After building your ISO image successfully, you should test it on your target machine. This guide explains to you how to test your ISO image.
Building the USB Stick
Depending on your build OS, they have their own procedures to create a bootable USB stick.
On Debian, you should follow their documentation based on your distribution. Here is an example for Debian Stretch: https://www.debian.org/releases/stretch/amd64/ch04s03.html.en. In any cases, you should be doing:
$ cp debian.iso /dev/sdX $ sync
Boot and Install
Once booted into the USB stick, you should select either
install. This will perform the automated installation designed by you.
Depending on the contents and network connections, the setup can take a very
long time. Grab a cup of coffee and wait for its completion.
IMPORTANT NOTE: Although Granatum strives to build headless installation, you still need to watch over it just in case there are new prompts or failures due to misconfigurations.
ONLY WALK AWAY WHEN THE HEADLESS INSTALLATION IMAGE IS TESTED WORKING PROPERLY.
TIP: During the installation while testing, we suggest you do
CTRL+ALT+F4for its debug console. This way, you can know what's going on from the backend.
To switch back to frontend, it is
CTRL+ALT+F1if you selected install or
CTRL+ALT+F5if you selected graphical install.
