I have created a LiveUSB to install Linux Mint 14.
When I boot my PC from the USB key, Linux Mint starts properly.
When I choose to launch "Install Linux Mint", when the Installation Type screen is displayed, I can't select HDD for the install. Only /dev/sdb device is shown.
I have also run gparted and my internal HDD is recognized (160 GB). I have suppressed all partition, without any success: installer does not propose to install Mint on HDD.
