I tried installing openSUSE on a 40GB windows 10 system (15GB used) and it decided to wipe windows completely, without additional notifications apart from the partitioning summary screen that says "remove /dev/sda1" ;-)
That sounds like a bug worth being reported.
What's the bug I should report?
Having wiped the foreign partition without a big red alert.
I think it is just working as designed.
Someone decided on BTRFS as default. BTRFS can not reasonably be used on less than 40GB. (Personally, I would never ever put BTRFS on anything smaller than 100GB but that's a different story). The installer encounters a device with 40GB "disk size", fully occupied with windows10. The installer's preselected default is BTRFS. So there's no solution other than "wipe windows".
There are alternatives:
- fall back to a different file system for this situation, or an otherwise modified proposal (e.g. just shrinking windows as you mentioned) - pop up a window saying that the installation can't be done on the available free space, and propose to wipe windows after user confirmation
Both would be better than the behavior you reported, IMO.
