I have a IBM thinkpad and can't seem to get far on startup! When I turn on laptop it goes to a screen that shows a picture of a drive and a disk. At the bottom is a bar with the F1 to F12 keys. There are two arrows pointing (blinking) at the F1 key. There is also a arrow moving to show to enter a disk. What does this mean? Does this mean I have no operating system? Is there something missing? Any info? Please help!
