"No bootable device -- insert boot disk and press any key"

I had deleted my Bootcamp partition before I reset my startup disk to my the one for Mac OS. On computer start up, I get the "No bootable device -- insert boot disk and press any key" message. I have tried suggests like hold down the option key during start up, and hold down command-R during start up. The system ignores that I have the buttons down and presents me with the above message every time.

I was actually in the process of trying to clean up the computer when this happened. At this point, it would be great if I could just erase the disk and reinstall Mac OS from scratch. I tried using the DVD that came with my Mac, but the DVD in the drive is ignored and I get the above message. I know the DVD drive works since it is able to read a Windows 7 DVD.

How can I do a clean installation of Mac OS when the hard-drive is in this state?

Thanks in advance!!!!

Pressing alt-command-p-r until I heard the third chime worked for me. I had to connect a usb keyboard to do this though. The keyboard on my macbook would not work, I only got this to work after connecting a usb keyboard.

I had the same issue, and it happened just after I try (and failed) to install a Paragon disk as my disk for the Time Machine. I also had the "PARAGON NTFS FOR MAC" installed.

Thanks a lot. I suddenly found my macbook is saying that there is no bootable device. Your suggestion worked and I got back my machine without any data misplacement. 🙂✅

Thanks this worked. Just don't enter the wifi password like I did and click on McIntosh HD As it did not work. Just do as what was mentioned above.
