Move root partition on sata hdd(ssd)

Good day, tell me someone managed to place a" boot “partition on the microSD memory, and” / " on the hard drive via the SATA interface? (Ubuntu mate 16.04)

(I speak Russian and English)

If you use Armbian https://docs.armbian.com/User-Guide_Getting-Started/#how-to-install-to-emmc-nand-sata-usb

Does it work if I don’t have eMMC?

never mind, found it
