Rescue boot - Cannot mount vfat partition - /boot/efi System won't boot

[Robin Laing]

Hello,

A Fedora 21 laptop that was working now will not boot.

Fully updated dual boot machine.  Windows quit working but Fedora worked 
until last night.

Trying to boot today, it won't mount the efi partition.  /boot/efi so 
the boot process cannot boot properly.  Grub refuses to boot the kernel. 
  Or any of the kernels in the list.

If I try to mount the efi partition manually in rescue mode, I get an 
error message.

using mount --type vfat /dev/sda6 /boot/efi/
   I get
mount: unknown fielsystem type 'vfat'

If I type in
   mount -t
and press tab, vfat does show up in the list of file system types.

I have searched and found out dated bugs with similar issues but nothing 
current.

One of the lists suggesting help suggested running
   dracut --regenerate-all --force

It didn't change anything.

My options are to re-install if I cannot get the boot fixed.

I reported this as a bug.
