Guides/Changing the Boot Image

So, you've got a pretty Shift ISO, but now you want to brand it, with Shift graphics. This tutorial will help you change the boot image from Morphix's default image to your own (Shift-related) image.

Step 1:

Inside your ISO directory (before running make-iso), navigate to /boot/grub/ and open up and extract files from message to a directory outside of the ISO directory (ex. /home/user/message), by going to that directory (/home/user/message) via Terminal and typing:

cpio -iv < /real/message.cpio

Step 2:

Open up the GIMP and your image file. Save it as a PCX file, and name it background.pcx. Move it into your message directory (/home/user/message). You should have overwritten the existing background.pcx file.

Step 3:

(Tedious, but necessary as I know) Make a file in the message directory, call it files. Open it up in a text editor and type in a list of all of the files (excluding the files file you're in now), using a ./ instead of /home/user/message. Save it and close the editor.

See the Alternate below.

Step 4:

Open up the Terminal and cd into your message directory (home/user/message). The following command will create a special type of archive used by GRUB during boot. Type it in.

sudo cpio -o <./files> ./message

Step 5:

Now, copy the new message archive you just made into your ISO directory (/boot/grub/)

Make the ISO and boot up. Cross your fingers, and edit this if you find an error, or if you can do it better!

Alternate to Step 3-4, not tested:

Change the directory in Terminal to /home/user/message, or wherever you put the extracted files and type:

ls | cpio -o > message
