use mount command like this :
mount /dev/sda5 -t ntfs -o defaults /mnt/tmpfs
don't forget to run mount with root access if needed
you can use gfdisk instead of fdisk to have GUID support as fdisk says you can also use parted which have support for both mbr and guid .
did you run blkid command with root access ? because when you run it without root access it gives no output .
