new mbp 13" and snow leopard

[thenumbersrbad]

okay, so i decided to sell my nephew my new macbook pro (2011) and order a mba for myself.

my problem is, i put the snow leopard disk in my mbp and restarted the machine holding down c....i'm trying to wipe the machine so it looks brand new...but now i'm sure i did something wrong, when the mbp finished with the snow leopard install the login screen starts up and shows my user name and pic but it won't accept any password that i've ever had on the machine.

what can i do??

To create a Clean Install (formerly known as Erase & Install) of Mac OS X 10.6 Snow Leopard (the 29 USD Upgrade DVD is a fully working retail version of Mac OS X and does not need a prior installation of Mac OS X on the Mac), follow one of the following guides:
