What is the Booting Process?

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 …

Hard Disk Partitions

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 …
