> You don't seriously think that was anything but a consequence of your specific setup, right? Dual booting with Windows 8.1 and Linux is most certainly possible.

Yet is is. It is a consequence of the fact that windows overwrites things like the master boot record that live outside of it's partition on a hard drive without asking the user first.

Yes dual booting is possible. But as always installing windows second makes everything else unbootable (until fixed).
