After my hard drive crashed, my brother installed a new one for me. I ordered recovery discs from Sony and he installed them also. The computer couldn't detect any operating system from what he told me so since I misplaced my Vista Home Edition he installed XP Professional. After not being able find any drivers for my Sony Vaio model VGN-FE855E I found out that my notebook is not compatible with anything besides Vista. Sony Tech people told me I should find my operating system on the recovery discs the sent me. Im trying to run them but I have a message saying: "The recovery drive letter is the same as the system drive letter". What does it mean and why I can't get my system recovered?
