I have an ASUS PC computer that got totally shut down improperly. It was in the middle of re-starting when it got shut down. I turned it on again, and it gave me instructions to change the CSM Parameters. I did that and restarted the computer again. The computer now says, "reboot and select proper boot device. Or insert boot media in selected boot device and press a key". Does this mean I changed the CSM Parameters correctly? What should I do now? I'm not sure what a boot device is. Will it destroy the information on my computer? Please help! I'm using a laptop but I miss my PC!

You just need to go into boot devices, might be called something different, such as CSM, then make sure it sees your hdd as the first boot device.

CSM is Asus's Compatibility Support Module and is located typically in the danced section of the boot menu on the uefi boards. As Mouse mentioned, go into there and make sure the harddrive is the first boot device.

How will know which one is my hard drive? I did change the CSM Parameters, and got the "reboot and select proper boot device [...] and press a key" upon restarting. Does that mean I changed it to my hard drive correctly and just need my boot device?
I've been told that I just need to insert the CD that came with my computer to install Windows 8 and re-install.

Your "Boot device" is your hard drive. Select your hard drive in the bios and it should correct the problem.

This is happening to me too. Everyone keeps giving the same answer, but not how to do it. I cant get past the screen that says reboot and select proper boot device. It won't let me do anything.

When starting the computer press f2, use the arrow keys to go to boot and then use your enter key to select hard drive as the first thing to boot.im having the same issue I know how to do that but it did not fix my problem I still get the same results but perhaps it will help your computer .

Unplug the computer, take battery out. Hold power button for 35 seconds. Then hold f2. This will take u to an utility screen, then go to the right until u see and option for default settings. Then save and restart. Thank me later. Glad I can finally give back to the cyber world where I get so much help from
