Two stupid question: 1. Do I run sdc-boot first and then usb-boot? Or do I only need to run usb-boot? 2. Do I need to run sdc/usb-boot on my rapberry Pi or on a seperate computer? If so, my computer does not have an SD card slot, so it recognizes my SD card as /dev/sdX and not as /dev/mmcblk0.

I already have a mini-ITX computer working fine as my "TV-computer" for the not so intensive game Stepmania, better known as Dance Dance Revolution. But I thought "You know what? Maybe I can go smaller." Raspberry Pi 4 smaller. But in my experience with raspberry Pi 3s and SD cards, they tend to die...
