I had Windows 8 and Ubuntu on two different partitions. I was using both the operating systems as per my needs as I had dual booting options. I have now removed Windows 8 and installed Windows 7 in its place. Now when I start my laptop, I do not get an option to load Ubuntu. It directly enters Windows 7.

How do I find out if my Ubuntu OS is safe?
If so, how do I regain the Ubuntu OS?

You can check the following link for a tutorial to recover access to Ubuntu by reinstalling GRUB2: https://help.ubuntu.com/community/Boot-Repair

Basically, you will need to:

  1. Boot Ubuntu from your live CD (or USB)
  2. Install boot-repair:

    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt-get update
    sudo apt-get install -y boot-repair
  3. And finally, run boot-repair and clicking the "Recommended Repair" button.

Good luck!
