bt denying me root login
hi bt users
i am trying to give my username at login prompt as
bt login: root
i get a response incorrect login
how do i go around this
presently i am typing this thread via recovery mode which gave me a root shell and also took my password
why am i not allowed in normal login?
earlier the root username and toor passwd used to work
but now i am only able to get in using the recovery mode
ok fine i did it by chrooting into the bt4 partition and adding a admin user thru terminal
but still i want to know earlier it was allowing me root login and suddenly it said incorrect login ..earlier i was allowed the root/toor combination.
all i did was i changed the permissions of the folder on which i was mounting the bt4
i am using two linux on two partiiotns...
please quench my query..i am eager
i had faced this problem once when i used to be on ubuntu and i played around with the permissions of /usr
but this problem i am unable to understand
