So, this is my problem with backtrack4:

I use arch, and wanted to have backtrack 4 pre final installed as well, so, as i had to reinstall all my system, i also installed bt4 first, in one single partition, and then, arch with /boot and /home in different partitions.
The thing is that now, i cannot boot into backtrack, and only boot into arch.
My question is: How can i add a new entry in my arch grub boot menu so i can boot into bt4? Like some kind of dual boot with two linux distros.....

Thanks!
