just a few days ago i purchased a dell inspiron laptop with pre-installed ubuntu 14.04 LTS. i was installing the software center and updating in the software updater and it was just completed upto 85% and then it's just goes unresponsive . after this i tried to shutdown but it won't so i just forcefully shutdowned using the power button.when i restarted it's showing a black screen and it's showing the following-

            GNU GRUB version 2.02~beta2-9ubuntu1.3

Minimal BASH-like line editing is supported.for the first word,TAB lists possible completion. Anywhere else TAB lists possible device or file completion.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


Find root partition

You must know what's your root partition to boot Ubuntu. Try:


Now you can see some disks and partitions. You must list each partition to find where ubuntu is installed. For example:

ls (hd0,gpt3)

If this is your root partition, you can see the directories boot, dev, etc, usr,... When you find it:

set root=(hd0,gptX)

where gptX is your root partition.

Launching ubuntu

Find your kernel image with:

ls /boot

You can see one or more images with names like vmlinuz-3.13.0-29-generic. Now load the last image with:

linux /boot/vmlinuz-3.13.0-29-generic root=/dev/sda1


initrd /boot/initrd.img-3.13.0-29-generic

Now you can boot into ubuntu with


Restore grub

Once in ubuntu, open terminal and write

sudo grub-install /dev/sda

Don't forget update before restart with :

sudo update-grub

Also, you can use a graphic repair tool like Boot Repair.

I hope this help you.
