http://askubuntu.com – I was using ubuntu 11.10 with gnome-shell. I installed various useful softwares and ran system update using update manager which ran smoothly and asked me to restart my comp at the end. I restarted it to find that Ubuntu entries were missing from the GRUB bootloader and only memory test and windows are showing up. I took a lot of pain in installing various important softwares and cannot afford a re-installation. Tried to boot from the live cd and installed boot-repair and after running it .. it wasnt working properly .. it was just showing that it was "scanning systems" for more than an hou (HowTos)

[ubuntu] Ubuntu not booting !! 1 year 17 weeks ago

I installed Ubuntu 11.10 alongside windows xp in C drive using a Live USB flash drive. Installation went smoothly and after installation it asked to restart. I restarted and removed the flash drive. It automatically booted into XP without showing OS boot options and did all sorts of check scans and In MY COMPUTER i saw that the 7 GB i allocated to ubuntu is gone.

How to Repair Grub 24 weeks 5 days ago

Yesterday I installed ubuntu 12.04.1.

Note : its a dual boot system along windows 7

At first grub was appearing and i was able to start ubuntu but then i had to switch to windows but windows was not booting when i select windows 7 it jumps back to grub window. So i fix the Windows Boot Loader using repair from windows media and wolla windows started to boot but Ubuntu Grub gone.

It first started when I deleted my partition that had Ubuntu 12.04 on it. Little did I realize at the time that it would destroy all the resources of Grub on it, and subsequently prevent me booting into my hibernated windows. So I made a 12.10 Ubuntu live USB and reinstalled windows bootloader.

I just installed ubuntu 12.04 using a different partition for the /boot (I don't know why exactly I did this, I remembered reading somewhere on the web about this). The thing is that after this operation, the grub is not showing at boot, so the computer is loaded directly into windows.

as title says, this is my first time trying ubuntu.

I dont know what's wrong with my update manager..

It says that the softwares that I installed was broken. Maybe because I force shutdown my laptop, because Ubuntu wont shutdown,showing up desktop wallpaper but not title bar and launcher, but It won't shut down (+that's another bug).

I've just update the broken softwares. the size is 60 to 70 MB..

But It doesn't work.

Hi everyone!

As per the title, i've upgraded my 11.10 install to 12.04, but Grub now only lists Windows XP - there is no option to boot to Ubuntu.

Code: sudo update-grub And i get;

Code: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). Could some kno

Hello, I'm a complete beginner if it comes to Ubuntu/ Linux. Yesterday I installed Ubuntu 11.10 as a dual boot with Windows Vista on my Toshiba Satellite A300. I chose option 'install alongside Windows" and automatic partition. The installation process went fine and I was asked to restart the system, which I did.
