I shut down my computer for a week, while on Vacation, and now when I boot up, I get the following message: Reboot and select proper Boot device Or Insert Boot Media in selected Boot device and press a key I have an Asus Motherboard with Intel i7 Core processor and the system is running Windows 7 o/s. I can reboot the system and get into the BIOS and see that the boot priority is set-up correctly. Also, I can see in the BIOS that the boot drive is present. When I physically disconnect the boot drive, it is missing in the BIOS. That tells me that the BIOS can properly see the Boot drive. I don’t have a floppy drive and there is no disc in the CD/DVD ROM when I reboot. I have tried to reboot with the Windows installation disc, but when I do so, it tries to re-install the o/s and I don’t want that.
