What are the advantages and disadvantages of each of UEFI+GPT and BIOS+MBR

1. GPT can use hard disks larger than 2.2T, MBR cannot. The maximum volume supported is 18 EB (1EB=1048576TB).

2, GPT can support unlimited partitions, Microsoft's current limit is 128. Linux, ubuntu, macos can support this partition format. MBR up to 4 primary partitions, more than 4 re-partitioning can only be done through logical partitions.

3, GPT partition disk has a backup partition table to improve the integrity of the partition data structure.

4, UEFI + GPT boot boot faster, boot skipped peripheral detection, and can realize the boot native resolution, equipped with a solid state drive boot time is very short, about ten seconds. （

5. UEFI + GPT supports Secure Boot, which improves security by protecting against bootkit attacks through the pre-boot or preboot process. All technologies that load earlier than the Windows kernel at boot time to achieve kernel hijacking can be called Bootkit.

6. UEFI BIOS can be used with a mouse to operate the graphical interface, no longer the boring white letters on a blue background in English. (Intel proposed to replace the BIOS.) The superior characteristics of UEFI: operability, security, compatibility, scalability.
