Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

With not apperant reason when I booted my computed today I got to a Grub command line screen.

As far as I read it seems that the grub might been defected. I've downloaded the Ubuntu live CD and ran the Boot Repair program, at the end I've got Boot successfully repaired. message with a paste. After rebooting I still don't get my boot loader and unable to get into my Ubuntu installation.

I have not backed up files there which I can't figure how to backup, could yo guys assist me getting back into my Ubuntu installation or at least provide a way I could get files located under my user home folder?

Thanks for any help given.

As for fixing Grub, I'll leave that someone more Grub-savvy. I've had a similar problem as you, but when I repaired from the Live CD, it actually fixed my problem.

Recovering your data shouldn't be too difficult. The general process is as follows:

1. Boot into Live CD
2. Find your storage device
3. Mount your storage device
4. Mount your recovery storage device
5. Copy necessary files across

1. Boot into Live CD

I won't bore you with the steps for doing 1 (since you've already done it).

2. Find your storage device

Depending on how your hard drive is partitioned, it might be a bit tricky to determine which partition is the one you need. My personal preference is to run:

sudo blkid -c /dev/null

That should give you an output that has a number of entries that look like: /dev/sdxX: LABEL="LABEL_NAME" UUID="UUID_HERE" TYPE="FILETYPE"

You're interested in finding the correct drive from information like the filetype and label name. Once you've correctly identified the correct drive/partition, then you want to take a note of x and X (from /dev/sdxX). You'll need that bit to mount your drive.

3. Mount your storage device

Before you mount the drive, you need to create a folder to actually mount to. I suggest you create one in your home folder, such as (~/my_original_drive).

Once you've created that, you will want to run a command that is similar to the following:

sudo mount /dev/sdxX ~/my_original_drive

Replacing x and X from the letter and number derived from the previous section.

From here, you should be able to access your data from the 'my_orignal_drive' folder. Have a look around in there and make sure everything is there as you expected.

4. Mount your recovery storage device

To be honest, you shouldn't need to do much here if you're plugging in a USB stick (the newer versions of Ubuntu Live CD should mount these automagically). If it doesn't, follow the same steps above, but for your back-up device. It'll have a different /dev/sdxX and you'll need to create another folder to mount to.

If the backup drive does mount automagically, it'll be located somewhere under /media/

5. Copy necessary files across

Once you've correctly mounted both your backup and source drives, it should just be a matter of copying and pasting!

Hope this helps!

Thanks a lot, as for backup it seems I'm all set, So I can just format and install Ubuntu on a clean hard drive. Though I'll wait bit longer for someone who might be able to provide a way to fix grub. –  Shahar Galukman Aug 3 '13 at 15:37
