I can't answer this because the most likely location for the answer [1] is locked behind a beta program access or something, but where do they plan on taking the reserved storage from? I assume they're not going to try to repartition the drive? It sounds like they're just using filesystem features to carve it out of an existing partition, but I'd like to be sure. My laptop is currently dual-boot, but if Microsoft starts blindly mucking with partition tables it's gonna go single-boot Linux right quick. (I <i>expect</i> it's not that, but I'd like to be sure.)<p>As long as they're staying out of the partition table, this sounds like a good idea to me, honestly.<p>[1]: <a href="https://insider.windows.com/en-us/ih/?contentid=2762bf7a-bef0-4835-8e4c-04ae8e3ed299&contenttype=quest" rel="nofollow">https://insider.windows.com/en-us/ih/?contentid=2762bf7a-bef...</a>
