So I've had a browse around and haven't found any other posts similar to my situation. I've tried to do an overwriting install (erase hard driver and install Ubuntu) of Ubuntu 12.04 (64 bit) on my Toshiba Z930 but it won't boot passed bios. I never see Grub, only a Toshiba logo.
I have disabled secure boot in the bios (I did so it would install correctly) but still no joy. All other settings are default (boot order etc).
Have I done something wrong? Sorry if its obvious!
