Hello, I have Lenovo Ideapad Z570, the moment i strike F2, password prompt come and i dont have the password. I tried many password software, it executes successfully n after reboot I get a Checksum error, then I press F2 again to get the same password prompt, I cannot get through it, it looks its a supervisor password, any help.

If you never set a password, then it be per-protected. you may send a mail to Lenovo informing about this issue.
