I have a similar problem, I have windows 7, when I start my laptop after some time it brings me to the screen where there is an option to select system repair or start windows normally. This happens everytime. When I click system repair, it keeps on loading the repair then freezes, if I click start windows normally, it goes to the windows loading screen and freezes. And I can't detect that hard drive from another operating system on the same laptop but different hard drive
