Hi,
I have a Dell inspiron 15 3000 series since 2 years now. It has recently upgraded to wimdows 10. Everything was fine. I used it even yesterday and shut it down properly. But this morning when i started the laptop it remains stuck on the screen with the Dell logo (see image). Even if i do F2 or F12 nothing happens. It does not switch to the bios screen.

Thanks.
