I was first running a standalone installation of Ubuntu 14.04. I decided to dual boot with Kali so I allocated 65GB out of my 500 GB hdd by reducing the size of my /home partition.
But when I tried to install Kali Linux the space was shown as unusable. Then I ran Gparted and it showed the 65 GB as part of the extended partition. I didn't know what to do so I installed Windows. At the stage where I had to specify partitions I only saw 435GB available, and I installed Windows by allocating 50GB for it. But now I don't see that initially allocated 65GB for Ubuntu anywhere. I ran disk management and also booted it with both Ubuntu and Kali installation disk but I still don't see the 65 GB partition.
Can you please help me?
