It looks like the EFI partition was not formatted properly.Which partitioning method did you use in both cases: manual/guided, using entire disk/largest free space, with LVM... ?
When the error happens, can you drop to an installer shell with Ctrl+Alt+F2 and report the output of the following commands:
anna-install fdisk-udeb fdisk -l blkid -s TYPE /dev/sda* grep "format EFI" /var/log/partman
