I think if you're going to go with this type of menu it needs making a little more newbie friendly. Even just changing a few little things to be more explicit as to what does what can help. Like -
Start live environment from CD/DVD/ISO: etc..
Start live environment from Stick/HDD: etc..
The driver bit might be confusing as newbies might not know what that's about, so not really sure what to suggest with that.
As the menu is right now the 'From ...' bit isn't obvious that's what gets things going.
I wish I could help design something easy to use, I'm not very good at doing graphics tho. I'll just have to stick to making suggestions lol
Would it be possible to use the mouse to select keyboard/language and the various options ? maybe in dropdown boxes/icons or something and have that remembered/picked up as the default when you get to the installer (calamares is it ?)
Just a few ideas really, I'm cool with the installer as it is
