Thinking about going MBR rather than GPT on a new MOBO

Hi,

my friend is building a new PC and he'll have a GIGABYTE MOBO, LGA1150, IH97 (GA-H97-HD3 model).

He'll be running Windows 8.1 x64 on it and have a 240 GB SSD, a 1 TB HDD and an optical drive.

So, should he go with MBR or GPT? He's leaning towards MBR for compatibility reasons (and since his drives are smaller than 2 TB).

What should be canged in the Gigabyte UEFI to make it work with MBR disks? Secure boot? CSM? What about fast boot? Mode is still AHCI, right? What else?

In real world, from your experience and looking practically, would you suggest going MBR or GPR? Are there any real benefits (security and performance wise) using GPT and UEFI secure boot and whatnot?

Thank you!
 
Windows 8 features Secure Boot. This prevents malware from hijacking your boot process and concealing itself from your operating system. Secure Boot prevents “unauthorized” operating systems and software from loading during the startup process.

Secure Boot is a feature enabled by UEFI – which replaces the traditional PC BIOS. When Secure Boot is enabled, the compatibility support module (CSM) must be disabled so that the PC can only boot authorized, UEFI-based operating systems.

Enabling UEFI Secure Boot with a Gigabyte BIOS.
1.Install Windows8 in UEFI mode
2.After Windows 8 completed installation, reboot to CMOS options, and change
OS Type: Windows8
3.CSM Support: Never
4.Secure Boot can now be Enabled and Secure Boot Keys installed.

Secure Boot also requires GOP (Graphics Output Protocol) support detected in the video card.

SATA Mode Selection by default is AHCI.

Hm, everyone is telling me different, on other forums too. I don't know if I should go with MBR and legacy boot or GPT and secure boot... I'd like all the new features, esp. max speed/performance but having disks compatible with older systems in case of failure and date recovery is always a good thing too. I really don't know what to do...

Anyway, thank you for your comments! :)
 
Everything that I have read about secure boot does not mention anything about GPT or MBR. Including this article that I just read.

If someone has any links that will explain better the need for GPT mode just for secure boot, please share them here. Old dogs can learn new tricks.....
