I will be installing Windows 10 Pro 64bit on a new custom PC with a 1tb primary disk only.  I've been reading about the difference between GPT and MBR disks and I'm undecided about which format to use.  I've never had a computer using GPT and I'm a bit nervous about making this change.  Can someone offer me suggestions or recommendations?

Thank you for this link but much of the technical information provided is beyond my scope.  I am sure my new system will support UEFI.  I am not planning to have more than four partitions on this drive and its capacity is less than 2.2gb.  What benefits does GPT provide?  Is the secure boot feature available on MBR drives?  Rather than a technical report, I am seeking a recommendation as to which format will give me the best system performance and protection in the future.  Is the disk format totally tranparent once the operating system is loaded?

The Secure Boot is feature of UEFI firmware and you need GPT disk to use Secure Boot.  MBR disk support disk storage size of 2.2 terabytes (TB) where as GPT disk support 9.4 zettabytes (ZB).  The MBR can only define up to four primary partitions on a disk of just under 2.2TB in maximum size, BIOS based systems cannot boot from a drive that is 2.2TB or greater in capacity. The GPT  format design that supports up to 128 partitions on a disk of up to 9.4 zettabytes (ZB, where 1 zettabyte = 1 billion terabytes or 1 sextillion bytes).

Just use MBR and you will be fine. I built this new high tech PC and I still use MBR and I don't notice any difference. Everytime that I do a clean install of Windows I just do it and I let the cards fall where they will. If I end up with MBR or GPT it does not make any difference.

 

On a different note. Is that 1 tb drive an old fashioned spinning hard drive or a new SSD? Your system would be much faster and secure and durable if you add a little 250 gb SSD just for your C: drive and use the 1 tb drive just for your data.
