I have the same problem as this:
My laptop is Lenovo ideapad P400
I tried using the rEFInd USB but it is not booting.
I can't access the bios, I tried all of F button.
how can I resolve the problem? Trying to install a new version of windows with USB will work? The lapton is new. less than one month. If I go back to best buy where I bought it will they restore the original version of win 8 for free? I don't care about the data inside.
