Hello @dinetta,
You can achieve this by using a single FAT32 partition on a SD card.
In this partition you can copy the Toradex Easy Installer files and the folder with your custom image which is configured to auto-install.
This way when the device is turned on, it will boot to Toradex Easy Installer and the image will be auto-installed.
Here is an example of how this can be organized:
$ lsblk -l -o NAME,FSTYPE,SIZE,TYPE -d /dev/mmcblk0*
NAME FSTYPE SIZE TYPE
mmcblk0 14,8G disk
mmcblk0p1 vfat 14,8G part
$ tree
