Windows install - MBR VS GPT

post #1 of 3
Thread Starter 
I am interested in information comparing: Windows install to MBR partition vs UEFI Windows install to GPT partition.

Some things I have heard, but without much evidence...
"UEFI boot would be way faster"
"GPT paritions are more secure and have redundancy"

Any info would be much appreciated.

I am no expert here but I also heard good things about GPT and the things you said are true I suppose.

I think when I get a board with UEFI I am gonna use GPT personally.

GPT has redundant partition tables so they stand a better chance of recovery should one of them becomes corrupted. If the partition table of an MBR disk is corrupted, you are basically SOL and need to restore from backup. Also GPT can have more primary partitions than MBR. Microsoft supports 128 partitions on a single GPT disk. MBR is limited to 4 primary partitions (or 3 primary and 1 extended partition).

GPT is also required for large RAID arrays.

If you can use GPT, you should if your software is compatible. An issue is that you need a UEFI motherboard to boot from a GPT disk. 32-bit OS cannot access GPT disks iirc. Older versions of Windows like XP, 2000, and older versions of Linux may not support GPT iirc. Manufacturers stick with MBR since it is most compatible with older software. Also GPT will use a miniscule more amount of disk space than MBR because of the redundant partition tables.
