I am trying to create a duel-boot Apple iMac, using Mac OS on the internal drive and Elementary on an external drive. I've gotten a bootable version on a USB thumb drive and explored the Live View, but when I look at the instructions for installing it for real, the instructions are very laking.
If this is going to be easy, and non-anxiety inducing, to do, the instructions should include screen captures of all the installation steps and/or some description of what choices you'll have for the installation.
There is no assurance that the installer will allow me to select any drive connected to the computer for installation (and avoid over-writing my internal drive.)
I've gone through the process twice and each time I've stopped when it wasn't clear that my next click was not going to erase my internal drive. The warnings to have a back up of important information just make me more suspicious that I wouldn't be able to select an external disk for installation.
This is all very simple and obvious to the developers, but not to the people who are curious to try LINUX and have no LINUX background.
