What am I planning to do with this PC?
Well Microsoft, I would like to start by installing Windows 10 on a SINGLE hard drive, without first having to physically disconnect my other drives to stop it from putting the system reserved partition somewhere other than the drive I want it to be on. Is that one of the options?
Or perhaps "I would like to have some damned control over how many partitions your OS creates, and I would like it to leave all my other partitions the hell alone during updates"? Any of that included in the list of questions about how I would like to use my PC?
