an EFI System Partition *must* be a vfat partition. I don't know how you came to have this as an ext4 mountpoint. Does 'sudo fdisk -l' show partitions of type 'EF' (or 'EF00', if GPT) on your system? If you're booting under UEFI, this partition must be there; you just need to find it, and put it into your fstab in place of the current entries.
Oh, I overlooked this line earlier:
