access denied to Hard disk (C)

I cannot access my one and only hard drive C: on my Vista Home Ed . I
attempted to change permission on a file and subsequently locked mysel out of
the computer. I cannot do anything. I cannot change user controls, install or
delete any program, switch users or anything. Access is totally denied to the
harddrive. I am the only user with only one user account, my name as
administrator. I cannot access or add an administrator account. Can anyone
help me or offer any suggestions? Please do not recommend changing
permissions because I cannot write to or delete from the hard drive.
Thank
you in advance.
