Deleted master password now it wont let me sign

[rayborghi]

So i deleted my master password and when i reset the computer it asks for the password. Ive typed in passwords and it wont register them. Then it wants me to create a new one and that wont work. It says something about filevault too but i dont remember my filevault password. So i created a new admin account and i deleted login from the keychain and when i restart my computer i get a file with a question mark i think. Im trying to get on my old admin account too if that makes a difference. I appreciate the help

What it says after attempting to get the password is type the master password to reset the users password to unlock filevault

Have a little patience. It will probably take more than a few minutes or an hour for someone to see your post and find an answer for you, especially with such a complex problem.

Personally, as messed up as you have that machine right now (and admittedly without full comprehension of the fragmented details you've provided), I would suggest:

Option 1:
Insert your OS X install disc, wipe the drive, format and do a clean install, writing off all data you have on that drive.

Option 2:
Purchase a new drive - use it to replace your existing drive - install OS X on it.
Purchase an external case to put your old internal drive in. Connect it up to your Mac and see if you can salvage anything. If you used File Vault to encrypt your home folder, the odds of that without the password are slim and none.

If that fails see if this will unlock it:-
