Using one TB windows disk to boot multiple macs

[austinpike]

A buddy of mine wants to be able to boot a Macbook pro and and iMac with one Windows 7 installation on an external Thunderbolt drive.

I've installed Windows 8 to an external TB drive for use with a new Mac Pro, and that works fine. My question is, how upset is Windows going to be with regards to licensing/drivers when swapped between two systems?

My assumption is isn't a great idea, but maybe the hardware and drivers are similar enough that it could work?

Activation won't allow this, and the hardware isn't identical, so there will be problems.

You will surely need other methods to run Windows like this.
From Windows 8, Microsoft introduces a new "Windows to go" mode, allowing users to install Windows on supported USB3.0 hard drive, and carry this installation anywhere within a whole organisation. Unfortunately, this feature is limited to Windows 8/8.1/10 enterprise SKU.
