I got used to windows overwriting the MBR and could generally work around that. But the last time I tried windows/Linux dual boot, it was windows that got caught in a recovery loop after a windows update. Linux was fine. I was impressed at how thoroughly Windows had killed itself on a basic unmolested install. At that point I decided I was done with windows on bare metal unless it was the only thing running. Windows goes in the virtual sandbox or plays by itself.
