Once you do get the upgrade installed, you can use Magical Jellybean's KeyFinder to get your shiny new Windows 10 key, then if you want, do a clean install that way. simply go to 'Reboot and install updates' and it will complete the setup that way.

Specifically it will die when it's trying to reboot and say 'Something Happened' and that it failed. you can't btw) the update will fail on the new rMB 2015 because of the new SSD. if you don't have a purchased Windows 10 key and are instead getting a free update to it from Win7 or Win8x (I'm guessing not bc of wanting to boot to an iso, but just in case you think you can upgrade that way. Called back a second time (waited 2 hours on hold *again* and got the same answers.)Īnother thing. I literally (as in the real definition of it) spent over six hours today on the phone arguing with Microsoft that I needed a key and had valid Win8.1 keys but they said no, you *have* to do an upgrade. MAKE SURE you have a Windows 10 key *FIRST*. For instance, I used the Windows 10 Media Creator to make an ISO that had 32-bit and 64-bit versions on one disk and it didn't get recognized. You have to download the specific Windows 10 64-bit ISO from Microsoft.



if you downloaded the ISO file below than this, you will get this error.
