I am Japanese Dell User.    My laptop is E5510, and BIOS version is A07.Though original OS of my E5510 is Windowes7 pro 32bit, I am trying to change os to Windows 7 Pro SP-1 64bit version.But , 64bit OS installation was failed. Clean install of 64bit OS was passed.However at device driver installation stage, I encountered windows 7 installation error.Based on dell instruction, I installed  Dell System Software, Intel Chipset installation utility, Ricoh R5U24X, Intel AMT HEIC, Audio device Driver, Video Driver.Then I installed NIC driver (Broadcom 57XX GIGABIT controller, Intel wireless network driver), Dell Multi-touch touchpad, Windows installation was failed and shift to recovery installation mode. But Recovery failed.I think BIOS update is one of possibility to solve 64bit OS installation problem, I planned BOS updating A7 to latest revision(A16)).By dell web, BIOS revision A9 and previous revision should be updated A10, andthen updated A10 to A11, A12,,,, A16. So, I plan to update BIOS by two steps, 1st step  A07 to A10, 2nd step A10 toA16.But I failed BIOS update at 1st step(A07 toA10) as described below.
