Quote ="Enicomb"You did buy one with an OS installed? If so you need to configure the boot devices in the BIOS on boot. It depends on the computer but it'll be either f2, f12, f10, f8, esc or del and set the boot device to be the hard drive. Even more unlikely is that the hard drive is unplugged (you'd need to open it up and check it has both power and data cable plugged in; again I doubt that's your issue)
Most manufacturers set this up correctly though, so it sounds more like you've bought a computer without an OS, in which case you'll need to get hold of one and install it. Windows is over £100 but you could get ubuntu which is free.'"
