Boot up problem (maybe)

[brave5213]

yesterday i was transferring all my files to my macbook pro, during the process my machine warned me that the harddisk is almost full. after i finished,i reboot the machine but i can't see either dock or anything. the only thing i can see is left-up corner apple logo.
is there any way that i can solve this problem.
i have : 2.8 MBP 17" unibody mid 2009

Did you reboot again? Have you tried keyboard shortcuts (to open Finder and delete data)

You should always have at least 5GB of free space in your HD

yes i did many many times but i can't even see the finder bar. i can't even use any keyboard shortcuts.
