1 TB drive. I've added a 2 TB internal drive, initialized as GPT, and
installed Fedora 22 on it's first 500 GB. The UEFI boot order is set to
boot to Grub2 on the second drive, which lists Fedora and Windows 7 in
it's boot menu. This setup works fine so far.</div>

power supply) connected by an eSATA cable and an adapter, to the one
remaining SATA connector on the IPM87-MP mobo, and with a 2 TB WD SATA
drive installed in the docking station, with the intention of installing
a bootable Ubuntu 16.04 on its first terabyte.</div>

first question is, should the new drive in the docking station be
initialized as GPT or MBR? GPT should work for that drive, but if I was
to get another drive
later and want to use that in the same docking station, is there a
possibility of a GUID conflict when UEFI's boot manager tries to boot
the same entry in the boot order, for the docking station?</div>

initializing the drive as MBR prevent such a conflict and allow
installation of Ubuntu normally, and for it to show up in the Fedora's
boot menu by using Fedora's grub2-mkconfig to detect and include the new OS, and still be able to later
install another new drive in the docking station, without any disk / partition GUID
conflicts, or corruption of the UEFI configuration of the overall system<br id="yui_3_16_0_ym19_1_1463241327467_23902"></div>
