How to change isolinux folder of an ISO image?

Asked by imagemturbo

I'm editing Xubuntu (xubuntu-20.04.1-desktop-amd64.iso) with Cubic (Custom Ubuntu ISO Creator).
I need to change the logo image that appears in the menu when booting into BIOS mode when we press any key. https://i.stack.imgur.com/0Wlv2.jpg
Canaged to edit and package the bootlogo file that is in the isolinux folder,
but I did it outside of Cubic using a system in Live mode to have normal access to the isolinux folder.
How to change isolinux boot splash?
Is there any way I can do this inside Cubic and already leave my custom ISO with the isolinux folder and the bootlogo file I made previously?
I searched here on this site and in internet forums and I couldn't find the answer.
Thank you very much in advance!

When you navigate to the Options page in Cubic, you will see three tabs at the top: Kernel, Preseed, and Boot.

1. Click on the Boot tab.

2. Then click on the "Show all files" toggle button at the top left of the header bar. (It is the 1st button to the right of the "<Back" button).

3. This will expand all of the files in the "/boot/grub" and the "/isolinux" folders.

4. You can use the buttons in the header bar to copy files into these folders, create new files, or delete files. Note that the header bar buttons change, depending on whether you've selected a file or a directory in the tree view at the left. So, fore example, to create a new file in a directory, you must select the directory first, in order to activate the "Create a new file" header bar button.

5. You can view and edit text files by selecting them in the tree view on the left side. Your changes will automatically be saved when you click the Next button. (By the way, files you add or update will automatically be shown in the default list on this tab, so the next time you launch your Cubic project, you won't need to click on the "Show all files" toggle button.)

I really enjoy working with images, no matter how difficult the task may seem. With the advent of stock photo sources like https://depositphotos.com/stock-photos/halloween-background.html it's even easier to find any image you need, from Halloween backgrounds to complex shots. It has greatly simplified my work and made it much more enjoyable.
