Help - 11.04 Upgrade broke Grub

[eakergd]

I am working from a live cd now - upgraded last night and I can no longer boot. I have seen other tutorials for fixing this from a live cd, but I have 2 HDDs with Vista on sda (I only use it for gaming - don't look down your nose at me :-) ) and ubuntu on sdb. I haven't seen any instructions on how to fix grub with this configuration. Sda2 is my boot partition, since the original HDD has a hidden partition for reinstalling Vista (sda1).

Could someone please tell me how to fix grub from a live cd with this configuration? I don't want to lose my Vista partition, and I really need the files on my Ubuntu Home partition, so a wipe and reinstall at this point is not an option. Below is the output of my fdisk -l command. Thanks in advance.

Gary

what do you mean "broke" grub ?

If you mean it dont boot when you select ubuntu boot line, then it might be due to wrong uuid

from a terminal: sudo blkid
will give you the uuids

only edit the grub boot line and change the wrong uuid by the good one, then ctrl+x to boot

If its not the case, then you need to reinstall grub from livecd

[Quackers]

Which hard drive is set to boot first in your bios?

[eakergd]

Sorry I wasn't more specific. What I mean by "broke grub" is that I get no grub menu. When I boot from my hdd, I get a black screen with a blinking cursor in the top left - no grub menu - nothing.

I realize I probably need to reinstall grub from the live cd. I need help with that, please. I have seen tutorials, but they say to mount certain partitions if you have a separate boot partition. Does my windows partition which is set as my boot partition fall into that category?

Do I need to chroot with this configuration? Which partitions do I need to mount?

Which hard drive is set to boot first in your bios?

sda2 is set as my boot partition -- that is where Vista resides.

Click on the boot-info-script entry in my signature and follow all the instructions there to copy the RESULTS.txt file back here.

I am sure that I, or someone else will be able to help you get grub back.

Bump - anyone?

[Quackers]

You didn't answer my previous question. Which hard drive (not partition) is set to boot first in your bios?

The file in red below needs to be removed from the Windows root.


=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #1 for (,msdos1)/boot/grub.
=> No boot loader is installed in the MBR of /dev/sdb

sda1: __________________________________________________ _______________________

File system: vfat
Boot sector type: Vista: Fat 32
Boot sector info: No errors found in the Boot Parameter Block.
Operating System:
Boot files/dirs: /bootmgr /boot/bcd /boot/grub/core.img

You can then boot from a live cd/usb and run the following commands to re-install grub2

sudo mount /dev/sdb1 /mnt
sudo grub-install --root-directory=/mnt /dev/sda
PLEASE NOTE that the above is only good if the first boot device in your bios is /dev/sda (which is the 320GB drive).

[eakergd]

OK, I've been using linux for 2 years now and this is the one stupid thing that continues to drive me nuts. I don't understand the relationship of how linux sees my physical drives - just when I think I have it figured out, something like this comes up to let me know that I don't.

I have 2 drives in the system. Drive hdd0 is the drive that the computer boots off of. On that drive are three partitions. In the first partition is hidden, and is set up as a rescue partition for reloading windows. The second partition is set as the boot partition, and that is the partition that Vista resides on. The third partition is segmented off as a place to store data.

On my second drive - hdd1, which the linux sees as sdb, there are three linux partitions.

So I go into the windows root directory, which I think is the one that appears in nautilis as a separate drive called vista 64. When I am in it, the location bar in nautilis reads /media/Vista64. There is a folder called "boot", but there is no folder underneath it called "grub" and I cannot find a file called "core.img".

If I back up in the nautilis location bar to just "/", there is also a folder called "boot", and under that there is a folder called "grub", but still no "core.img".

So where am I supposed to look to remove this "core.img"?

P.S. I lgrew very dissatisfied with windows and I really like linux, but this is freakin' frustrating. I upgraded windows from 3.0 to XP and never had this crazy problem. Somebody in the linux world needs to get it together if they ever want linux to go mainstream on the desktop. It's hard to tell all my buddies how great it is when (what should be) a simple upgrade breaks my system.

OK, I'm done ranting. Please help?

Thanks.

Here is what happened when I went ahead and tried the grub re-install:


ubuntu@ubuntu:~$ sudo mount /dev/sdb1 /mnt
ubuntu@ubuntu:~$ sudo grub-install --root-directory=mnt /dev/sda
/usr/sbin/grub-probe: error: cannot find a device for mnt/boot/grub (is /dev mounted?).
ubuntu@ubuntu:~$

In your Windows root there should be just one folder called boot. This folder should have a load of Language folders and a BCD file and a BCD.log file and a few others. Do you have more than one folder called boot?
If not, in that folder called boot, is there another one called boot as well?

[eakergd]

That is the folder I went into. It had the BCD log files, but there was no grub folder to be found there. It had all the language folders, too - so that is probably the one I should have been in. Is it possible that the installer deleted the grub folder? I seem to remember a year ago when I switched to 10.04 I had a similar problem and I had to switch back to the old version of grub to get everything working.

[Quackers]

So where was it then? Or is it a secret?

[eakergd]

I never found it -- still can't find it. I think the aliens took it.

[eakergd]

OK, I found that grub folder with the .img files. It is on my partition that has the ubuntu install -- sdb, not sure which partition, though. Looks like my root folder though -- bin, mnt, home folders are all there.

[Quackers]

NO!!! Leave that one!
The file you want to delete is on sda1 not Ubuntu - as stated earlier.

[eakergd]

OK -- but how do I get to sda1 if it is a hidden partition? It doesn't show up in nautilis.

[Quackers]

It isn't hidden from Linux. It shows up on the boot script. Does it show in gparted? I'm not absolutely sure though, how to get to it.
No matter, that can be fixed later with a Windows repair/installation disc. Do you have one?
The sbin probe error may be because core.img is in the wrong place.
You will need to purge then re-install grub following the CHROOT section of the guide below. The partition to mount is /dev/sdb1 and the place to install grub is /dev/sda
As you don't have a separate Ubuntu /boot partition you don't need to mount it.

[eakergd]

OK - grub is fixed. Thank you.

New problem - now it boots to the UBUNTU splash screen and hangs.

So I entered recovery mode and followed the prompts - before I did that, it at least showed the word ubuntu. Now I just get a purple screen and nothing.

Thanks for your help so far.

I have a similar problem on a system with a virgin /dev/sda containing a windows instalation and a /dev/sdb that had contained a Linux Ubuntu 10.10 installation.

My posting on the problem is at: update sets root device in /dev/sdb1's grub.cfg to open hd0,msdos2 to look for grub modules (http://ubuntuforums.org/showpost.php?p=10746956&postcount=1)

Updating a self contained /dev/sdb should not change the config files on sdb to think the root is on /dev/sda2! (especially when /dev/sda2 is a pure untouched Windows system that knows nothing of Linux! (sda1 being an ASUS Windows recovery partition))

Even after correcting that, there are other problems that prevent bringing the system up, which I haven't traced down yet, but this is a configuration type that I think the Ubuntu developers should be testing, and obviously have not been.

mabloom please go to the site below and download the boot script to your DESKTOP and then open up a terminal (Applications > Accessories > terminal) and run


sudo bash ~/Desktop/boot_info_script*.sh

This will produce a results.txt file on your desktop. Please copy the contents of that file and paste them in your next post between CODE tags. For CODE tags click on New Reply (not quick reply)and then click on the # symbol in the toolbar.
This will give a full overview of your current system.
Thanks.
