Just further to this, I have checked my boot order in the bios and it

If at boot time I display the boot menu it shows this as SSD, HARD DISK

being the default boot device.
So you do have an EFI system. You're just booting it by default as CSM.
Better not to remove those packages then. :-)
Also in the bios Security section I have Secure Boot explicitly
disabled, and the bios also says that Secure Boot can only be used if
the system is in 'User Mode'.
Why are you mentioning this? Secure Boot is optional for EFI. You can
still boot in EFI mode whether secure boot is enabled or not. But you
can't use secure boot if you boot in CSM mode.
