In the mid-2000s I once tried installing Windows XP to a 16GB eMMC drive that was in a PCI slot adapter on my main PC. It did install successfully, just as it would on a normal hard drive. It did boot. The only problem (besides it being only 16GB) is it took forever. The PCI slot transfer speeds were slow. The eMMC card itself was slow. I can't recommend doing it, but it does work.
