When installing Windows 10, I would recommend you do not use VirtualBox. This means you would need to restart the installation process. Since the first partition on the external drive starts at sector 2, the drive does not have the space to convert from a MBR partition table scheme to a GUID partition table (GPT) scheme. The 2017 model Macs can only EFI boot Windows.

Would this entail restarting the entire installation process? Any information would be greatly appreciated :) My guess is that I need an EFI partition for the newer mac to recognize my drive. Here is some disk information that may help: $ diskutil listġ: Windows_NTFS BOOTCAMP 353.1 GB disk2s1ĭisk: /dev/disk2 geometry: 124519/255/63 Using System Preferences startup disk leads to this error: The bless tool was unable to set the current boot disk. However, the Startup Manager does not recognize my external drive and only display my internal drive.

This setup has worked for me on my old MBP (I can hold option to boot into windows). I have a 1TB SSD that has a partition with a Windows 10 installation (I followed this tutorial: ) and another MacOS Journaled partition that I use for general file storage. I just got a new Macbook Pro, I was previously using an MBP (13-inch, Mid 2012) running Mojave.
