Ubuntu 10.10 booting problem after using Gparted

[sebas2831983]

Hello everyone,

Ubuntu 10.10 worked great until I created a FAT32 partition with Gparted. While booting Ubuntu, it fails with the following messages:



Begin: Loading essential drivers ... done.
Begin: Running /scripts/init-premount ... done.
Begin: Mounting root file system ... Begin: Running /scripts/local-top ... done.
Begin: Running /scripts/local-premount ... done.
[ 3.644823] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
Begin: Running /scripts/local-bottom ... done
done.
Begin: Running /scripts/init-bottom ... done.
mount: mounting /proc on /root/proc failed: No such file or directory
init: Error while reading from descriptor: Bad file descriptor
init: hwclock main process (314) terminated with status 127
init: ureadahead main process (315) terminated with status 3
/bin/sh: Can't open /proc/self/fd/8
init: mountall main process (316) terminated with status 127


I guess (not sure, I'm a nube) mounting the hard disks goes well, however, something goes wrong with mounting /proc on /root/proc. As I understood, /proc is some kind of virtual drive kind of thingy.....

I have no idea how to solve this. For you information, I just booted Ubuntu 10.10 from the 'live cd' and navigated to the physical hard drive, where the 'installed version' of Ubuntu 10.10 is located. The identification of the devices read:



sudo blkid
/dev/loop0: TYPE="squashfs"
/dev/sda1: UUID="9c30c37f-81ae-4423-a660-20318be12e52" TYPE="ext4"
/dev/sda3: UUID="D477-5BE7" TYPE="vfat"
/dev/sda5: UUID="b715c668-22a9-4a24-af8c-54d9d4a95e96" TYPE="swap"


Whereas the fstab file looks like:



# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
/dev/sda1 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=b715c668-22a9-4a24-af8c-54d9d4a95e96 none swap sw 0 0


Does anyone has a suggestion to solve this booting problem?

Thanks a lot!
Kind regards, Bas

Lets see that information and a little more click on the bootscript link in my signature and run it and post all the text from the generated file in code tags.

Did you try to resize the sda1 partition while using it? or resize it at all, and from which end the front or back?

Hi Wilee, thanks for your reply!

Considering your last question, I booted from a Gparted cd, so I guess I did not using sda1 at that time. Then I resized the partition from the back. With that appearing space, a FAT 32 was created.

Hope this gives you enough information. Anyways, thanks again!

You have no bootloader in the mbr, this link will give you the two commands to fix this.

The only other thing I see with a quick look is this.

This should be taken care of with a reinstall to the MBR of the drive. That message usually appears when GRUB is installed to the partition rather than the drive.

Thanks I wondered about that.

[Rubi1200]

No problem, wilee, you are welcome.

Just want to clarify my previous comment; when one attempts to install to the partition.

[sebas2831983]

Thanks a lot guys, I'll have look at it this afternoon. I'll keep you informed.

So I've been working for a while on the suggestions above. Grub was installed by the following commands:



sudo mount /dev/sda1 /mnt

So, it reads that Grub 2 is now installed in the MBR. After checking several times (adding some commented (#) text lines to the grub.cfg file), the grub.cfg file has not been updated during the installation of grub. (You may find the grub.cfg file in above displayed boot info summary.) Is this normal?

I also wonder about these lines in the grub.cfg file:


insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
Why does it consider ext2? Since the partition with Ubuntu deals with ext4, right?

I hope this gives some new insights. I would be very happy to hear from you guys.
Thanks!

Hi & welcome to UF

The core image thing not being found is what concerns me. It may help if you edit your fstab like this...

Change this line...

/dev/sda1 / ext4 errors=remount-ro 0 1
To this...

# /dev/sda1
UUID=9c30c37f-81ae-4423-a660-20318be12e52 / ext4 errors=remount-ro 0 1

You don't run the update grub until you're back in the install.

In these sort of circumstances I generally use supergrub2 to get in then just reload grub from the booted install.
http://www.bootproblems.com/

commands once in would be..
sudo grub-install /dev/sda
then
sudo update-grub

Not sure what you mean by "(adding some commented (#) text lines to the grub.cfg file)" you might want to elaborate on that as grub2 has a specific editing protocol.

There is also this thread on purging all of grub and reinstalling it.

Hi Dutch70 (somehow related to the dutch language :) ?),

THanks for your suggestion. I changed it into your recommended UUID. Nevertheless, similar error message about /proc while trying to boot .

What to do?
Bas

[Dutch70]

Hahaa, not related to the dutch language. Just a nickname.

I think your problem is related to this line in your boot info script, but after that, it's beyond me.

Grub 2 is installed in the boot sector of sda1 and
looks at sector 34023240 of the same hard drive for
core.img, but core.img can not be found at this
location.

I would take a look at wilee nilee's link to purging and reinstalling grub2 first. Seems that would be easiest, for me anyway, b/c I have no idea about supergrub2.

Btw, these are not a problem.
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'

[sebas2831983]

Hi wilee-nilee,

I tried supergrub2 serveral times, it finds grub stuff, but in all options booting fails with the same /proc mounting error as mentioned before.

Then I tried to follow the "HOWTO: Purge and Reinstall Grub 2 from the Live CD" guide, following the steps related to 'chroot', namely trying to chroot-ing stuff into the installed OS, while being into the 'live-ubuntu-system'. So, I followed step 1C, something with mounting stuff temporarily. The line


for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt/temp$i; done
is equivalent to:


sudo mount --bind /dev /mnt/temp/dev
sudo mount --bind /dev/pts /mnt/temp/dev/pts
sudo mount --bind /proc /mnt/temp/proc
sudo mount --bind /sys /mnt/temp/sys
But here, again problems with mounting /proc , namely:


mount: mount point /mnt/temp/proc does not exist
The other three mount commands work fine I guess... when I run the command, I get no responses:


ubuntu@ubuntu:~$ sudo mount --bind /dev /mnt/temp/dev
ubuntu@ubuntu:~$ sudo mount --bind /dev/pts /mnt/temp/dev/pts
ubuntu@ubuntu:~$ sudo mount --bind /proc /mnt/temp/proc
mount: mount point /mnt/temp/proc does not exist
ubuntu@ubuntu:~$ sudo mount --bind /sys /mnt/temp/sys
ubuntu@ubuntu:~$

... guess that's alright?

I'll try to find a topic on this specific mounting of /proc . It's all new to me, so I doubt it to find a solution.

Guys, any thoughts are most welcome!

Cheers, bas

[sebas2831983]

So there is probably no /proc directory.... how come? When I browse through the files of the installed system via the live-system, I just can't find the /proc directory. Well, reinstalling sounds like the best option, isnt it?
Bas

[sebas2831983]

Hello all, after manually making a /proc directory I managed to boot ubuntu. I could log on, but then autohority warnings appeared and nautilus could not be loaded. From here, I decided to do a new clean install of Ubuntu, since further editing file permissions is somewhat tricky for me. Besides, I dont trust the system security anymore in that case.

I've learned lots of new stuff this weekend, with the help of you guys. Again, thanks for your help! I appreciatie it!

Best regards, Bas

[Rubi1200]

It's a pity you needed to do a clean install, but in this case it was probably the right thing to do.

Good luck and enjoy the experience :-)

[Dutch70]

I just want to add that now may be a good time to create a /home partition if you don't already have one. Then you'll be able to reinstall without losing your data or settings, and you won't have to worry about upgrading anymore.

Also, please mark this thread [Solved] with Thread Tools at the top of the page.

[sebas2831983]

Okay, thanks for the /home suggestion. Everything is running well again guys, thanks again!
Cheers, Bas
