I have recently downloaded and attempted to install Mavericks on my AMD based machine. I changed all my BIOS settings to the required settings and wrote the .dmg file to a 16GB USB and booted from it. I got as far as the screen where you select where you want to download the OS, but my Hard Drive does not show up. I partitioned 100GB of it and still it did not show up. Am I doing something wrong? Did I not install the right Distro? A solution to this problem would be great, thanks guys!
