I installed Mojave to a MacBook Air (2015), and used bootcamp to install Windows 10 (latest SAC) as second OS followed official Apple method of BootCamp assistant.

My problem is the only possibility to select OS is the boot + option key method:

If I select Windows, the Windows version of bootcamp show only the Windows partition as boot disk, so I cannot select/boot into MacOS. Similar as on this picture: https://i.stack.imgur.com/LZbYv.png If I set the OS here, MAC will set default OS to Windows, so without holding option key, MAC will boot into Windows in the future.

If I select MacOS, the Startup Disk show only MacOS partition, so I cannot select/boot to Windows, like on this picture: enter image description here If I set the OS here, MAC will set default OS to MacOS, so without holding option key, MAC will boot into MacOS in the future.

Is there any way to see both boot disk under MacOS and Windows too? I want something like this: enter image description here

The MacBook will placed to a remote location, so I will have no access to it at boot time, cannot hold the option key.

  • What is your question here: How can you see the disk of the other OS, or how can I preselect the OS the system boots with without pressing the Option key? – nohillside Feb 12 at 12:37
  • I changed the OP, I hope it will clear. Btw, if I see the disk of other os IN Startup Disk, it may allow to boot into it :) – M1209 Feb 13 at 6:22
