Please add the exact error you are getting from F9 key. If it is too much to type, add a picture.

Do you have any recovery mode/etc from grub? OFten there is a root shell, you can use that to set your password.

Just as a note:
Posting an actual email on a forum like this is a very very bad idea. You are actually giving the whole world your email address and I suggest you edit that post immediately if possible to obfuscate it so the bots don't start spamming you forever. It may already be too late.

If you can't edit it then report it and ask the moderators to do that for you.

As far as I know, there is no root password by default on Ubuntu
User created during installation only have "sudo" rights

So, it's your user password
