I read the link you posted which mentioned that Ubuntu has a "key" in the boot loader...
also note my comment in my last post:

Redhat's "shim", and Ubuntu's "making them (UEFI) talk", were both references to them having Secure Boot "keys".
Installing Ubuntu with UEFI
on and then turning UEFI
off WILL play havoc with the boot loader, as it is setup for one way, and then you suddenly change the hardware, without changing the software configuration.
The "boot loader" simply "takes over" from the BIOS, and lets you choose which "OS" you want to boot. It's not a complicated, self (automatic) configuring piece of software.
ULTIMATELY, I think that Reece's booting issues are simply that Ubuntu failed to
INSTALL the boot loader. Because, for what ever reason, it was unable to write to the MBR on the Primary Hard Drive.
I think he may need to re-install Ubuntu. Which shouldn't take too long.
