[Bradford] New laptop, cannot mount partitions

Still not right! I've disabled "UEFI" setting in the bios interface, or 
it only allows network boot, choices being IPv4 or IPv6.

That leaves me (in priortiy order I've set:

1. [UEFI: ADATA USB Flash Drive 0.00, Partition 1]
2. ['Doze Boot Manager (P4: ADATA SU650)]

Which in turn raises 2 questions:

1. Isn't an ADATA SU650 an ssd drive (solid state)? I specifically asked 
them not to use ssd and paid the extra!
2. How do I get a UEFI Tux boot loader in there?

I tested to see if the 'Doze had been overwritten to load Tux and got a 
message saying my hdd needed sorting out!

TIA,

Mike
