MBR , VBR and Extended Partition

MBR - Master Boot Record carries the instructions to locate active partition and initiate VBR activity

VBR - Volume Boot Record - Contains the Instructions to LOAD the OS

Extended partition:

Windows Supports Only 4 Primary partitions (A dark blue Strip) excluding created by Linux.

The rest of the Disk is Partition in a way as Partition inside Partition.

If you have 80gB Space Remaining Unallocated.

Then the full 80gB is created a Single Partition with required file System(Florescent green Strip) and again in turn, they can be partition within the Extended Partition called LOGICAL PARTITION (Light Blue Strip).

That means

Only one partition is there but logically it divided in to many partitions.
