You probably should not "hold" the F2 key... you only "tap it" once or twice when you see that screen. Holding down a key often gives a keyboard error. I really do want you to be able to access BIOS reliably... we may need to get in and out of there a few times (if it is working properly).
About the grub> commands... I'm curious where or how you got the commands you used up above in post #11. They could be close to being correct if you got the information from grub using the ls command. But if you just copied and pasted from a website somewhere then they could be all wrong too. Did you use ls at your grub> prompt?
I just got them from a forum.... No I did not use ls, didn't know. I will put that hard drive back in later and try again so any other info I can try at that time will be helpful.... wonder why the stupid website said to hold it down lol and when do I tap it?
