    I have Windows 8.1 installed through Boot Camp currently on my Mac. Within Win8.1, I am prompted to upgrade to Win10, which I would like to do, but only after this upgrade process is 100% supported with bugs having been resolved.

    Are there any reports of problems initiating an upgrade from Win8.1 to Win10 from within the Win8.1 partition, and then having it supported by Boot Camp?

    Info for context, no need to read:

    The reason I'm so anal about making sure this is a validated, effective, problem-free path to updating, is because it was an incredibly arduous ordeal to get my Mac configured as it is with dual data drives and boot camp. It's a 2011 17" MacBook Pro. I had already replaced the internal Superdrive with the included HDD and then put an SSD in the primary data drive slot when I decided I wanted to install Windows on the HDD (which was my secondary drive). It turns out that on this model of Mac (as well as some others that came with Superdrives), there is a nonsense requirement to install Windows from a DVD inside an internal Superdrive. Even though Macs of the same generation that came without superdrives can install Boot Camp from external superdrives, and even though newer macs support installing Windows from USBs. I tried everything including using an external superdrive, using an external generic DVD drive, and using USBs, but true to Apple's documentation the only thing that would work is installing from an internally-installed superdrive. So I had to revert my entire hardware setup, moving the HDD back into the primary drive slot, putting the superdrive back in, re-installing Mac OS on the HDD so that I could run Boot Camp utilities, just to get Windows installed on that drive, so that I could put all the hardware back in my preferred places.

    Needless to say I'd rather stick with Win8.1 until I die than do this again, so I don't want to upgrade to Win10 unless its known to work 100% of the time.

    I fully understand your concerns. I've seen many members go thru the same thing as you did in order to install Windows on a machine that had its optical drive replaced with another hard drive. Apple Boot Camp guidelines follow along with Microsoft's anti-piracy practices which prohibit what you were trying to do since it assumes the "other" drive is external.

    I can't answer your question about upgrading 8.1 to Windows 10 on that drive. There is a chance it will do the same thing as before and prohibit the upgrade installation. However, it wouldn't hurt to try anyway. The worst that can happen is that it will refuse to upgrade and you'll still have Windows 8.1. And since Windows 10 is a free upgrade from 8.1 all you'll suffer is some frustration. :(

    I've been using Win 10 in both Boot Camp and Parallels VMs for a couple of months, with few issues after the initial growing pains (driver updates, etc.). There's one VM we have on the Insider Track, and it's updated to the relatively update that's going public next week - it's smoother, far less buggy, and just works. I came over from 8.1. Some of our installs were clean, the rest were upgrades. We use Windows for Office/CAD/Adobe CC/minor rendering - Win 10 isn't perfect, but I find it easier to use than Win 8/8.1.

    My take and advice is to wait until the Win 10 update hits the interwebs, actually, wait a day or two after that as MS's servers will be hammered into submission for a bit.
