Your MD5 password contains sed and shell metacharacters, which may be interpolated in your script because $grubPW is unquoted. Quote the entire sed expression to protect the shell from interpreting the value of $grubPW. The shell will variable expand inside of double quotes:

Code:
sed "s=password.*=password --md5 $grubPW=g" /boot/grub/grub.conf

If this still has troubles, show the script segment that allows us to test the failure.
