BootCamp: "No boot device is available, press Enter to continue."

I'm running Parallels 12.2.0 on macOS Sierra 10.12.4. I have an existing Windows 10 BootCamp partition on my Mac that I'd like to use with Parallels. However, when launching the VM that I created with it, I get a black screen with the message "No boot device is available, press Enter to continue" along with a bunch of other text from it trying to boot from SATA drive 1, SATA optical drive 2, and from networking.

The BootCamp partition works fine when I'm not trying to access it from Parallels. I've never gotten this message outside of Parallels.

I've gone through the steps listed on these pages, but they've had no effect:

(The second link is essentially the same error message I'm getting)

Please advise!

 

Please, check that EFI is enabled for BootCamp virtual machine: go to VM configuration -> Hardware -> Boot Order -> Advanced Settings -> Use EFI Boot.

 

EFI was disabled. I've enabled it and retried, and I get this screen:



Pressing ESC or any other keys merely enters text into the command line.

 

Hi @EricP5 , please remove the existing boot camp from Parallels Control Centre and then please perform Sfc scan and check disk on the native boot camp and then try to run the Boot camp using Parallels Wizard and let us know if that works.
