Hi, I was able to boot Backtrack on a multi-boot usb-stick by decompressing the iso to a folder (%USB-STICK%/ISO/BT5) and by using grub4dos with this menu :
###MENU START
title BackTrack\nPentesting Linux Distribution
kernel /ISO/BT5/casper/vmlinuz --ignore-floppies file=/cdrom/preseed/custom.seed live-media-path=ISO/BT5/casper boot=casper locale=en_GB.UTF-8 keyb=us splash noprompt vga=791-- persistent
initrd /ISO/BT5/casper/initrd.gz
###MENU END
I tried the same with kali by changing the kernel , initrd, and live-media-path to fit and i can boot fine up to the login screen.
there it asks for the username/password, i input "root" then "toor" and it says "Authentication failed"
Do anyone have an idea what's wrong?
