I didn’t find the entire list of challenges I faced in any single web site, so I have decided to write my discoveries down here, in an ‘integrated’ manner. Each of these issues represents some hours of repeated head-banging attempts to get past it that I hope to save you, dear reader, from repeating. I had to get past multiple ‘I should give up because there is no apparent way around this, and the error message gives me no help at all’ situations, spread across what became an entire weekend of trial-and-effort and repeated fruitless attempts at things that took ages, punctuated with just enough ‘ah hah’ moments and clues found via Google to keep me doing it…! My intention was install Windows 10 using Bootcamp, with an arbitrary 50/50 split of the 1.1Tb Fusion Drive.Īt the start of the fateful weekend concerned, I recall thinking ‘how hard can this be?’ because I’d installed Windows using Bootcamp on my current-generation MacBook Pro (with a big SSD) with zero issues at all. This is a small SSD blended with a 1Tb Hard Drive. The Fusion Drive was designed to leverage fast-but-expensive SSD’s with slow-but-cheap hard drives, before SSD’s got so cheap that the hard drive became almost irrelevant. The iMac has a then-fastest-around 2.9Ghz CPU and features the (then) latest and greatest storage innovation, the ‘Fusion Drive’. I wanted to set up this machine to run some specific Windows software for which it was well suited, and that let me make good use of an otherwise idle machine. I recently managed to install a current Windows 10 distribution onto an older iMac that I had in storage. “The experienced driver”, he says, “will usually know what’s wrong.” Rather, if the driver makes any mistake, a giant “?” lights up in the center of the dashboard. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the numerous idiot lights which plague the modern driver.

Ken Thompson has an automobile which he helped design.
