My tower pc is giving me the "Reboot and select proper boot device" message. I know that, failing a serious HD coronary, it's a case of restoring the path to the HD, but I can't find the list of boot options in my boot menu/BIOS screens
My question isn't what to do next (it's going to the shop) but: as I haven't been starting it up with a disc in the tray, or a USB device plugged in, could this problem have been caused by booting up with the CD tray open? I've done this a number of times lately and I can't see why it would affect startup.... but it's the only thing I've been doing 'wrong'
