A system installer is the software that is used to set up and install an operating system onto a device. Windows Setup is the system installer of Microsoft Windows. Examples of Linux system installers: Anaconda: used by CentOS, Fedora; Calamares: used by multiple Linux distributions (incl. some Ubuntu flavors, Debian, and derivates)
Multi-booting is also useful in situations where different software requires different operating systems. A multi-boot configuration allows a user to use all of their software on one computer. This is often accomplished by using a boot loader such as NTLDR, LILO, or GRUB which can boot more than one operating system.
Designed to be simpler and faster than previous installation methods, it analyses the system's hardware and software for compatibility with Windows 8, allows the user to purchase, download, and install the operating system, and migrate files and settings from the previous Windows installation in the case of a clean install.
Some package managers, such as Debian's dpkg, allow configuration during installation. In other situations, it is desirable to install packages with the default configuration and then overwrite this configuration, for instance, in headless installations to a large number of computers. This kind of pre-configured installation is also supported ...
When operating systems came to be distributed on compact discs, either a boot floppy or the CD itself would boot specifically, and only, to install onto a hard drive. Early examples of operating systems which could be booted directly from CD-ROM are the FM Towns OS, [3] and the Desktop-VMS distribution of VMS, both of which were first released ...
JumpStart is used to manage operating system installation in many Information technology environments (corporate and otherwise) where Solaris operating system computers are widely used. It can provide easier installation (minor setup on central server, then one command on an installation "client" system to start it installing).
CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system's DOS BIOS (typically residing in IBMBIO.COM or IO.SYS) during boot. CONFIG.SYS was introduced with DOS 2.0. [nb 1]
RIS is used to create installation images of operating systems or computer configurations, which can be used to demonstrate the installation process to users whose machines have been granted access to the RIS server. This eliminates the need to use a CD-ROM for installing an operating system. [1]
