Having purchased a Segate GoFlex Desktop Thunderbolt Adapter made me wonder if it's possible to install a Bootcamp-Partition on an external Drive. Well it works; sort of.
- Launch Boot Camp Assistant.
- Select the local Drive for installation (not the external Drive) it will take about 20 GB of disk space.
- Boot Camp Assistant will now repartition your local drive.
- Wait a while for Boot Camp Assistant to finish preparing the drive.
- When the Windows 7 Installer comes up simply choose the external drive as target, not the local one.
- Proceed with the installation.
When booting your Mac (holding the Option key) you'll now see that there is a local Windows 7 boot volume.
Unfortunately, you will have wasted 20 GB creating a partition on your main drive.
[kirkmc adds: I haven't tested this. I don't know if Disk Utility can delete that partition; live partitioning is possible, but in some cases certain partitions can't be deleted.]
