Shrink Raspberry Pi Images - Using Windows, Virtualbox running Raspberry Pi Desktop

in #raspberrypi3 years ago (edited)

Massive Pi Images are a pain as they take too long to write to a sd card, so trimming them down speeds up prototyping.

My personal "setup pi image" is 3gb which is all the apps and setting I want for a fresh Raspberry Pi, which has ssh, vnc, ect installed while all the stuff I never need is removed.

Tools required:
-USB memory card reader
-Win32DiskImager (available from sourceforge)
-Virtualbox running Linux ( I am running Raspberry Pi Desktop available on the raspberry pi website, you could Ubuntu ect)

Before we begin make sure that you have expanded your Raspberry Pi file system.

Choose "Advanced Options" then "Expandfilesystem"
In the terminal type: sudo raspi-config

Before starting, backup your raspberry pi image using Win32DiskImager encase something goes wrong!

Backup your image.

Step 9:
Move the slider and leave a gap to fit the file system in, I leave a couple hundred megabytes just to avoid issues.

Step 10:
Nothing has changed yet, you need to click "Apply All Operations".

Step 11:
Wait it takes a few mins.
