Critical BitLocker Boot Failure After Deploying Windows 11 24H2 Master Image

Question

I need to report a critical issue encountered while deploying a Windows 11 24H2 master image with BitLocker encryption. This problem is causing significant operational delays during our annual laptop replacement cycle.

Issue Summary

After deploying a sysprepped Windows 11 24H2 master image and enabling BitLocker, affected devices enter an Automatic Repair loop upon restart. This issue does not occur with the previous Windows 11 23H2 image or fresh 24H2 installations on individual devices.

Steps to Reproduce

1. Master Image Creation Process:
   • Fresh install Windows 11 24H2 using the official Microsoft ISO.
   • Install mandatory drivers and Office 365.
   • Sysprep: sysprep /generalize /OOBE /shutdown.
   • Capture the image using Clonezilla/Acronis True Image.
   • Deploy the image via Windows PE boot.
   • Create a local user, join to Active Directory, and enable BitLocker encryption.
2. Result:
   • After BitLocker encryption and reboot, devices crash and enter an Automatic Repair loop.

Troubleshooting Attempts

• Ran sfc /scannow (no integrity violations found).
• Repaired the EFI boot loader (no resolution).
• Confirmed the issue is isolated to 24H2 master images (23H2 and fresh 24H2 installs work normally).

Impact

This blocks deployment for 20–40 laptops, forcing time-consuming manual installations. For enterprise IT operations, this is unsustainable.

Could you confirm if this is a known issue with Windows 11 24H2 sysprepped images and BitLocker?
