Bootable Installer Preparation
Embedded Files
The software installer package of an operating system from the market is usually inside a CD or DVD. There are times when we come across situations where there is no CD of DVD drive in a computer so there is no way we can use that CD/DVD to install or reinstall that operating system.
Having a bootable version of Windows on a DVD and USB drive can be very useful in times when we need to install an operating system. A DVD installer can be used whenever the version of BIOS of the computer doesn't allow for USB installers. A USB installer can also be used whenever there is no available CD or DVD drive in a computer.
ISO Image File - A file with an .iso file extension is a virtual copy of a CD or DVD with the same file structure and the same data. ISO copies referred to as "images" of the original. Therefore, the ISO is a perfect copy of what would be an original Windows CD or DVD.
Bootable Device - A bootable device is a kind of storage hardware, such as a hard drive, USB flash drive, CD, or DVD which contains necessary boot files and drivers for loading the operating system.
Bootable Installation Package - The bootable package contains a disk image that is identical to the boxed product that you would purchase at any software retailer. This image may be burned directly to physical media to produce a bootable installation DVD. Once copied to physical media, this package may be used to install an Operating System on any compatible hardware, with or without an existing Operating System installed.
