Sorry to hear that, I actually never had to deal with a GPT/UEFI system
as I just removed the security and installed as a normal one.
Anyway the guy does say : "This does not mean not being able to fix
grub systems based on UEFI.". So what i'd do in your case is verify
if you can effectively boot with UEFI enabled from the sgb disk
without issue. Then I guess you could assume that you could fix
your boot..
And of course, wait for more feedbacks ! :)
Kind regards,
