BIOS+MBR: This is the most traditional, the system will support; The only drawback is that hard disks larger than 2T are not supported.
Bios+gpt:bios can use GPT partition table hard disk as the data disk, but can not boot the system, if the computer with a capacity of less than 2T hard disk and capacity greater than 2T of hard disk, less than 2T can be used MBR partition table installation system, and more than 2T can use GPT partition table to store data. However, the system must use a 64-bit system.
, UEFI+MBR: Uefi can be set to Legacy mode (traditional mode) to enable it to support the traditional MBR boot, but is purely blind toss, bring the effect with BIOS+MBR; You can also build FAT partitions, place UEFI boot files, and apply dual-mode boot on USB and removable drives.
