error unknown filesystem
grub rescue>

i am not able to use windows also

please help me

i want my windows and back track back :(

your system must have been using backtrack grub loader to give you an option to select between both the OS (windows and backtrack)

Now since you have simply deleted your backtrack your grub is missing

This leads to two path


install backtrack and don't remove the harddisk where your windows partition is loaded

just opt for "Install them side by side, choosing between them each startup" at the installation time of backtrack5 and everything should work fine

or

repair your windows 7 to install your missing grub loader. Here follow this link
