After deleting the partition on which Ubuntu was installed and enlarging the windows partition to fill the old space at the same time( stupid I know), I am unable to boot to Windows 7. All I see is a command line message that says Unknown File System and on the next line says Grub Rescue> with the option to input commands. After looking at this forum and Ubuntu forums I'm still unable to resolve the issue. I would like to be able to boot into windows 7.
