Back in the days when people still had floppies and cd drives in their computers, yeah things were dead-simple. You pop in a disk, format the hard drive, and walk away while the process completes. I miss that. The machines I've worked on in probably the last decade, it seems like I have to fight against the hardware every time I want to wipe the system or replace a failed drive. The last set of servers I got, I couldn't figure out why the linux image (with full EFI settings) refused to even boot up properly. Turns out Dell had made these machines so you could easily boot a Windows installer from any of the external USB ports, but to install linux you had to use a hidden internal USB port. Once I found out about that then yeah the installation went as planned, but this is the kind of BS I'm referring to about manufacturers trying to prevent users from getting rid of Windows.
