Re: lenovo T440 installing os

Hi redzone2005,

Warm Greetings & welcome to Lenovo Community, happy to have you here.

As I understand that you have query regarding OS installation in T440. 

The OS Optimized defaults is basically required when you are installing Windows 8 and above.

And if it is enabled, some other settings are changed automatically, such as CSM Support, UEFI/Legacy Boot, Secure Boot, and Secure RollBack Prevention. 

And here are few links for Clean installation of Windows 10 & Windows 7 

 

I hope the above information helped you.

Please provide the requested detail to proceed further.

 

Regards,
Prabhansh
