Unfortunately I don't have the answer myself, but I've had a little look (googled for you): http://www.linuxquestions.org/quest...-select-boot-options-grub-boot-loader-303149/ It sort of confirms what I inititally thought, so worth checking the legacy support for USB again. That also suggests removing the internal card reader (if fitted), but I faill to see how that should make any credible difference unless it was causing a conflict. The fact BIOS recognises it, and so does the actual installation shows its OK. If its working in BIOS it should be working in Grub though. Its a odd one, and hard to find information online for your exact problem.
still experimenting... unfortunately i have to have a hardwired keyboard connected so i can choose in grub...i dont get it but am checking out what u googled for me.. ty again leeky
so.. ive been busy... but besides that.. i loaded ubuntu today and i did updates ..after it all ran and rebooted grub loaded and with my secondary keyboard i pressed the right arrow.. this somehow loaded a command line and i typed sudo grub... it told me there was no grub menu or something and asked if i wanted to download it...(y/n=y) then after it did this.. i rebooted the system and loaded grub using the wireless keyboard... everything is fine now.. i can access everything with no problem now...
