Windows 10: reboot and select proper device

hello I just bought a new PC tower on the fnaf and when I launch it it says "Reboot and select proper device or insert boot media in selected boot device and press a key" the pc is an asus prime A520M-K and I really need help

:)

 

"reboot and select proper boot device" after fresh install

I understand your logic.
But that is not what is happening.
See.



It simply won't go.

On the other hand, if I take this path... brings me to W10 from where I'm posting *Smile

 

Reboot and Select Proper Boot Device...after reboot?

Hello all. Getting a little frustrated here. A couple of weeks ago we had a user come in on a Monday morning to find that her pc was displaying the classic message "Reboot and select proper boot device...". Tried popping in a windows disk and fixing the MBR, no luck. Ended up reinstalling windows and her few programs back on it. All was good after this. For about a day. She came in the next day to find the same message. So at that point we decided that more than likely the drive was bad even though oddly enough it tested out fine. It was a Corsair 60gb SSD.

Last week we swapped that Corsair with a 64gb Crucial SSD and installed Windows. We then created a backup image of that drive. All was good until Thursday when her power strip that the PC was plugged into got tripped. Start up the computer for find "Reboot and select proper boot device..." message. So, apply the backed up image to the SSD since repairing the MBR didn't work.

Now this morning she comes in and the PC is running fine. Attempts to open Microsoft Word and she gets a pop-up stating there isn't enough disk space. So, she then restarts and upon booting back up gets "Reboot and select proper boot device..."

Any ideas what is causing this? Is it something with the mobo or do I just have horrible luck and replaced the bad SSD with another bad SSD?
