Cannot start my macbook properly.
I need to explain in detail so you can help me out!
I am using a Mac-book Pro 11,1 mid 2014, retina display, Running on mac OS Sierra. I switched to windows operating system using the boot-camp software for like 2 years, and due to some corrupt files, i decided to reset my mac while still using the windows operating system without switching back to mac OS and after resetting it, i could't find the boot-camp software again, so i had to download it and chose to "RESTART WITH OS X" provided in the bootcamp list option, which it did, but i forgot my password while trying to login to my mac on my Default operating system. I then decided to reset again while on my default operating system which was Sierra, using the "POWER BTN + ALT/OPTION + R", i then erased the Macintosh hardrive and it needed to install a fresh copy of the Sierra again, i then started the download, but it kind of hooked and i decided to power of the system, but when i roboot it, it says "NO BOOTABLE DEVICE, INSERT BOOT DISK". Ever since it has refused to either boot properly or go anywhere else, i don't know what to do.
