GRUB Problem - Ubuntu 10.04

[andddlay]

Hello! I am aware there are several threads about this - I have been reading them, and they still haven't seemed to help.

Just last night I installed Windows 7. Grub then disappeared, and now I'm trying to get it back. I have found where the /boot is (I believe...), and that is (hd0,6) for me. I then tried:


grub> root (hd0,6)
grub> setup (hd0,6)

In the end of a bunch of fooling around, I boot up my computer and get the following:


[Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename.]
grub>

From there, I tried root (hd0,6) and setup (hd0,6) and it returns saying that stage1 and stage2 exist, and the installation of them succeeded...Done.

Could somebody please help me? I am unable to access neither Ubuntu nor Windows :\.

I have a live CD handy.

Thank you!

Hi,

boot your computer with the LiveCD and click on the link at the bottom of my post.

Follow the instructions there and post the results back here please.

From the grub prompt it is:
grub> set root='(hd0,6)'

If your / partition is there, you can try and boot directly into Lucid from the grub prompt using the following commands:


set root='(hd0,6)'
linux /boot/vmlinuz-version root=/dev/sda6 ro
initrd /boot/initrd.img-version
bootwhere version is the kernel version eg: 2.6.32-23-generic

If it works, re-install grub using either Synaptic or:


sudo apt-get install grub-pc grub-common

Or, re-install the bootloader using:


sudo grub-install /dev/sda

And now update grub's configuration file:


sudo update-grub


If the above did not work, boot from the liveCD and re-install from there Synaptic or the above command.

Firstly,

why do you have GRUB-legacy installed to the MBR? Recent versions of Ubuntu use GRUB2.

Second, you have 2 Ubuntu partitions with 2 swap partitions?

I recommend you wait until one of the more experienced forum members comes along with some advice/solutions.

Meantime, hang in there!

:)

Lol me downloading GRUB-legacy was part of my fooling around to see if I could get it to work...and yeah, my partitions have been screwed up for a looooong time. haha.

[YnotStrebor]

(I just posted this on another similar GRUB thread)

Might be related to a problem I had when I was dual-booting WinXP & Ubuntu 9.10. WinXP was on the primary partition, with temporary files, programs, documents on separate partitions. Then I added Ubuntu. For some nutty reason I decided to put the Ubuntu & swap partitions towards the end of the disk, with a great big, empty, unformatted, unused partition in between the Ubuntu and Windows partitions. Installation was fine... however...

This resulted in GRUB2 refusing to work properly (no menu options). Couldn't boot Ubuntu or Windows from GRUB. However, I could boot either Linux or Windows, but only if I used a floppy disk bootloader other than GRUB.

Realised that GRUB2 wasn't seeing the Ubuntu partition - it could see up to the unformatted gap then no more. The problem was solved by placing the Ubuntu Partition directly after the Windows partition, no gaps, no other partitions in between.

As a backup operating system to browse the net to find a solution to the problem I used Puppy Linux. The advantage with this is that it runs entirely off a CD (leaves your hard disks nice and pristine) and seems to be able to detect enough hardware & graphics cards.

[YnotStrebor]

Oh, and yes, I too tried using GRUB legacy when GRUB2 failed to work. Not that it helped, but I was getting a wee bit desperate.

[drs305]

I think the easiest thing to do would be to boot from a recent LiveCD and reinstall Grub2 unless you have a reason not to use it. It should work for you.

You have sda7 and sda8 installs, so if you want sda8 make the change below.


sudo mount /dev/sda7 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

Note when you get to the partition selector, choose sda and NOT sda7.
Grub 2 will be put in the MBR of sda and the files installed to sda7.

Also, this will be the last time you see all the partitions listed when you install Grub 2. A change to Grub 2 this week eliminates all the devices and partitions except /, /boot, and /boot/grub as choices for the install location. That should go a long way in ensuring it doesn't get installed on a Windows partition and make Windows unbootable.

Added: You have a lot of older kernels in some of your distros. If you want to get rid of them, Ubuntu Tweak is a great tool. More information on it and removing older kernels in the "SUM" link in my signature line if you are interested. About 2/3 of the way down the original post.

[libssd]

Hello! I am aware there are several threads about this - I have been reading them, and they still haven't seemed to help.

Just last night I installed Windows 7. Grub then disappeared, and now I'm trying to get it back. I have found where the /boot is (I believe...), and that is (hd0,6) for me. I then tried:



In the end of a bunch of fooling around, I boot up my computer and get the following:



From there, I tried root (hd0,6) and setup (hd0,6) and it returns saying that stage1 and stage2 exist, and the installation of them succeeded...Done.

Could somebody please help me? I am unable to access neither Ubuntu nor Windows :\.

I have a live CD handy.

Thank you!
1. Read/study this, and print it out: https://help.ubuntu.com/community/Grub2

2. Boot from LiveCD, and apply knowledge gleaned from #1.

3. You may need to re-install Ubuntu.

[oldfred]

drs305, your written instructions are correct but is not your code showing install to sda7 when it should be sda as you wrote?

sudo mount /dev/sda7 /mnt
sudo grub-install --root-directory=/mnt /dev/sda


If grub does not install to the windows partition, many of us here on the forum will not have anything to do.:wink:

[drs305]

Yes, and I've done that before!!! ](*,)

Thanks for watching out for me. I even wrote not to do that in the post!!!

[MrCloudHands]

I'm having the exact same problem as the OP!!! I installed Windows 7 and have been trying to recover Grub, but now I get stuck on a screen that says "Minimal BASH commands..." (can't remember it all) &
"grub>"

Here are the results of the script posted in this thread. Any help would be immensely appreciated!

I'm having the exact same problem as the OP!!! I installed Windows 7 and have been trying to recover Grub, but now I get stuck on a screen that says "Minimal BASH commands..." (can't remember it all) &

It appears you still have Grub legacy installed (according to the boot info script results), with the normal Grub 2 files in your system partition. That could be an anomoly with the script. I don't keep up on Grub legacy any longer, but since you have formatted your partition to ext4 I suspect you need to use Grub2.

In any case, use the instructions in Post 9 to either install or reinstall Grub 2. In your case, use sda1 in the first command.

I also note that the boot flag is on the Ubuntu partition rather than the Windows partition, which may cause problems with that other OS.

Thank You!!! It worked like a charm by following your steps, then just had to change the boot flag in GParted from linux to windows partition.
