Windows 8 (Preload) : Unable to select Legacy Boot option

Question

I just got my ThinkPad T430u with Windows 8. Under BIOS menu I can't select the Legacy boot option as it is greyed out and unselectable. Is this something common with all the new factory installed win 8 Thinkpads?

Answer

Win8 logo requirements from Microsoft means that the Win 8 preload system ships with UEFI enabled, SecureBootenabled, and Legacy Boot disabled.  This makes it impossible to boot anything other than Win8.

 

To boot something other than Win8 UEFI mode, you have to disable OS optimized defaults and then load default settings.  This option is in the Restart screen of BIOS setup.
