I recently purchased a new Wireless mouse and keyboard. I did all the steps for setting it up but when I turned the computer back on, then Windows started to give me error messages to send an error report or something. So, I restarted my computer and when it started to boot then I got this error message that stated "Reboot and Select proper Boot device or insert Boot Media in selected Boot device and press any key." I went into the Bios and checked that the hard drive is still detected, so what could be the problem here? Any help would be appreciated.
