Help: Boot from a partition on an external hard drive

Sun Aug 12, 2018 9:35 am

Hi all.

Currently I have this setup:
RPI 3B+ running headless 24/7
Stretch on Microsd with Plex and Deluge
External 500 GB HDD via USB (automounted on boot, Download location of Deluge,Shared thru Samba) - 100% ext4

I read that we could boot Raspbian from USB HDD alone without any microsd cards. This is a better option because we have frequent power interruptions here and microsd cards have short lifespan as well.

My question is that can I resize the external HDD, make a FAT32 partition, use SD Card Copier to migrate microsd files to new FAT32 partitions, remove microsd card and finally boot from HDD without breaking my current software setup?

Thanks in advance.

using sd copier that comes with raspbian will wipe the Whole drive

if you dont mind loosing the data on the hdd then plug it in and boot from a sd-card install and use raspbians sd copier to setup the drive (it will wipe all partitions and setup 2 fresh ones, one fat32 and the rest ext4 for raspbian wich will fill drive) then shutdown and remove the sd card and the power up and it should boot from the hdd

if you need to resize or add more partitions use gparted after setup

this is how i setup my hdd install of retropie for my gaming-pi
