  1. Hi there
    I followed the guide but after loading the windows files, I have to choose which language to install, what happens here is the system freezes. I cant use neither the keyboard nor the mouse. I know the disc I used for copying over the W7 files is OK and usb legacy support is enabled in the BIOS.
    Why the freezing/no contact with mouse and keyboard?
