  Booting is the process of starting or resetting the computer when the user turns the system on. The process includes getting both the   hardware   and   software   ready and running. The booting process is of two types: Cold booting:   The process happening when we first turn on the computer. Also called as hard boot, this happens when user completely cuts the power supply to the system. Warm booting  is the process happening when we reset the computer. In this process, the user restarts the system via operating system. During the process of booting, the computer loads the operating system to its memory or RAM and prepares it for use. During initialization, the system switches on the BIOS and loads it onto the ROM. BIOS stores the first instruction, which is the command to perform the power-on self-test (POST). Under POST, the system checks the BIOS chip and CMOS RAM. If the POST detects no battery failure, it continues to start other parts of the CP...

  Hard Disk Partitions refers to the creation of  logical drives  for effective memory management and a partition is the logical drive for storing the data. Hidden partition created on a drive can hide the data. The inter-partition gap is the space between the primary partition and the secondary partition. If the inter-partition drive contains the hidden data, use disk editor utilities like Disk Editor to change the information in the partition table. Doing so will remove all the references to the hidden partition, which have been hiding it from the operating system. Another way of hiding the data is to place the  digital evidence  at the end of the disk by declaring a smaller number of bytes than the actual size of the drive. Disk Editor allows  investigator  to access these hidden or vacant areas of the disk. The partitions are of two types: Primary partition:  it is the drive that holds the information regarding the operating system, system are...
