I have installed Ubuntu 13.04 on my PC using USB drive.
After intalling Ubuntu-GNOME 13.04 I went and opened the app "Disks" and clicked on the 1st Disk Drive and then on the right side I clicked on the "File System Partition" and by mistake I clicked the button "More Action" and did something and I lost my Windows OS, but I have all the Data , I can see it from Ubuntu file explorer.
When i started my pc after my blunder (wehich I didn't know at the time). It automatically boot into Ubuntu .. and not Windows. :( Please Help Me .. I don't know what to do now .
