N5110 BIOS Problem While Installing Windows 7 OR 8

Dear Sir,

This is Hardosh Kumar,

I changed laptops Hard Disk, and When I am trying to Instal Windows 7 or 8, after completion of Installation, When windows goin to setup Desktop, It show error in blue screen and shows error that Update BIOS, but I already have updated BIOS Version A11. I tried to update BIOS with A11 message is appearing can not flash BIOS with same version. I need to install Windows 7.

Kindly suggest me What should I have to do.

Before changing of Hard disk, I was using Windows 7.

Thanks Alot
