I haven't gotten to working with the SSD yet, but I just checked the
boot HDD in the notebook, a Seagate 500GB drive, and it has no front
end partition for the EFI.  The first partition starts at sector 2048,
like almost all the ones I've ever seen do, and it is type Linux (83)
marked 'boot':

$ sudo fdisk -l /dev/sda
Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0xfd137519

/dev/sda1  *            2048   63999999     63997952   30.5G   83  Linux
/dev/sda2       64000000   71999487       7999488      3.8G   82
Linux swap / Solaris
/dev/sda3       71999488  976771071  904771584  431.4G   83  Linux

There also is no /sys/firmware/efi directory, and I have UEFI enabled
in the boot PROM.

$ ls /sys/firmware/
acpi/  dmi/  memmap/

Does an SSD require the EFI partition where a hard drive does not?  Confusing.

Thanks.
