Hello, I have the following problem upgrading Fedora19 to Fedora 21: After a successful preparation the System Upgrade item is not shown in the grub menu. I execute the commands:

grub2-mkconfig -o /boot/grub2/grub.cfg (this completes ok).

grub2-install /dev/sda (this says 'usr/lib/x86/grub/x86_64-efi doesnt exist. Please specify --target or --directory'

After trying several things I copied /boot/grub2/grub.cfg (which has an entry for fedup) to /boot/efi/EFI/fedora/grub.cfg

This time I get a Fedora, with Linux fedup item in the grub menu. I assume this is the item I have to boot to execute the upgrade. After quite a lot of messages I get the following:

boot-efi.mount - /boot/efi
   Loaded: loaded (/etc/fstab)
   Active: failed (Result: exit-code) since sáb 2014-12-13 12:29:10 CET; 3min 0s ago
    Where: /boot/efi
     What: /dev/disk/by-uuid/CA08-7D51
  Process: 859 ExecMount=/bin/mount /dev/disk/by-uuid/CA08-7D51 /boot/efi -t vfat (code=exited, status=32)

dic 13 12:29:10 localhost.localdomain mount[859]: mount: unknown filesystem type 'vfat'
dic 13 12:29:10 localhost.localdomain systemd[1]: boot-efi.mount mount process exited, code=exited status=32
dic 13 12:29:10 localhost.localdomain systemd[1]: Failed to mount /boot/efi.
dic 13 12:29:10 localhost.localdomain systemd[1]: Unit boot-efi.mount entered failed state.

I login root and try to mount the ESP by hand but I get the same error: unknown filesystem type 'vfat'

The EFI partition is vfat of course. I have an UEFI system also with a bootable Windows 8. It is mounted without problem when booting my Fedora19 system. I am completely lost. Any help will be greatly appreciated.

I am sorry this is not your answer but a handy advice for the next time: replace your harddisk with a new HD and install the new version.Test it first. If something goes wrong, you can just replace the new disk with the old one. format the new disk and try it again OR wait for the next version. IT will spare you a lot of time. I prefer a clean installation.

On an efi system, you want to work with /boot/efi/EFI/fedora/GRUB.cfg

On an efi system, do not use grub2-install. It doesn't boot from the disk, it boots the options in the EFI firmware.

Thanks randomuser, you are right. Much to my embarrassment I knew this some time ago but I forgot it :-(

I had no issues while upgrading from f20 to 21 in one of machines. But still would suggest to backup your data and perform a fresh install of fedora 21. It is worth it. Fedora 21 is much more polished, stable and way cooler than ever before. moreover reinstalling might be faster and easier than fixing some problems. You can get the latest copy of fedora 21 here.

Thanks rat, I have already considered this. In fact, the problem is very similar to a reported and solved bug https://bugzilla.redhat.com/show_bug.cgi?id=1044346

However, this was supposedly solved with fedup 0,8,x and I am using fedup 0.9.0. I have opened a new bug report https://bugzilla.redhat.com/show_bug.cgi?id=1174440

I will wait a few days for a solution. If not, I will just perform a fresh install.
