Why won't my mac boot?

crwdns2934249:0crwdne2934249:0:

Hello everyone,

A few days ago I tried using bootcamp on OS Sierra for installing windows 10.

Unfortunately it failed and now whenever I switch on the laptop, I get a black screen saying "No bootable device - insert boot disk and press any key".

I have tried using all the keyboard shortcuts including: using 'option/alt key', 'command+R', 'command+alt+P+R'.

The keyboard doesn't function as pressing the caps lock button does not turn the light on.

Nothing seems to work and now I am stuck with this problem. If there is anyone who can kindly assist me with this I would highly appreciate it.

Thanking in advance.
