The primary partition thus subdivided is the extended partition; the sub-partitions are logical partitions. They behave like primary partitions, but are created differently. There is no speed difference between them. … The disk as a whole and each primary partition has a boot sector.
What is the difference between primary partition and extended partition?
Primary partition is a bootable partition and it contains the operating system/s of the computer, while extended partition is a partition that is not bootable. Extended partition typically contains multiple logical partitions and it is used to store data.
What is the use of extended partition in Linux?
An extended partition is a partition that can be divided into additional logical drives. Unlike a primary partition, you don’t need to assign it a drive letter and install a file system. Instead, you can use the operating system to create an additional number of logical drives within the extended partition.
What is a primary partition in Linux?
A primary partition is any of the four possible first-level partitions into which a hard disk drive (HDD) on an IBM-compatible personal computer can be divided. … An active partition is one that contains the operating system that a computer attempts to load into memory by default when it is started or restarted.
What is an extended partition?
An extended partition is a special type of partition that can hold multiple logical partitions. It’s is like a container/wrapper of all logical partitions. Inside an extended partition you can create many logical partitions (this solves the maximum number of drives limitation).
Is logical partition better than primary?
We can install OS and save our data on any of partitions kind (primary/logical), but the only difference is that some operating systems (namely Windows) are unable to boot from logical partitions. An active partition is based on primary partition.
Can logical drive merge with primary partition?
So, to merge logical drive into primary partition, it is necessary to delete all logical drives and then extended partition to make unallocated space. … Now the free space becomes unallocated space, which can be used to extend the adjacent primary partition.

What is the partition in Linux?
Introduction. Creating disk partitions enables you to split your hard drive into multiple sections that act independently. In Linux, users must structure storage devices (USB and hard drives) before using them. Partitioning is also useful when you are installing multiple operating systems on a single machine.
What are the two main partitions for Linux?
There are two kinds of major partitions on a Linux system:
- data partition: normal Linux system data, including the root partition containing all the data to start up and run the system; and.
- swap partition: expansion of the computer’s physical memory, extra memory on hard disk.
What is meant by primary partition?
Primary Partition is the hard disk partition where both Windows OS and other data can be stored, and it is the only partition that can be set active. can be set active for BIOS to locate, and the primary partition saving boot files must be set active.
What is primary and logical partition in Linux?
When such partitions are created on a such derive, they are called “primary”. … In layman’s words: when a partition is created simply on a drive (in a MBR partition-scheme), it is called “primary”, when it is created within an extended partition, it is called “logical”.

After creating an extended partition you need to create a logical partition in it. Then you should be able to create a file system in it or use dd to copy the image back.
Can I delete extended partition?
You cannot delete the extended partition because you may only select one logical partition at a time and this partition contains several. Thus, you need to delete all the logical partitions first, then delete the extended partition.
How many extended partitions can you have?
There is no speed difference between them. By using an extended partition you can now have up to 15 partitions per disk. The partition structure of a hard disk might look like that in Figure 5-2. The disk is divided into three primary partitions, the second of which is divided into two logical partitions.
