They are the files that your computer call on to start up, or "boot." without these, the computer cannot function properly.
Start Menu
Upon booting up or rebooting a computer, the system looks for configuration files which tells the computer how to load and what to load. The Windows registry in the System Ini files contain a list of of all the user's settings/preferences and a list of all the program it will need to load on start up. These files can be modified to change settings, what programs to load on start up and many other settings and preference.
A boot sector virus is a computer virus that puts itself in the boot sector of a computer. The boot sector is the partition on the disk drive that contains all of the programs and files necessary for the computer to start up. This ensures that the virus will be executed once the computer is turned on.
Depending on the computer type the start up files can differ, but generally the computer runs the bios files first, after that it will load the core components of the operating system and then run further no core parts as needed
Operating system is obviously resides in computer memory which is hard disk. But the main (booting) files are loaded into ROM by bootstrap loader at the time of start of the computer. Have you ever seen your C drive (or the drive which is for system, program files). This drive is on hard disk ... so OPERATING SYSTEM PLACED MAINLY ON HARD DISK...
You can start a computer with either a CD-ROM disk or a floppy disk. This is commonly used in troubleshooting when a system will not start up or what's called "boot-up." In those situations the computer is changed in BIOS to boot up from either the CD-ROM or floppy disk and the files necessary to start the computer are on those files..hope this helps.
Basic Input Output System (BIOS)
An ini file is most commonly found in video game data files or in the files of your operating system. Ini files are used to save and manually modify the basic settings that you computer or video game loads into on start up.
When the computer start all the essential files, to start the operating system load from disk to the memory.Basically the bootstrap program is loaded into the read only memory(ROM) which enables while the computer start.
