OK - it doesnt recognize my 32GB flash drive - i dont have others over 4GB - i dont have DVD to boot from my only option is to install it from the HDD (the internal one) If i run the installer under the current OS X version (2 years old) it installs it on top of it and keeps all the settings and stuff. I want to start clean with the last OS X. How to do that? Please note that my only option seems to be installing it from the internal drive (dont even have internet where the mac is located, wont be convinient to move it). So how to install it clean from the HDD?
