I want to add a caveat to this. I really don’t like relying on OS type as a defining factor. That said, 1.3.0 still relies on OS type to determine if it’s a valid resizable OS (Windows XP,Vista,7,8,8.1,10) and (Linux, Chromium OS). It also relies on the os type to determine the “fixed_size_partitions”. Of course the fixed_size_partitions file can be edited after the upload, but I am still under the impression we should really use it from the GUI. I will work on it, but for now I’m glad this is working.
