\n1. Disable Secure Boot<\/strong><\/p>\n\n- Access the system\u2019s BIOS\/Firmware settings.<\/li>\n
- Locate the\u00a0Secure Boot<\/strong>\u00a0option and set it to\u00a0Disabled<\/strong>.<\/li>\n
- Save the changes and reboot the device.<\/li>\n<\/ul>\n
2. Disable Virtualization Technologies (if issue persists)<\/strong><\/p>\n\n- Re-enter BIOS\/Firmware settings.<\/li>\n
- Disable all virtualization options, including:\n
\n- Intel VT-d (VTD)<\/strong><\/li>\n
- Intel VT-x (VTX)<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
Note: This action may prompt for the BitLocker recovery key, so please ensure the key is available.<\/em><\/p>\n3. Check Microsoft Defender System Guard Firmware Protection Status<\/strong>
You can verify this in one of two ways:<\/p>\n\n- \nRegistry Method<\/strong><\/p>\n
\n- Open Registry Editor (regedit).<\/li>\n
- Navigate to: HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\DeviceGuard\\Scenarios\\SystemGuard<\/li>\n
- Check the\u00a0Enabled\u00a0DWORD value:\n
\n- 1\u00a0\u2192 Firmware protection is enabled<\/li>\n
- 0\u00a0or missing \u2192 Firmware protection is disabled or not configured<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n
- \nGUI Method (if available)<\/strong><\/p>\n
\n- Open\u00a0Windows Security > Device Security<\/strong>, and look under\u00a0Core Isolation<\/strong>\u00a0or\u00a0Firmware Protection<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
4. Disable Firmware Protection via Group Policy (if restricted by policy)<\/strong>
If firmware protection settings are hidden due to Group Policy, follow these steps:<\/p>\n\n- \nUsing Group Policy Editor<\/strong><\/p>\n
\n- Open\u00a0gpedit.msc.<\/li>\n
- Navigate to: Computer Configuration > Administrative Templates > System > Device Guard > Turn On Virtualization Based Security<\/li>\n
- Under\u00a0Secure Launch Configuration<\/strong>, set the option to\u00a0Disabled<\/strong>.<\/li>\n<\/ul>\n<\/li>\n
- Or via Registry Editor<\/strong><\/li>\n
- [HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\DeviceGuard\\Scenarios\\SystemGuard]<\/li>\n
- \"Enabled\"=dword:00000000<\/li>\n<\/ul>\n
