I don't know how to start a new thread so I am asking my question on this one. Hopefully someone can help me. I finally figured out how to install Backtrack 5 to my hard disc. It was a dual boot with Windows 7. The problem that I had was that after the installation finished my pc would not prompt me which system I wanted at start up. I wanted to start over to try and get it right this time but when I put the live USB in and rebooted my computer it just went to a black screen that said, "grub recovery" I don't have any idea what to do know.
