Best way to boot from HDD?

[Fourdee]

@Cheesethief

Does the DietPi installation do this when I select that I have an external HDD? Or does it just install programs to the HDD, while keeping rootfs and everything still on the SD card?

If it does not, is it recommended that I do what I did above before running initial setup where it asks me about how I will be using the pi?

If you selected USB drive, DietPi will use your external HDD for software configurations that have personal data paths.

Some examples:

• owncloud will be setup to use /mnt/usb_1/owncloud_data
• All software that has a Music path, will use /mnt/usb_1/Music
• All software that has a downloads path (bittorrent) will use /mnt/usb_1/downloads
  etc etc.

The SD card’s 2nd partition is left as is and does not move to your USB drive.

If you want to move the SD contents over to USB, your best bet would be to:

• run a fresh install of DietPi
• Say no to the USB drive prompt.
• Complete your installation of software

At this point you can use your previous steps to reconfigure your RPi to use the USB drive.
