Taking precautions
You might need Windows later so let’s make sure it’s not going to get upset.
Dual-booting is great. You can have a Windows install for proprietary applications (be it overpriced office suites or convoluted CAD packages) and those AAA games that don’t quite work with Proton. And when you’re done with those, you’re just a three-fingered salute away from Linux, where you can do everything else.
But what happens when it goes wrong? Well a quick DuckDuckGo search gives one an idea: “Windows updated and broke Grub”, “Windows corrupted my exotic Linux partitions”, “Windows boot manager upsets my chihuahua”. Okay, one of those may not be real, but dual-booting has undoubtedly caused problems in the past. We endeavour to make the experience problemfree in the present.
