Partition scheme format popup doesn't come up.

I'm following this guide on install Windows on my Samsung T1 SSD Portable

However I cannot do step 7 as when i select the destination disk there is no popup window like shown below in the guide.

This window will only pop up when the destination device is a USB stick. You had to manually format the destination device if it is an external hard drive. Here is the guide:

This is an artificial limitation. Please file bug report. If not artificial, then nonsensical.
