Expanding the encrypted boot volume of a Windows instance in Amazon Web Services (AWS)

To expand an encrypted Windows boot volume:

1. Identify your Windows instance in SecureCloud and AWS web console and note the instance ID. In the sample below, the instance ID is i-338e3fc4.

   

2. On the AWS Console, click the Description tab.
3. Look for Block Devices and note down the volume ID or EBS ID of the /dev/sda1 device. Also take note of the zone details where your instance runs:
   • Root device (e.g. /dev/sda1)
   • Block device (e.g. /dev/sda1)
   • Zone (e.g. eu-west-1b)

   

4. On the Amazon Elastic Computer Cloud (EC2) console go to ELASTIC BLOCK STORE > Volumes.
5. Create a snapshot of the volume:
   1. Find the volume ID noted in Step 3.
   2. Right-click this volume ID and select Create Snapshot.
   3. Name the snapshot and take note of its name.

   

    

   Note: Creating a snapshot may take some time depending on the volume size.
6. Create a volume:
   1. Go to ELASTIC BLOCK STORE and select Snapshots.
   2. Right-click the newly created snapshot and select Create Volume from Snapshot.
   3. Enter the new size.

   

    

   Note: The availability zone must be the same as the instance you noted in Step 3.
7. On the Volumes page, right-click the newly created volume from the snapshot and select Attach Volume. Attach the volume to the instance using /dev/sda1 as a mount point.

   

8. Power on the instance. The SecureCloud management console will update the disk size and will show “Encrypting” status.

   

9. Connect to the instance using Remote Desktop. Open the Run window and enter “diskmgmt.msc”.

   

   

10. Right-click the unallocated space and select Extend Volume. This will expand the disk size.
