So I downloaded instantcake and Burned it to cd but I cant figure out how to make my computerboot from cd. My problem is that I ordered 2 tivo's from e-bay but neither of them came with a hard drive. Can someone help me im about to throw these things out the window. Ive got 2 phillips PTV300's Series 1 and my computer is a Dell Dimension 4100. and I need the image for my tivo hdr312. Thank you
