Remove USB Boot Raspberry Pi 4

[CaptainWoodrow7]

I'm new to this, so don't hate me if I'm in the wrong spot. I want to add the USB boot to my Raspberry Pi 4, but I also want to know how to remove it first. I'm just trying to figure out what to do with my Raspberry Pi, find the perfect operating system, and the best way to run it; while being able to change my mind. Also, what's a good SSD to use through USB boot if I do decide to use it?

The Raspberry Pi Imager utility can make an EEPROM recovery SD card that will restore the older bootloader, if you want to.

By default the boot sequence will be:

SD Card Boot
USB MSD Boot

So there is no requirement to keep reverting to earlier Firmware.

The booting order is controlled by a setting in a file which is held within the Boot Eeprom itself. If you wish to change the boot order, or change it back, all you need to do is obtain the configuration file, set it how you want, and tell the Pi to set its Boot Eeprom to use that.

It is intended that boot order settings will be catered for by using the 'raspi-config' app in future.

Eventually, the ability to boot from a USB MSD will be stable, then critical. Once that happens, any Pi4B that gets updated will have the ability to boot from a USB MSD. Ultimately, the EEPROM image with the feature will almost certainly be the one loaded at the factory.
