The drive does not have a primary partition or a logical partition

It is better to partition with XP installation disk.

How it works: Set aside a small blank disk, create a new partition behind the blank disk, convert it to a logical partition, and then resize the partition.

Create two new partitions and delete the first partition.

Logical partitions cannot be converted to primary partition resolutions.

The second partition is converted to a logical partition.

Logical partitions cannot be converted to primary partition resolutions.

Save it. Logical partitions cannot be converted to primary partition resolutions.

Resize the second partition.

Logical partitions cannot be converted to primary partition resolutions.

Logical partitions cannot be converted to primary partition resolutions.

The conversion is complete. Logical partition cannot be converted to primary partition workaround step reading.

Logical drive A volume created in an extended disk partition of a base primary boot record (MBR) disk. Logical drives are similar to primary disk partitions, except that each disk can have a maximum of four primary disk partitions, and there is no limit to the number of logical drives that can be created on each disk. Logical drives can be formatted and assigned a drive letter.

A logical drive is generally called a number of partitions of a hard disk. Before a new hard drive can be used, it must be partitioned. In order to make better use of the hard disk space, we usually divide its overall space into several areas, we look at the hard disk in the operating system, for example, in the "My Computer" of Windows, we see that there are "local disk (C)", "local disk (D)", "local disk (E)", etc., it seems that there are multiple hard disks (multiple physical drives will also behave in the form of the above), in fact, logically they are on a hard disk, these hard disk partitions, we call logical drives.

Take Huawei MateBook-X and Win10 as examples. The main differences are different from different subjects, different characteristics, and different segmentation. 1. The main body is different:

The primary partition, also known as the boot partition, is a type of partition like the extended partition and the logical partition. A logical partition is a contiguous area of a hard disk, while an extended partition can be divided into multiple logical drives. <

Demo model: Huawei MateBook X System version: Win10 Take Huawei MateBook X and Win10 as examples.

The main differences are: different subjects, different characteristics, and different segmentation.

First, the subject is different.

1. Primary partition: also known as boot partition, it is a type of partition like extended partition and logical partition.

Second, the characteristics are different.

1. Main partition: The activated main partition is the boot partition of the hard disk, which is independent and the first partition of the hard disk.

2. Logical partition: Each logical partition has an extended boot record (EBR) similar to the MBR structure, and the first entry of the partition table points to the boot sector of the logical partition itself, and the second item points to the EBR of the next logical drive.

Third, the fragmentation is different.

1. Primary partition: The primary partition is independent, corresponding to the first partition on the disk, and cannot be divided.

2. Logical partition: The extended partition can continue to be extended and divided into multiple logical partitions.

Partition 1, Partition 2 ......It refers to the number of the partition on the hard disk. Generally, the first in partitioning is partition 1; However, if there is a special partition (like the hard disk in the figure), it is necessary to identify the size of each partition in advance (you can use win pe to start the system and then check the files in each partition to determine the size of each partition).

Determine the number of partitions to which Windows should be installed according to the size. By default, the system will divide the first three partitions with the fourth partition as the primary partition.

1. Re-creating partitions and deleting partitions will affect the data, so it is recommended that you save your important data to the U disk or network disk in time before the operation to avoid irreparable losses.

2. Now most computers are a combination of dual hard disks, that is, solid-state drives and mechanical hard disks as a whole, here it is recommended to use solid-state drives as system disks, although the solid-state capacity is small, but there is no problem with installing a system, the most important thing is that the processing speed of the solid-state disk is fast, and the system can improve the running speed of the computer by installing it in the solid-state.

In this case, the drive refers to a physical hard disk.

There are several hard drives, there are several drives.

The partition here refers to the storage space divided on the hard disk.

A hard disk can have multiple partitions.

There is no limit to which partition is the primary partition, and it has to do with the partition configuration and the hard disk partition table. With GPT on the figure, the fourth primary partition is normal.

Partition 1-3 is a high version of the Windows system reserved partition capacity is very small, because it is a reinstallation, so there is a partition of the previous system, if it is a new hard disk, its own partition, the system will default to the division of the first three partitions to the fourth partition as the main partition, and after installation, the one, two, three partitions are hidden in the system and cannot be seen.

1. "Primary partition" refers to "the only bootable partition".

2. The "bootable partition" does not necessarily have to be used to store the operating system, and the operating system can be stored in the non-bootable partition, but the "bootable partition" must have the boot head of the operating system, which generally does not exceed 10mbyte, and most users will not feel its existence.

3. After the logical drive is divided into regions, the operating system should logically organize the partitions. Different operating systems have different logical organizations, which is why they are usually called DOS partitions, Windows partitions, Unix partitions, Novel partitions, and Mac partitions.

4. For the same operating system alone, the storage logic of programs and data is not the same, and it is not safe to put programs and data together, so an operating system often manages a variety of different partition types.

A primary partition, also known as a primary disk partition, is a type of partition just like an extended partition or a logical partition. No other types of partitions can be partitioned into the primary partition, so each primary partition is equivalent to a logical disk.

In fact, in the early days of hard disk partitions, there was no concept of primary, extended, and logical partitions, and each partition type is now called a primary partition. Since the hard disk only reserves 64 bytes of storage space for the partition table, and the parameters of each partition occupy 16 bytes, the total data of the main boot sector can only be stored in 4 partitions. In other words, a physical hard disk can only be divided into 4 logical disks.

In specific applications, four logical disks often cannot meet the actual requirements. In order to create more logical disks for the operating system to use, extended partitions and logical partitions were introduced, and the original partition type was called the primary partition.

A hard disk partition is essentially a format of a hard disk before you can use the hard disk to save various information. When you create a partition, you have set the physical parameters of the hard disk, and specified the location of the master boot record (MBR) and boot record backups. For the file system and other operating systems, the information required to manage the hard disk is achieved through the subsequent advanced formatting, that is, the format command.

In fact, it is completely possible to create only one partition and use all or part of the hard disk space. However, no matter how many partitions are divided, and whether you are using a SCSI hard drive or an IDE hard drive, you must set the main partition of the hard disk as the active partition before you can boot the system through the hard disk.

The main partition is the location where the system files are stored, it is recommended that you do not move it, otherwise the system will crash! The logical partition is your application area, where your files are stored, and the use of your application area files will not be affected after reinstalling the system.

Main disk partition: Generally C, it is the C drive, which can boot up.

Expansion Disk Partition: Except for the primary disk partition, all other disk partitions are a Expansion Disk Partition.

Logical Drives: Expand the disk partition in the sub-logical drives, D, E, F......
