How to Fix Windows drive missing from Startup Disk

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Boot with -v keepsyms=1 debug=0x100 to identify the exact kernel panic.
  2. Validate your config.plist using ocvalidate.
  3. Ensure your EFI matches the Dortania guide specifications for your CPU generation.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

Hi all,

I have a working 11.2 install using OC 0.6.6, with Windows 10 and Mac OS on seperate drives. Multiboot works fine through the OpenCore picker, however I want to be able to use the Startup Disk utility like on a real Mac. The windows drive does not show in the Startup Disk, so currently I can't boot from Mac to Windows without using the OC picker. The dortania guide only covers installing drivers on Windows.

What should I do to make the drive visible in Startup Disk?

Observations:

  1. The windows drive is not mounted in MacOS by default
  2. I have never ran the BootCamp utility in Mac OS
  3. I have configured LauncherOption

Thanks in advance!
