Be very careful about what filename you specify in dhcpd.conf if you get an error like this:
NBP filesize is 0 Bytes PXE-E23: Client received TFTP error from server.
If you specify "BOOTx64.efi" then the file had better not be called "BOOTx64.EFI" as it is case sensitive. It's really a case of the file technically not existing.
You can verify this by checking your tftp logs:
routerOS in.tftpd[169277]: RRQ from 192.168.1.193 filename /BOOTx64.efi
Then check the actual name of the file:
BOOTx64.EFI efi EFI grub.cfg images ldlinux.c32 libutil.c32 menu.c32 pxelinux.0 pxelinux.cfg syslinux.efi
Whoops .EFI != .efi so let's fix it and then we boot OK:
mv BOOTx64.EFI BOOTx64.efi
