Win7 hard disk format requires gpt. The reasons are: 1. The UEFI system can better support the GPT format, can take advantage of GPT, and provide more functions; 2. The hard disk capacity used If it exceeds 2TB, GPT is a must, and MBR cannot recognize hard disk space exceeding 2TB; 3. GPT supports more partitions, making system management more flexible.

When choosing the Windows 7 hard disk format, we can choose to use MBR (Master Boot Record) or GPT (Guid Partition Table). These two formats have their own advantages and applicable scenarios in different aspects.
First we need to understand the basic concepts and differences between MBR and GPT.
MBR is an early hard disk partition table format that was widely used in the early days of computer hardware and operating systems. MBR manages the partitioning and booting process of the hard disk by recording the partition table and starting the boot program in the first sector of the hard disk (usually 512 bytes). However, MBR has some limitations, including supporting up to 4 primary partitions or 3 primary partitions and an extended partition (which can contain multiple logical partitions), and the maximum partition capacity is limited to 2TB.
GPT is a newer hard disk partition table format that introduces many new features that MBR does not support. GPT uses the first and last sectors of the disk to store the partition table and backup partition table, making the partition table redundant and fault-tolerant. In addition, GPT supports larger disk capacity (up to 18EB) and more partitions (almost unlimited). GPT also has stronger security and reliability, including detecting and correcting data corruption and providing disk-level data. Based on the above principles and considerations, we can draw the following conclusions:
If your computer hardware ( Including motherboard and BIOS) supports UEFI (Unified Extensible Firmware Interface), then GPT format is the first choice. UEFI is a newer firmware interface standard that replaced the older BIOS system. UEFI systems can better support the GPT format, take advantage of GPT, and provide more functions.
If the hard disk capacity you use exceeds 2TB, GPT is a must. MBR cannot recognize hard drive space exceeding 2TB, so large-capacity hard drives cannot be fully used.
If you need more partitions, or use multiple operating systems on the same hard drive (such as dual system or multi-system boot), then GPT is also a better choice. GPT supports a larger number of partitions, making system management more flexible.
If your computer hardware and operating system are relatively old and do not support UEFI, and your hard drive capacity is less than 2TB, then MBR is a viable option. MBR is the default legacy format and is suitable for these older hardware and operating systems.
Summary
We recommend choosing GPT format if possible. The GPT format has better compatibility and scalability in terms of hard disk capacity, number of partitions, and functions. However, the choice should be made based on the actual situation and the support of the hardware platform. Make sure to choose the hard drive format that suits your needs.
