just now i already download backtrack 4 r2. i install it with VMware player and i have problem after booting. it shows that "bt login:" then i put the user name "root" then i cant write down the password. i dont know what to do with that even though i press enter then it show "Login incorrect". help me with this. sorry 4 the vocab i really bad in english

It isn't going to show any characters when you type in the password. Just enter in the default Backtrack root password (toor), and hit enter.

hello.i have same problem whith same laptop and backtrack4
i cant see what i enter as pass.any way i enter root for user and toor for pass but i cant login
i see incorect login
thank you for help

DO NOT use the old 4

install 5 release 2 !!!!!!!!

also if you can NOT figure this out all on your own you should NOT BE USING Backtrack

But
if you do want to learn it then
step 1
install 5 r2 and NOT the old 4
step2
PAY for the training courses from "Offensive Security"
http://www.offensive-security.com/in...rity-training/

and fallow the how toos
http://www.backtrack-linux.org/tutorials/
also if you can not change the old how to's to use the current bt then try this

earn a 6 year degree in CS with a minor is computer forensics
then in 6 years install BT

Root login to a GUI is not a good idea, so it is not allowed by default on many distros. Create an unprivileged user and use that for logging into the GUI.

By the way, Backtrack is a distribution made by network and security experts for network and security experts. If you are not knowing these essential security things like not logging into the GUI as root you may possibly not be part of the target audience for this distro. In that case I would recommend to start with a more beginner friendly distribution, like Mint, Mepis or Ubuntu.

i did not give any user name or password to it ,in default i used root &toor to enter......after update...it showing root login is not allowed

Because root login to a GUI is not a good idea and therefor disabled by default. That is why I recommended to create a new user. You can switch to a virtual terminal with Ctrl+Alt+F1 and login there as root to create the new user.
