Windows 7: Why would you need UEFI if 64 bit system is suppose to protect

3d Jedi, I think you are mixing things up. MBR has nothing to do with UEFI. MBR is a hard drive partitioning scheme. Having a UEFI motherboard does not remove support for MBR.

UEFI enabled Board and Bios settings can be set to UEFI secure boot but you still can choose an install of your operating system to Legacy Boot or UEFI Boot, which last one will remove the MBR support to the prefered GPT scheme. New Bios must have bynow the UEFI secure boot enable along the CSM enabled or not, by default because of new coming OSes started by Windows 8.

That is only for OEMs that want a "Windows 8" sticker legitimately slapped on their hardware. Even then Secure Boot is optional.

Last Bios versions of my motherboard have set to default the UEFI Mode & secure boot to enable...CSM is disable by default. I'm on retail version of Windows 7.

Since it does not interfere with Legacy boot i have decided to let it as the last Bios provided set it.

You really only need to enable CSM if you want to install a Legacy OS like Win7. Windows 10 even runs under Secure Boot, although I had to disable it the other day to boot the Macrium Reflect PE disk.

Mobo's are migrating to GPT/UEFI and when it's 100%, MBR activation hacks will be history. Meanwhile . . . MS has changed the Windows 8 OEM serial mobo malarkey so every system has its own key (thus rendering any MBR hack attempt pointless), but the hackers are already on the case. MS left the door open with KMS volume activation. The hackers now have a tool that emulates volume Windows 8 activation, and it can be set to run at startup, giving a constant 180 days before re-activation required.

By policy, Windows 8 and Windows 8.1 require UEFI firmware to boot the operating system. UEFI provides basic services such as access to the boot device in the pre-boot environment. Windows Server and earlier versions of Windows client do not require UEFI mode and can boot either from traditional BIOS or from UEFI if this is supported by firmware. To enable booting these operating systems on a computer that uses UEFI, Compatibility Support Module (CSM) in UEFI provides compatibility support for traditional BIOS. Windows 7 and earlier versions of Windows require INT 10H support for boot graphics. This is provided by CSM in UEFI mode. The CSM can also be used to fully support traditional BIOS mode on a system that has UEFI firmware. These modes are known as Class 2 UEFI mode and Class 2 BIOS mode.

3d Jed,
If that was the case, I would had to activate my operating system when dell replaced the motherboard, didn't have to do that & it was a vlk. Also, the OEM key on the back of the computer wouldn't have worked to activate windows 7 via the internet, when I did unorthodox reinstall of windows 7 oem without violating the EULA.

Does Secure Boot or UEFI really protect from malware & rootkits?

Doesn't UEFI with Secure Boot on or off, boot using a fat 32 partition? I thought Fat 32 was insecure?
