I got a Dell latitude E5500.from my sister. I want to reinstall the operating system but I can't get into the bios. When I turn the laptop on it goes into the Win xp splash screen so fast. I have tried holding down the exc key, F1, F2, F8, F10 and F12 to no avail. The problem is it hangs on the Win xp screen and never goes further
On most Dell's, when you start it up, for a brief moment there is a black screen with <F2> for BIOS, <F12> for boot options. Instead of holding the F2 key, try pressing it multiple times before Windows logo shows.
Also - on some laptops, you can go into BIOS only from complete shutdown state.
