Dear

I am using fedora 19
Recently i can login as root user
but in case i need i login to root user

Now in my normal user i am unable to access the folders.
I am using duel boot.
Whenever i try to get access of other partition then i needed a password. it was ok.
But now i cant access them and a problem shows like

Could not enter folder /run/media/root/

but in case of root its ok

please give a suggestion .

what are the permissions of /run/media/root ?

/run/media/root would implies that the drive is mounted by root. So of course your normal user can't access it.
Unmount it as root and then mount it again as user.
