GPT UEFI
The GUID Partition Table (GPT) along with the Unified Extensible Firmware Interface (UEFI) have revolutionized the way computers boot and handle storage. GPT is a partitioning scheme that replaces the older Master Boot Record (MBR) system, while UEFI is the modern firmware interface that replaces the traditional BIOS. This article will explore the benefits and features of GPT with UEFI, and how it has improved the overall performance and security of modern computer systems.
Key Takeaways:
- GPT and UEFI have replaced the outdated MBR and BIOS systems.
- GPT allows for more flexible and efficient disk partitioning.
- UEFI offers enhanced security and faster boot times.
- GPT with UEFI provides support for larger disk sizes and more partitions.
Improved Disk Partitioning with GPT
GPT allows for a more efficient and flexible way to partition disks. Unlike MBR, which was limited to only four primary partitions, GPT supports up to 128 partitions. This enables users to create more logical partitions, such as separate partitions for the operating system, data storage, and recovery tools. GPT also provides redundancy by storing a backup header and partition table at the end of the disk, reducing the risk of data loss due to disk corruption.
