What does an active partition mean and how to set it up

The active partition is the boot partition of the computer, the boot files of the operating system are installed in this partition, the Windows system is generally defaulted to the C drive, when the system is booted, the operating system on the active partition will perform a process called drive image, which assigns a drive name to the main partition and the logical drive. All primary partitions are imaged first, while logical drives are designated with subsequent letters.

If you do not set the active partition, the system will not boot.

In the partition table of a hard disk, the partition with the 80 flag at the top of the 16 bytes is called the active partition.

The hard disk is divided into the main partition and the extended partition, and the extended partition is further divided into the logical partition. In a hard drive, there can generally only be one active partition.

The active partition is actually the main partition with boot data, which can complete a series of actions such as handover and boot tasks with the BIOS to boot the system.

In the Windows operating system, the system is generally installed on the primary partition marked as active and must be on the disk that the computer accesses when the system is booted. There can only be one active system partition on the same disk at a time.

The active partition is the boot partition of the computer and is also the system partition;

The files that boot the operating system are all installed in this partition, and the Windows system is generally defaulted to the C drive.

After starting the software, select the hard disk that has been loaded on the machine, select a partition, you can set it as "active partition", after setting the active partition, as long as the partition is equipped with an operating system, the computer will start from the active partition.

1. Main partition: in the front area of the hard disk.

No other types of partitions can be partitioned within the primary partition, so each primary partition is equivalent to a logical disk (in this respect the primary partition is similar to the logical partition, but the primary partition is partitioned directly on the hard disk, and the logical partition must be built in the extended partition). In the early MBR mode, partitions could only be divided into four partitions.

Connection: All belong to the computer field.

Primary partition: also called boot partition, up to 4 may be created, when creating four primary partitions, you can no longer create extended partitions, of course, there is no logical partition. The primary partition is independent, corresponding to the first partition on the disk, which is the C drive.

In Windows, all primary and logical partitions are called "disks" or "drives", and all storable media are displayed as "disks" of the operating system. Therefore, it is not possible to distinguish between a primary partition and a logical partition from the concept of a "disk". And the drive letter can be modified in the operating system, which is why the word "general" is added.

Active partition: This is the partition that is currently active and can be booted by the operating system.

In the DOS era, the primary partition can be booted, but the logical partition is not. The primary partition is mainly used to install the operating system. The formats are NTFS, FAT, FAT32, which are used under Windows.

But FAT doesn't need to. There are also linux uses.

The difference is that there can be more than one primary partition and only one active partition.

An active partition is when the primary partition is active. A hard drive can have multiple primary partitions, but only one active partition, which is the primary partition that is currently in use.

The new hard drive gets back the partition must have both the existing primary partition and the extended partition. The main partition that can generate the active partition files that boot the system is here, such as the commonly used C drive. There are many logical partitions that can be generated in the extended partition, such as d e f g h disks.

The boot files of the operating system must be installed on the main partition of the system.

For example, the main partition is C, the operating system is installed in the D drive, and there are definitely a few in the C drive, such as *sys file (startup file). Otherwise, it won't start.

The primary partition is the area where you install the system.

The active partition is the boot partition of the computer, the boot files of the operating system are installed in this partition, when the system is booted, the operating system on the active partition will perform a process called drive imaging, which assigns a drive name to the primary partition and the logical drive.

The primary partition is the boot partition, which is mainly used to install the system. Such as C drive. The active partition can be adjusted and merged at will, such as: D disk, E disk, F disk.

The main partition is the boot area, which is generally the C disk, and the rest is the active disk.

On the desktop, select My Computer.

Right-click on My Computer and select Manage.

Then the Computer Management window will pop up.

Select Disk Management.

Then you can see the hard drive of your computer.

The active partition is for the primary partition, and the logical partition cannot create the active partition.

Right-click on the main partition, if it is not already active partition, you can right-click to rotate.

But my C drive is already an active partition, so I don't need to turn it.

