I tried to install Ubuntu, but when I chose the partition on which I wanted to install it, my computer suddenly froze and refused to continue the installation process. So I was obliged to restart it.
But after I restarted I couldn't access Windows 7 that I already had in it. I used the windows 7 CD to access the command prompt then I found that my local drive C: had shrunk in size and got the new name Linux instead of the local drive. I could not install Windows on my heard disk.
I tried Ubuntu without installing it using CD and was surprised to find that the partition containing old Windows 7 is still there and showing its normal size 265 GB. How can I recover my windows 7 installation / partition?
