#Downloading the image

Download the windows image you want.

AWS vmimport supported versions: Microsoft Windows 10 (Professional, Enterprise, Education) (US English) (64-bit only)

So Home wont work.

You can download the trial Enterprise trial here: https://www.microsoft.com/en-us/evalcenter/evaluate-windows-10-enterprise

Use virtualbox to create a new virtual machine, make sure that it uses the VHD format. Install the Windows Image onto it. Install teamviewer on the virtual machine or enable remote desktop. Exit the virtual machine.

sudo apt install awscli
aws configure

http://docs.aws.amazon.com/general/latest/gr/aws-access-keys-best-practices.html During configure you can add your:

AWS access key. AWS secret access key. Default region.

If you set a default region you dont have to specify the region parameter in the following commands.

The bucketname must be unique.

aws s3 mb s3://bucketname --region eu-central-1

Move to the folder you store the virtual machine file and upload the virtual image to the s3 bucket.

cd myvmfolder
aws s3 cp myimage.vhd s3://bucketname --region eu-central-1

Create a trust policy in the file trust-policy.json

{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Effect": "Allow",
         "Principal": { "Service": "vmie.amazonaws.com" },
         "Action": "sts:AssumeRole",
         "Condition": {
            "StringEquals":{
               "sts:Externalid": "vmimport"
            }
         }
      }
   ]
}

Create a vmimport role and add vim import/export access to it.

aws iam create-role --role-name vmimport --assume-role-policy-document file://trust-policy.json

Create a file named role-policy.json replace the !!REPLACEME!! to the bucketname you are using.

{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Effect": "Allow",
         "Action": [
            "s3:ListBucket",
            "s3:GetBucketLocation"
         ],
         "Resource": [
            "arn:aws:s3:::!!REPLACEME!!"
         ]
      },
      {
         "Effect": "Allow",
         "Action": [
            "s3:GetObject"
         ],
         "Resource": [
            "arn:aws:s3:::!!REPLACEME!!/*"
         ]
      },
      {
         "Effect": "Allow",
         "Action":[
            "ec2:ModifySnapshotAttribute",
            "ec2:CopySnapshot",
            "ec2:RegisterImage",
            "ec2:Describe*"
         ],
         "Resource": "*"
      }
   ]
}

Add the policy to the vmimport role.

aws iam put-role-policy --role-name vmimport --policy-name vmimport --policy-document file://role-policy.json

Create a configuration file on your computer called containers.json. Replace bucketname and myimage.vhd with your bucket and image name.

[{ "Description": "Windows 10 Base Install", "Format": "vhd", "UserBucket": { "S3Bucket": "bucketname", "S3Key": "myimage.vhd" } }]

Start to import from S3 to Ec2.

aws ec2 import-image --description "Windows 2008 OVA" --disk-containers file://containers.json

This may take a while you can check on the status of the import.

aws ec2 describe-import-image-tasks --region eu-central-1

After the AMI is created you can navigate to the EC2 console, select the correct region.
