Occasionally when you are deploying a machine using system center, you might be presented with an 0x80070070 error just after you’ve chosen your task sequence, but before it starts in full..
In order for this to work, you must have command support turned on in your boot images.
When the error is presented, press F8 to bring up a command prompt and enter the following set of commands:
select disk 0
Then restart the deployment. This should allow you to deploy the machine without issues.
