So, I have a Dell laptop. The model is Studio 1747, using Windows 7. Not long time ago I had a virus problem with another computer and I gave up, because I was unable to repair it and I simply restarted the computer from the begining by using the Factory Image. I was quite easy, since the option appeared during the starting screen. Now, I was wondering if I could do the same with my Dell laptop, it's in perfect state, but just in case, it would be useful. I went through the things that I recieved with the computer and among them, I found the manual and it says that during the starting screen (when the Dell Logo appears) I had to press F8. Though, it does nothing, in fact the screen doesn't mention that F8 does anything. So I tried F12, which the screen says to "boot options". So I did, but all I had was the choice to boot from the hard drive or DVD/CD or USB and of course "exit".
