Windows 10: pc cant boot and displays "reboot and select proper boot device" error after sudden power...

i was just using my computer normally until the PC shut off and turned back on. i was met with the black screen with the message on it. I've tried changing the boot order windows boot manager was already 1st one, resetting bios by removing the cmos battery, and trying to boot windows from a 8gb bootable usb that I made from a guide, windows 10 iso and the macos terminal. any help is appreciated. i have a asrock z370 mb if that helps

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?

"Reboot and Select proper boot device or insert boot media in selected boot device"

Hi, I recently built a new PC with a 1TB Samsung 860 EVO SSD. I'm installing Windows 10 via USB and I've made the USB top priority in the boot list. However, when I exit BIOS, It gives me an error saying "Reboot and Select proper boot device or insert
boot media in selected boot device and press a." Is their a solution to this?
