Cannot boot - just displays L followed by 7's
I have a Dell computer, and put in a new hard drive to put Mandrake Linux on. I wanted to be able to either boot Linux or Windows from the computer. But something horrible must have happened! I installed Linux on the new hard drive, but when I boot it up I just get a bunch of 7s on the screen! I have NO idea how to boot Linu or Windows? How do I get back into windows? And also, is the data on my main hard drive (the windows one) still salvagable?
Thank you so much.
