Question error: unknown filesystem. grub rescue> (how can I use window 7 again??)

Hello I'm new to this OS "backtrack 5"
recently I installed BT5 (backtrack 5) on my laptop dual boot with window 7.Today I want to remove BT5 out off my laptop so I use Aomei Partition program to delete a partition where I installed BT5 and I merge it to drive D: (normally I use C: as window 7 and D: for storage data) the partition program ask me to reboot the window to perform the task (merge partition),Then when my laptop boot up it ask me to select OS between BT5 and window 7 as usually when I boot my laptop. After I select window 7,partition program begin to merge the partition.While in progress the error occur and show this message
error: unknown filesystem
grub rescue>

How can I fix this problem? and continue using window 7 ??
