The last attempt to restart the system from it's previous location failed. Attempt to restart again? [And two options appear, the top one is selected, and my keyboard WILL NOT allow me to choose the second, I hit the down arrow, and nothing happens. The options are]:
Delete restoration data and proceed to system boot menu. [This is highlighted]
Continue with system restart.
At this screen my keyboard will not work, but if I press a button such as F10 while waiting for the screen to load, my keyboard works through-out the menus.
