Paid for an upgrade to Parallels 11 today, and proceeded to try and upgrade my Win 7 setup to a Win 10 setup. It's been a waste of a whole day pretty much. Right now when trying to upgrade, it says my drive is Locked. Upon digging further, it seems like my VM just disappears during the setup, and the upgrade thinks the setup program is running off of a CD, which it's not. (I have a 2013+ rMBP w/o a CD-rom drive) So what now? I can't repair anything, because it's not recognizing a drive to repair to. The system won't update, only revert... it's annoying.
