I've been trying to install BackTrack 5 R3 from LiveCD on my Samsung M3 Portable external hard drive. I've unsuccessfully tried to repair my Grub using the Boot-Repair tool after getting the "Unknown filesystem, Grub Rescue" message. I've also got Windows 7 x64 installed on my internal hard drive.
I would be grateful if somebody could help me fix this problem.
Here's also the link to the log generated after using the Boot-Repair: http://paste.ubuntu.com/5659210/
