directory `/nmt/part5': No such file or directory
norman@norman-desktop:~$ sudo mkdir /mnt/part1 #prepares mount point and represents 2nd hard drive 1st partition

norman@norman-desktop:~$ sudo mkdir /mnt/part1 #prepares mount point and represents 2nd hard drive 1st partition

norman@norman-desktop:~$ sudo mount /dev/sdb1 /mnt/part1 #mount the partitions to the file system

Stopping here for the time being ... waiting for new instructions or questions
Re: 12.04 update - Grub - keyboard and mouse freeze
Normand; Out standing in that "data" disk is intact !
Install grub - make sure it is correct version corresponding between the pen drive and the version installed onto the hard drive.
I am of a mind to do this in 3 stages;
1. install grub onto sda's MBR
2. mount and remove grub from the sdb "data" disk
3. update-grub from the sda install, as sdb's grub is gone will not be picked up on sda's boot code.
stage 1 : boot the live media -> CLI -> terminal codes:
Code:
sudo mount /dev/sda1 /mnt
sudo grub-install --root-directory=/mnt /dev/sda
Done installing grub onto sda, unmount sda and move onto sdb; stage 2
Code:
sudo umount /mnt
sudo mkdir /mnt/part5
sudo mount /dev/sdb5 /mnt/part5
ls -la /mnt/part5 #to identify for sure the directories containing grub config files (/boot???)
sudo umount /mnt/part5
at this point I want to pause...any others input is welcome !
a) cannot "chroot"into sdb as no operating system is installed;
b) can not run normal "apt get remove grub" commands as will operate on the live medium
c) -> ONLY option I can see is to manually delete the identified grub directories and files present on sdb -
-----------anybody got a better method ?????---------------
stage 3
remaining to be done after grub is removed from sdb is to update grub on the sda install//waiting to get sdb's grub files removed.
what ever it takes to do it right
