Ubuntu 14.10 booting problem

  • 772

Recently I upgraded to 14.10 from 14.04. After booting from boot loader for the first time, the screen goes black and nothing happens. When I restart it again, a screen prompts which shows

Unable to Mount, Press S for Recovery or press M for Manual Recovery

On pressing I was able to go to login. This happens always, what is the solution ?

14.04

  1. Download and burn to cd/dvd a software called [Boot-Repair] from sourceforge.net. Boot your machine to [Boot-Repair disk] and wait for the screen that gives you 2 boxes you can check, check the box that says [recommended repair] and let the software do its MAGIC. When it is done you will reboot and you should be off and running again. This is a FREE software download and works very well.

  2. Test this:

    • Switch on your computer.
    • Wait until the Bios has finished loading.
    • Press and hold the Shift key.
    • Will bring up the Grub menu.
    • Select the line which starts with: Advanced options.
    • Select the line ending with: recovery mode,something like:
    • Ubuntu GNU/Linux, with Linux 3.16.0-24-generic (recovery mode)
    • Press Enter and your machine will begin the boot process.
    • Your PC should display a menu with a number of options.
    • One of the options will be: Drop to root shell prompt.
    • Press Enter with this option highlighted.

    In the terminal run the commands:

    mount -o remount,rw /
mount --all
dpkg --configure -a
apt-get -f install
apt-get update
apt-get dist-upgrade
apt-get autoremove
apt-get install --reinstall ubuntu-desktop
update-grub
apt-get clean
reboot
