Ok, I managed to install bt3 onto my hard drive, and I downloaded grub instead of lilo, since I know already how to use it.
After the login, thou, it begin to load the kernel, but after a while it says:
Kernel panic - not syncing: No init found. Try passing init=option to kernel.
Maybe did I do something wrond in grub settings?
I start to think this is the mai reason, since you already had it and it was effortless leaving it there...
That would have been great, unfortunatly I've already tryed that way, but, guess what? My notebook doesn't allow usb boot... This is why I'm obliged to install it onto the hd...
Thanks for your help pureh@te, and sorry if I ask dumb questions, but I'm trying to learn deep linux...
