I caught my 2 1/2 year old granddaughter who wanted to see pictures booting up my PC and pushing buttons on the keyboard. Whatever she did caused it to reboot to the advanced bios screen. How can I get back to a normal boot without causing any damage? Can I access the hard drive to copy files another way so I do not loose them? Any help would be greatly appreciated.

Thanks, just one question, does the primary drive have to have the same OS?
