2. What makes a disc bootable? A disc is considered bootable when it contains specific information and files that allow it to initiate the startup process of a computer. This typically refers to a CD, DVD, or USB drive that has been prepared with the necessary boot sector and system files. Here's a breakdown of the key elements that make a disc bootable: 1. **Boot Sector**: The boot sector, also known as the Master Boot Record (MBR) on hard disks, contains the first code executed by the computer's BIOS when it starts up. This code is responsible for loading the operating system or boot loader from the disc. 2. **Boot Loader**: A boot loader is a small program that manages the process of loading the operating system into memory. It initializes the necessary hardware, reads the operating system image from the disc, and transfers control to it. 3. **Operating System Files**: For a disc to be bootable, it must have the necessary files of an operating system, such as Windows, Linux, or macOS. These files include system libraries, drivers, and core components required to start the OS. 4. **Media Type**: The disc needs to be of a type that can hold bootable data, like a CD-R, DVD-R, or a USB drive formatted with a file system like FAT32 or NTFS. 5. **Bootable Image**: In the case of creating a bootable disc from an ISO image, the image must be properly burned or written to the disc using software like Rufus, ImgBurn, or Brasero. This ensures that the bootable information is correctly preserved. 6. **BIOS/UEFI Settings**: The computer's BIOS or UEFI firmware should be configured to boot from the correct device, such as the optical drive or USB port, during the startup process. By ensuring these components are in place, a disc can be made bootable, allowing it to start a computer and potentially install or recover an operating system, run diagnostic tools, or perform other specialized tasks.

When you create a bootable CD or USB drive, the storage device is formatted with a partition known as the MBR (Master Boot Record). This MBR is distinct from the partition style MBR; it refers to the boot sector of a hard disk. Regardless of whether your partition style is GPT (GUID Partition Table), as long as it serves as the boot disk, it will have an MBR partition. When you use your bootable CD, the BIOS loads and runs from the MBR boot sector.
