Windows 7 clean installation on SSD using USB stick

[IDXIII]

I have a Lenovo ThinkPad P50 with 250 GB Samsung SSD and every time I try to install Win7 using a USB stick, the installation starts normally until it should show me the partitions on which the windows should be installed and it ask for some kind of a driver.
Please I need your help with this problem (please note that there is a windows 7 already installed on the laptop and all the USB ports are USB3).

The fact that your USB ports are of the USB3.0 variety is where the problem lies. You will only be able to continue the installation once you have installed drivers for your USB.
