I got a Sony Vaio svf1521z1eb. I bought it couple of days ago with win8 on it, so i decided to downgrade to win7. The problem is that several drivers arent working so i want to go back to win8. The thing is that i changed boot option in bios so i can install win7 but in order to go back to win8 i need to undo thoses changes. And here the thing : i cant access bios anymore. I've tried every key during start up logo and it doesnt work. Any thoughts ?
