Some notes about boot process on a pc using windows as the o/s and the proper steps in sequence.

Steps: 1. computer BIOS runs self-tests 2. if no problems, BIOS tries to boot an operating system from a drive. Older computers usually try a: drive first, c: drive second. Newer computers have a BIOS setting to tell BIOS where to look first, usually c: 3. BIOS looks for bootup files (usually on drive c: 4. most common bootup files are the Microsoft bootup files: io.sys, msdos.sys, and command.com 5. next, DOS looks for config.sys file and loads drivers line by line. 6. next, DOS looks for autoexec.bat file and executes DOS commands or runs given programs line by line This is a quickie version of the bootup process. Someone else may want to give the long version.

CONFIG.SYS, COMMAND.COM, and AUTOEXEC.BAT are only loaded if you are using the MS-DOS (and 85% compatibles) kernel -- IO.SYS --. Actually, COMMAND.COM loads AUTOEXEC.BAT, as such a file cannot be loaded without a command interpreter. And if a different SHELL= line is specified in CONFIG.SYS, then neither COMMAND.COM nor AUTOEXEC.BAT load...and also only the MS-DOS (and once again, 85% compatibles) kernel loads DRVSPACE.BIN and DBLSPACE.BIN into memory.

Naw - yar dun well Reconsider yar boot order with an OS installed - yar right if the drive is formated but no OS If an OS is installed (includes 9x as well as DOS) the boot order is io.sys msdos.sys config.sys command.com autoexec.bat user batch files

Also BIOS loads the boot sector (or the MBR which then loads the boot sector) from disk, not the "bootup files". The boot sector code attempts to load the "bootup files". And by the way Rajan a please would have been nice.

Step 1 Turn on your computer. 2 Watch your monitor while waiting. 3 Voila! Windows appears! or if you don't understand... 1 Take your computer, monitor, keyboard, and all related accessories and carry to the rooftop. 2 Throw the computer off the rooftop, then the monitor, keyboard, etc.. 3 Take a deep breath, jump off the rooftop and land head first(try to aim for your computer).

Explain in detail the steps that occur during yhe boot process on a personal computer using Windows Operating System(i.g window 2000)
