+## Troubleshooting
+
+When using the boot disk, you might experience a situation where you see a black screen with a white
+circle and diagonal line running through it. This means macOS lost or can't find the boot disk for
+some reason. To correct this, shut down and boot up the system again while holding down the
+`OPTION+COMMAND+R+P` keys simultaneously. You might want to wait for the system boot sound to happen
+a few times before releasing the keys. This will clear the system NVRAM/PRAM. At this point you can
+shut down and restart the system following the boot disk instructions (the boot disk will be
+recognized now).
