Question: “No bootable device — insert boot disk and press any key”

I downloaded a Windows 10 ISO installation file and used BootCamp and a 8GB USB stick to download it. When my computer restarted after the installation was complete, this message can up and I can’t do anything about it (tried holding option etc. already).

Can anyone help me with this?!

Also, the first time I did exactly that (Install option checked, created partition for Windows 10, and tried to install it). When the computer restarted, it came up with the “boot disk” message. How will doing this again help?

You are in Internet Recovery, because the Mac is unable to boot from the internal disk.

The first two BCA options allow creation of the USB installer, which needs to be done only once. The Install Option can be independently checked, which allows the same installer to be re-used, if you choose to remove the partition, and create a larger or smaller partition.
