In my years of building PCs and writing about consumer tech, I’ve built and fixed several PCs for friends and family. I’ve embraced the dreaded resident tech support role in my circles, and as a result, my life shares similarities with corporate system administrators now. I’ve seen that worried helplessness too many times when PCs won’t boot and users are left helpless. So now, I show up with a single fix-all bootable USB drive packed full of powerful ISOs and diagnostic and recovery tools. This digital Swiss Army knife easily puts a Windows installation stick to shame.
