The best way to get help from me is to start over. Re format the partitions. Recreate the file system. Tell me which guide you are following specifically. Install backtrack as instructed in the guide and then when you get to a error point ,stop post the error and I or any number of people can help. It is imperative we know the method and the error. it would also help to know if you are dual booting or are you just trying to install backtrack
