remember theat you have to be root to perform the most steps in this howto.
get a laptop, a usb thumb drive (& internet) (tip: you might already have a computer and internet, when you can read this text)
download the backtrack 4 beta iso, or wget it
cd /tmp && wget http://remote-exploit.org/cgi-bin/fileget?version=bt4-beta-iso
or if the first one does not work, try this one
cd /tmp && wget http://backtrack.unixheads.org/bt4-beta.iso
(if both of them won't start downloading, don't worry and just start “wget” again some seconds later and it should work, or try the unl33t link)
it could take a while, so you could listen to music from soundRENEGADE,
or if you have a fast connection open another terminal and try
mkdir -v /tmp/mu51c && cd /tmp/mu51c && wget http://santa.fnord.cx/mu51c/the_prodigy_-_invaders_must_die.mp3 && mplayer /tmp/mu51c/the_prodigy_-_invaders_must_die.mp3 && exit
make a directory to mount the bt3 iso on it
mkdir -v /mnt/iso && mount -v -o loop /tmp/bt4-beta.iso /mnt/iso
now plug in the usb drive, when there is no other usb device plugged in, it should be sdb.
to find your usb you can use
dmesg
should output
sd 5:0:0:0: [sdb] Assuming drive cache: write through sdb: sdb1
in our case sdb1
mkdir -v /mnt/usb && mount -v /dev/sdb1 /mnt/usb
NOTE: sdb1 should be a vfat partition with a minimum of 2GB free disk space
cp -rfv /mnt/iso/* /mnt/usb
this could take some minutes, so we open a new terminal &
cd /tmp/mu51c && wget http://santa.fnord.cx/mu51c/the_prodigy_-_thunder.mp3 && mplayer /tmp/mu51c/the_prodigy_-_thunder.mp3 && exit
[AltTabTab] into your other terminal again
and finally make it bootable by executing bootinst.sh and follow the prompts (press two times enter)
/mnt/usb/boot/bootinst.sh
now unmount,
umount -fv /mnt/iso umount -fv /mnt/usb
and when BOTH volumes are unmounted, cleanup, reboot and start from the usb
rm -fvr /mnt/iso && rm -fvr /mnt/usb && rm -fv /tmp/bt4-beta.iso
and when you were downloading music, you want to get rid of, also do
rm -rfv /tmp/mu51c && reboot
NOTE: you may have to make some changes in your BIOS to boot bt4 from USB
