5. WHAT IS IT!
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 or DVD drive in a
computer so there is no way we can use
that CD/DVD to install or re-install that
operating system.

6. WHAT IS IT!
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.

7. 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 are
referred to as "images" of the original.
Therefore, the ISO is a perfect copy of what
would be on an original Windows CD or DVD.

8. 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.

9. Bootable Installation Package
The bootable installation 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.
