BIOS RUINED MY LAPTOP

I own a lenovo 310 Ideapad laptop for almost a year. I was actually quite pleased with it until…
I get a message FROM LENIVO saying there is a critical update to BIOS that I must install so I install it. Immediately after I can no longer boot past the blue screen of death. Called Lenovo support since PC is still under warranty. My only option is to send the computer to them at my expense and they will wipe all of the info off the machine and reset to factory new status. What about the programs and data I will lose? Not their problem!!!
