Does win7 hard disk format require mbr or gpt?

As for whether win7 hard disk format requires mbr or gpt, you still have to choose according to the details of your own system and hardware configuration. In terms of compatibility, it is best to choose the mbr format.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Win7 hard disk format requires mbr or gpt? When we use the win7 operating system, sometimes we may encounter situations where we need to reinstall the system and partition the hard disk. Regarding the issue of whether win7 hard disk format requires mbr or gpt, the editor thinks that you still have to make a choice based on the details of your own system and hardware configuration. In terms of compatibility, it is best to choose the mbr format.

1. If the system is installed with Win7, it is recommended to use MBR, which has good compatibility.

2. If it exceeds 3T or is installed with win8, you can use GPT.

3. Although GPT is indeed more advanced than MBR, MBR is definitely invincible in terms of compatibility.

The differences between GPT and MBR are as follows:

1. The number of supported partitions is different

1. The hard disk in the MBR partition table supports up to 4 primary partition disks.

2. GPT partition table type hard disks are not limited by the number of partitions.

2. Supported hard disk sizes are different

1. MBR only supports hard disks up to 2TB.

2. The GPT partition table type supports a maximum hard drive of 18EB.

1EB=1024 PB, PB=1024 TB.

2. The severity of damage is different

1. MBR has its own startup code. Once the startup code is damaged, the system cannot start. The system can only be started through repair.

2. GPT reduces the risk of partition table damage. GPT saves a copy of the partition table at the end of the hard disk.

3. Different development trends

1. GPT is a new standard that is gradually replacing MBR.

2. The GPT disk drive capacity can be much larger, so large that neither the operating system nor the file system can support it.

It also supports almost all 64-bit win0, win8, win7 and Vista, and the corresponding servers can be started from GPT.

4. Different partition information storage

1. In MBR hard disk, partition information is directly stored in the master boot record (MBR).

2. In a GPT hard disk, the location information of the partition table is stored in the GPT header.

5. Different compatibility

1. MBR has the best compatibility.

2. GPT partition compatibility is not that good. Therefore, at the very beginning of the GPT partition table,

3. For compatibility reasons, a traditional MBR is still stored.

4. It is used to prevent misidentification by hard disk management tools that do not support GPT. and destroy the data in the hard drive.
