For installing a server with a partition greater than 2TB, which boot mode is required?

To install a server with a partition greater than 2TB, the required boot mode is UEFI (Unified Extensible Firmware Interface). UEFI is a modern firmware interface that replaces the traditional BIOS and includes features necessary for booting from drives larger than 2TB.

The reason why UEFI facilitates the use of larger partitions is due to its support for the GUID Partition Table (GPT). GPT allows for more efficient partitioning and supports disks larger than 2TB, accommodating up to 128 partitions on a single physical drive. In contrast, BIOS supports only the Master Boot Record (MBR) partitioning scheme, which limits partitions to 2TB and a maximum of four primary partitions.

While GRUB (the Grand Unified Bootloader) is a bootloader frequently used in conjunction with UEFI, it does not directly dictate partition sizes. Therefore, it does not serve as the correct answer to this question concerning the installation of servers with partitions greater than 2TB.

In summary, UEFI is essential for supporting modern storage technologies and larger partitions, making it the correct choice for installation scenarios requiring partitions exceeding 2TB.
