Sorry for the noob question.. I have a new Raspberry Pi 4 and a Windows 10 PC. My original plan was to flash the image to a USB, boot using the USB then format the SD card with a primary ext4 or ZFS partition and install the OS there, then boot using the SD card.
However, I see that v20.x beta does not support USB booting yet so what are my options here? Do I create a small 5gb partition on the SD card to boot and then format/install on the unallocated space on the SD card? If so, how would I later recapture the temp partition that I used to boot?
