I am getting ACPI BIOS BoS (Error 0x000000A5) during Windows Setup (XP,Win8), While one Win7 (32bit/64bit) it just restarts back Leonovo Boot Screen while tries to load the Setup GUI, or even with "BIOS is not fully ACPI compliant" error.
I've tried to boot with Hiren Mini Xp , Backtrack 3, Backtrack 4, Backtrack 5 all prompt error that can't get ACPI.
Every possible BIOS settings have been attempted but nothing work. The system can pass the memory test for 2 hours with no error.
You should try to get the latest BIOS version 41A or above to support Win 7 installation.
The BIOS flashing process is not easy and may cause other unexpected issues if you're not a techie to handle such situation.
Hence, please seek assistance from the nearest service centre by describing your issue in details otherwise engineers will not flash BIOS for you without a reason.
If you have the knowledge of flashing BIOS by yourself, kindly drop me a PM or check with our Guru or Moderator for more info.