It is divided into four partitions: the main partition of the hard disk, the logical partition, the extended partition, and the active partition The main partition: In the early days of the hard disk, it did not distinguish between the primary partition, the extended partition, and the logical partition.

Due to the size of the partition table in the main bootloader, it can only be divided into four partitions. With the continuous development of technology, everyone found that four partitions were not enough, so the extended partition (the name given by the operating system to a primary partition) was derived, and the logical partition: the previous partition was called the primary partition. The primary partition is the hard disk partition that contains the necessary files and data required for the operating system to boot, and to install the system on the hard disk, the hard disk must have a primary partition. Primary partitions are numbered from 0-4, with a minimum of one and a maximum of four.

Active Partition: This is the primary partition and the system partition, and each time the system boots from the active partition of the hard disk, and loads the bootloader (NTLDR or GRUB) on the active partition

Inside the Disk Manager, the activity is not set in the first partition settings, and the active partition cannot be started.

Active BAI partition,It is the first boot partition identified by the system,If you don't set the active DAO partition,The system can't boot back,AnswerBut the current GHOST system disk is installed in that partition,Automatically set the partition to the active GeneralGeneralThe current GHOST system disc has PQ partition software,You can set the partition as active in and out of the PQ partition software,Divide the area well,For example, set C as active,Point to C area,Right click,Operation or setting, You can change that some computers can not use a mouse in the use of PQ partition software, so you can only use the keyboard, and you can use the tab key to switch operations when using the keyboard.

The active partition is generally the primary partition where the BAI operating system is activated. This is my zhi

Understand. In the DOS era, there was only one primary partition, which was located at the front of the hard disk, and now multiple main partitions can be set up to install multiple systems. Switch with software.

At the same time, only one primary partition is active, i.e., the active partition. If there are multiple hard disks and each hard disk has a primary partition and activated, you can see in the disk management in my computer right-click - management, there are multiple active partitions, one of which is written as the system, that is, the system is the operating system currently in use, and the other is the active partition but not activated (not used). Hope it helps.

2.Install two operating systems, one on the primary partition and the other on the logical partition, the active partition can only be the primary partition, and the system boot only finds the boot file of the active partition, that is, it can only boot the operating system of the main partition with the bootloader on the primary partition, and can only boot the operating system of the logical partition with the bootloader on the primary partition.

3. When installing two operating systems, one on the primary partition and the other on the logical partition, you must start the correction on the primary partition, that is, to carry out dual boot menu repair, you can write boot program files, and you can also use dual boot menu repair software.

1 Yes;

2 Correct understanding. However, multi-system booting is not affected.

The active partition is the zone from which the computer boots up, and the computer cannot be started without setting the active partition. In DOS partitions, only basic DOS partitions can be set as active partitions, and logical partitions cannot be set as active partitions. It is recommended that you set the C drive as the active partition.

Only the primary partition can be set as the active partition, and when the hard disk is divided into multiple primary partitions, any one of them can be set as the active partition.

In the list and graph views, the system, active, and bootstrap partitions are labeled as System, Active, or Boot, respectively.

You can't mark a logical drive as active.

Only partitions on the Primary Boot Record (MBR) disk can be marked as active.

A computer can have only one active partition per disk.

Changing or deleting the active partition can cause the computer to fail to start.

The partition names that are commonly used to contain boot and operating system files are the system and boot partitions, respectively.

The system partition must be the primary partition that has been marked as active for boot and must be on the disk that the computer accesses when the system is booted. There can only be one active system partition on the same disk at a time. You can have multiple basic disks at the same time, each with an active partition.

However, you can only start your computer from one of the specified disks. If you need to use a different operating system, you must mark its system partition as active before restarting your computer.

You can only create primary partitions, extended partitions, and logical drives on basic disks. If the computer is also running MS-DOS, Windows 95, Windows 98, Windows Millennium Edition, Windows NT, or Windows XP Home Edition, you should create a base volume instead of a dynamic volume.

On a primary boot record (MBR) disk, you can create up to four primary partitions, or three primary partitions plus an extended partition.
