I recently installed Ubuntu 14.04 on the same partition (C:/) in which I had Windows 7 installed. After installation of ubuntu, I see Ubuntu boot options in the grub, along with FreeDOS (FreeDOS shows up for my other 2 partitions, D:/ and E:/, my PC had initially come with FreeDOS and I had installed Windows7 to it) and there is no Windows 7 option.

However my Windows data of C: drive is still visible in Ubuntu as "140 GB Volume" with all the previous data present. Is there a way in which I can recover the Windows 7?

I am providing the procedure I used in installing Ubuntu, and believe the problem would have happened due to the partitioning option

  1. I selected "Do something else" and not "Install Ubuntu along with Windows"

  2. Selected the same partition in which there was Windows (C:/)

  3. Gave it 40 GB of space, there was 70 GB free space in the partition. No other step I performed which I feel could have caused the problem. Please help me out.

I also performed sudo update-grub, but it still lists only linux and freedos systems, and no Windows updates.

Thanks :)

Open a terminal using Ctrl-Alt-T and run this command:

sudo update-grub | tee ~/update-grub.txt

You will need to type in your password. After that runs, try restarting. If it still doesn't work, give us the contents of the file called update-grub.txt located in your home directory.

If it doesn't work please read this post on Ubuntu forum: http://ubuntuforums.org/showthread.php?t=1602835

or follow these steps:

try running this in a terminal to see if you have os-prober:

sudo os-prober

If you get a message saying that it isn't installed:

sudo apt-get install os-prober

If it runs, make sure the 30_os-prober file is executable. This is the file that actually looks for Windows when you run "update-grub".

sudo chmod +x /etc/grub.d/30_os-prober

Then try updating Grub again. If it finds Windows, you will see a message in the terminal as the command runs. Or after you can see the menu entries without booting by running this:

grep menuentry /boot/grub/grub.cfg

Hope it help
