Windows unable to bootup after updating to Mojave 10.14.6

After choosing the windows partition, you will see the windows logo as usual, but it will shutdown automatically after 3 seconds, could anyone help to solve this problem? (Tried PVRAM, System Control reset, whole mac disk partition fix, All useless!).

P.S. (Could access the Bootcamp Partition AS USUAL IN Mojave OS)

Model : Macbook Pro (2014 June)

Update Date : 25-07-2019 17:00 (GMT +8)

Problem Solved following these steps in command prompt:

  1. brew install gptfdisk
  2. sudo gdisk /dev/disk0
  3. x --> n --> w (Create a new protective MBR --> write to existing disk and exit)

@Loner T Thanks for solving that, may I wish to know what is the behind mechanism of all these functions? :)

For W7 and older Windows versions, we need a Hybrid MBR (http://www.rodsbooks.com/gdisk/hybrid.html). This allows the Macs to mimic a PC and also support a BIOS emulation called CSM-BIOS.


For W8.1/W10, you can use BIOS or EFI, on late 2013-2014 Macs. On your specific model, BIOS is the default. If you select EFI, you also need to remove MBR to allow a GPT layout to be exposed for EFI installation to work. By removing the Hybrid MBR and the underlying GPT disk using the commands you have mentioned, you were successful.


Can you ru msinfo32 in Windows post the value of BIOS Mode? Does your Audio work properly?
