This page points to official grub documentation as well as a few tutorials: http://www.gnu.org/software/grub/gru...mentation.html

As far as I know, grub doesn't reset the root password. You can boot into single user mode by adding "s" to the kernel parameters, but some distros require entering the root password when going single user. The best solution is booting from a live CD or USB stick, mountiing your root filesystem and removing the password.

Did this system ever boot or is it a new install?
The error you are getting does not likely have anything to do with a password but improperly configured bootloader. The link below is another to configuring Grub2, specific to Fedora.

https://fedoraproject.org/wiki/GRUB_2

Posting more detailed information would be helpful. Boot any Linux Live CD, go to the site below and run the bootinfoscript. It will produce a results.txt file which you can post here and get some help. There is a link to specific instructions on the page.

the only real reason for that to show up is
You changed something
like you removed partitions or resized one that had the mbr or the /boot partition on it
or tried to reinstall windows or a windows service pack


so
first
WHAT did you change ?

and second WHAT version of Fedora is this ?
ONLY fedora 21 and 22 are supported
