Can the system be mounted on an extended logical partition?

A physical partition is LVM's smallest unit of disk space allocation. A physical partition is a disk space of the same size on a physical volume.

The size of a physical partition is specified when a physical volume joins a volume group. A physical volume inherits the size of the physical partition of the volume group. This size is determined when the volume group is created.

Understand logical volumes.

Physical partitions make up logical partitions, and a logical volume is a collection of multiple logical partitions within a volume group. Logical volumes are scalable and can span multiple physical volumes within a volume group, and for added reliability, a logical volume can have one to three physical copies.

Logical volumes define the allocation of disk space down to the physical partition (minimum 1 megabyte, megabyte is 2 to the 20th power), and good space management is done by high-level software such as virtual memory managers or file systems. These operations may be required after a logical volume has been established or expanded, but before it is copied or deleted.

Both primary and extended partitions are logical partitions.

Only the one with the system is the primary partition, and the rest is the extended partition.

Of course, if you have a dual system, you can install it on the expansion partition.

The master and slave disks can be seen in the following connections.

Common XP Win7 is fine. For example: D disk, E disk, F disk, etc.

But the bootloader is still installed on the C drive. If the C drive is broken or formatted, the installed system will not boot.

To install the system to another partition, use the installed version of the system disk. The ghost system disk can only be installed on the C drive.

XP can. Win7 can.

Mac cannot.

Linux can.

1. The operating system does not necessarily have to be installed on the primary partition, but your hard disk must have at least one primary partition.

2. It can be installed in the logical partition, but the boot file of the system is still automatically installed on the active partition, which is automatically set by the system when you install the system, without manual intervention.

3. It can be used, and there is not much difference between it and the main partition installed in the primary partition, but when backing up the system image, the primary partition should be backed up at the same time, if the boot information is lost due to the change of the primary partition, the primary partition should also be restored when the image is restored, otherwise the system will not be able to boot.

A logical partition is a contiguous area on a hard disk, except that each primary partition can only be divided into one drive, and each primary partition has its own independent boot block, which can be set as the boot area with fdisk. A hard disk can have up to 4 primary partitions, while an extended partition can be divided into multiple logical drives. These logical drives do not have a separate boot block and cannot be set as the boot area with fdisk.

Both the primary partition and the extended partition are DOS partitions.

There are three types of hard disk partitions: primary disk partitions, extended disk partitions, and logical partitions. [1]

A hard disk has at least 1 main partition and a maximum of 4 partitions, and an extended partition can have no partition at most. The total number of primary partitions + extended partitions cannot exceed 4. There can be several logical partitions. [1]

The active main partition is the boot partition of the hard disk, which is independent and the first partition of the hard disk, which is the C drive if it is normal. [1]

After the main partition is separated, the rest can be divided into extended partitions, usually all the remaining parts are divided into extended partitions, or not all of them, and the remaining parts are wasted. [1]

However, the extended partition cannot be used directly, it is used in the way of logical partitioning, so the extended partition can be divided into several logical partitions. Their relationship is an inclusive relationship, and all logical partitions are part of the extended partition.

The primary partition (active partition) can store boot information, and the boot information must be read from the primary partition when the operating system is booted.

Partitions other than the primary partition become extended partitions.

Extended partitions can be divided into multiple logical partitions.

This is an easy way to understand

You can divide all partitions into primary partitions.

Primary partition: The primary partition is a relatively simple partition, usually located in the front area of the hard disk, forming a logical C disk. The main bootloader is part of it, and this section of the program is mainly used to check the correctness of the hard disk partition, and determine the active partition, which is responsible for handing over the boot power to the DOS or other operating system of the active partition.

If this section of the program is corrupted, it will not be able to boot from the hard disk, but the hard disk can be read and written from the soft or optical area.

Logic and Extensions:

The concepts of extended partitions and logical partitions are complex, which may cause confusion between hard disk partitions and logical disks. The fourth byte of the partition table is the partition type value, and the normal bootable basic DOS partition value greater than 32MB is 06, and the extended DOS partition value is 05. If you change the basic DOS partition type to 05, the system cannot be started and the data in it cannot be read or written.

Active partition: The active partition is the boot partition of the computer, and the boot files of the operating system are installed in this partition, which is generally the C drive by default. When the system is booted, the operating system on the active partition performs a process called drive imaging, which assigns drive names to the primary partition and logical drives.

All primary partitions are imaged first, while logical drives are designated with subsequent letters.

A hard disk can be divided into up to four primary partitions, and your situation above depends on how many primary partitions you have. If you follow the traditional partitioning method, a primary partition, the remaining space is divided into the extended partition, and then the extended partition is divided into logical partitions, so that your disks are as follows.

C, the main partition, the system is in the C drive, generally the C drive is set as the active partition, so the C drive is the active partition.

The whole of defg is the extension partition, where d, e, f, and g are the four logical partitions.

It's all about copying the answers! Dizzy!!!

Let's give you a graphic example.

A hard drive is like a house.

Each room in it is a partition, no matter what zone it is.

There is generally at least one living room, and people from outside always come in first. This is the primary partition, and only here is the boot computer into.

The other rooms are grouped together and are collectively referred to as extended partitions. That is to say, except for the living room, the other rooms are called bedrooms together, which is the extended partition.

Your family can't sleep in one bedroom, so if you have three bedrooms, then each bedroom is a logical partition.

So you get it.

Seeing that I worked hard for half a day is better than those who copy the answers everywhere.

Again despise!

A maximum of 4 partitions can be written to the MBR record of a hard disk. So with MBR you can only divide up to 4 partitions.

When you want to manage multiple partitions, you often use one primary partition and one extended partition. Extended partitions cannot be used directly, they must be divided within them.

Logical partitioning. to be used. For example, the usual partition form is: C drive is the main partition, the remaining space is the expansion partition, and the disk partitions such as D, E, F, G, and H belong to.

Logical partitions, which are contained within the extended partition.

Agree with the above.

Disk = primary partition + extended partition (extended partition can be divided into n logical partitions) The general hard disk is four to five zones.

System partition + work partition + game partition + video partition.

If necessary, you can divide yourself into several districts.
