Connect to Serial Console and Use PowerShell:
- First, ensure that the Serial Console is enabled for your VM. If not, follow the instructions to enable it¹.
- Connect to the Serial Console and open a CMD instance.
- Check the boot configuration data:
bcdedit /enum
If the VM is configured to boot into Safe Mode, you'll see an extra flag under the Windows Boot Loader section called
safeboot
. The possible values areMinimal
orNetwork
. RDP won't start in either of these modes.- To make the VM boot into normal mode, delete the
safeboot
flag:
bcdedit /deletevalue {current} safeboot
-
Verify that the
safeboot
flag is removed:
bcdedit /enum
Restart the VM and check if the issue is resolved.
-
Repair the VM Offline (if needed):
- Attach the OS disk to a recovery VM.
- Start a Remote Desktop connection to the recovery VM.
- Ensure the disk is flagged as Online in the Disk Management console.
- Note the drive letter assigned to the attached OS disk.
- Optionally, enable dump logs and Serial Console for further troubleshooting².
- Now you can perform the same steps as above to remove the
safeboot
flag and reboot the VM.
Remember to take a snapshot of the OS disk before making any changes as a backup. These steps should help your Azure VM boot normally without the CrowdStrike-induced BSoD. 😊👍¹³
