Hi Omkar,
It seems that there is an issue with the BitLocker preparation tool while running Azure Disk Encryption. The error message suggests that you may need to manually prepare your drive for BitLocker. Here are a few things you can try to resolve the issue:
- Check if the VM meets the prerequisites for Azure Disk Encryption. Ensure that the VM is running a supported operating system and is in a supported region. You can find the list of supported VMs and operating systems in the Azure documentation.
- Check if the VM has the latest updates installed. Ensure that the VM has the latest updates installed for the operating system and the Azure Disk Encryption extension.
- Check if the VM has the required permissions. Ensure that the VM has the required permissions to access the Key Vault and the storage account.
- Try manually preparing the drive for BitLocker. You can follow the steps mentioned in the Azure documentation to manually prepare the drive for BitLocker.
If none of the above steps work, you can try contacting Microsoft support for further assistance.
