Yes, it it optional, but often highly recommended, to make sure the image will behave as expected, or even to run at all.

No.
There is no "the" installation program for Linux. Each distribution has its own (more or less), and it's generally referred to as "the installer" unless they've given it a more specific name.
There aren't any errors specific to Linux. Linux has the same types of bugs found in every other operating system.
There is no "the startup file" in Linux; depending on the type of system, there may not be any files at all. The Linux boot process has a number of steps, many of which are optional or have alternative implementations.
Without knowing what errors you are receiving, and what you have already tried, it would be impossible to suggest an appropriate course of action.
RT Linux is a specific distribution of Linux, as is Fedora. You can install RT Linux over Fedora, but RT Linux isn't a program you install in a Fedora installation, but an entirely different installation altogether (and meant for different things; RT Linux is meant for specialty devices where the machine needs to manage devices and calculations in Real-time whereas Fedora is more a desktop/server distribution.)
One can find instructions on how to run e2sck Linux by checking the Linux website directly. There are clear instructions on how to run all Linux programs.
You have to use so called SMB server (usually it's included in each Linux installation) which allows to communicate Linux with windows.
It doesn't. ISO is a disk image format that is often used to distribute Linux and other CD images.
Most Linux distributions are available free of charge, so they do not require q product key to install.
