INSTALLATION METHOD-Creating MBR recovery Step1

You have two choices, 
1.a single Operating System (OS) 
2. a multi-boot system


Single operating system(os):-
                  We can install single os ina system thats only LINUX -that will never cause any fault in booting most probably(than mulit boot)


Multi-boot system:-
                Installing dual or more than that in a single hard disk - Like  Windows,Linux,Mac or Win xp ,Win 98,redhat(linux),Win xp.....
                    On Installing mulit os Boot loader will ask at the time of boot - which one want to choose it from ,we can select it from that prompt
                      on installing multi -boot cause override problems - its wiser to make a recovery CD as a Administrator to recover from it 






As i dont know about creating this MBR disk i just copied this from several sites by referral :-) 
and iam trying to do it after i finished and tested i will strongly recommend it until then dont try this plzzzzzzzz






Okey lets move on to the uestion HOW TO MAKE RECOVERY CD in MS/WINDOWS


There are three steps :
1.Make a wise backup of files that is important in ur system - even its better  to make it at the time of updating that files 
2.Make a Dos boot floppy to restore MBR if its gete corrupted
3.Create Dos/Windows reovery disks for Dos/Windows partition (if dual boot is required )


Oops i forget to tell about MBR
yup MBR is MASTER BOOT RECORD is the  information in the first sector of any hard disk or diskette that identifies how and where an operating system is located so that it can be boot (loaded) into computers main storage or RAM 


simply saying MBR contains table of records of boot option of all OS in which user an choose any one of them and then it will search in that table for that particular partition and load that in to RAM for access.


Okey again move on to the Steps to create a wise recovery diskette fo windows :


Dos recovery disk:
Note: These steps are for users who have MS-DOS installed on the computer. If you have any version of Windows follow the below steps for your version of Windows.

To create a MS-DOS diskette, begin by getting to the DOS directory by typing:

cd/dos

NOTE: When making a boot disk, if you are running "Stacker" or some kind of a DoubleSpace or drive swapper program, this could not work

Once you are in DOS and at the correct directory as instructed in the above sections by operating system, you are ready to create your bootable diskette. Insert a diskette that does not contain any information (it will be erased).

At the prompt, if you have MS-DOS 6.2 / Windows 3.x / Windows 95 / Windows 98, type:

FORMAT A:/S

If you have MS-DOS 5.0 type using double density 5.25" diskettes type:

FORMAT A: /360 /S

If you have MS- DOS 3.11 through 4.0 using double density 5.25" diskettes, type:

FORMAT A: /4 /S

Once the diskette has been formatted and the system has been transferred, you should be returned to your original directory. In this directory, type:

copy format*.* a: [PRESS ENTER]
copy fdisk*.* a: [PRESS ENTER]
copy mscdex*.* a: [PRESS ENTER]
copy sys*.* a: [PRESS ENTER]
copy edit*.* a: [PRESS ENTER]
copy qbasic*.* a: [PRESS ENTER] (Win 95/98 users skip this line)
copy debug*.* a: [PRESS ENTER]
copy himem*.* a: [PRESS ENTER]
copy emm386*.* a: [PRESS ENTER]

If you are planning to use this diskette as a diskette to load games or you feel that you need mouse support, you will need to copy the mouse driver onto the boot diskette. The MS-DOS mouse driver is generally mouse.com / mouse.sys. Locate this file and copy it to your bootable diskette.

Once you have copied the above files, create an  autoexec.bat and config.sys

About the autoexec and config

The autoexec.bat and the config.sys were files created for MS-DOS and Windows 3.x as an easy solution of loading the files required for various devices as well as the operating system to properly run. These files are required for later revisions of MS-DOS and Windows 3.x to load. Because Microsoft is trying to steer away from MS-DOS, these files are not required for Windows 95, Windows 98, Windows NT, Windows ME, Windows 2000, Windows XP, or later operating systems. However, in some cases it may still be necessary for users to edit or configure these files.

How to edit the files

The auotexec.bat and the config.sys are most commonly edited by the MS-DOScommand file Edit. To edit these files, type edit c:\autoexec.bat to edit the autoexec.bat file, or edit c:\config.sys to edit the config.sys file. If the mouse drivers are not loaded properly you will not have the capability of navigating the mouse.

If you have Windows 95, Windows 98, or later versions of Windows it is recommended that you use the sysedit command; to run this program, click Start / Run and type sysedit.

Remarking information

Remarking lines within the autoexec.bat or the config.sys allows you to temporarily or permanently prevent a line from loading each time you boot the computer. This is done by placing "REM " in front of the line you wish to skip.

If you are encountering issues with a line in the autoexec.bat it is highly recommended that you remark the line instead of removing it. This will prevent issues from arising if the line needs to be placed back into the autoexec.bat.

Getting additional memory

The below commands will help allow your computer to load programs into memory more efficiently allowing you to have more memory for MS-DOS programs / games.

Ensure you have the below three lines at the beginning of your config.sys file.

DEVICE=C:\Windows\HIMEM.SYS
DOS=HIGH,UMB
DEVICE=C:\Windows\EMM386.EXE NOEMS

By placing the DOS=HIGH,UMB on the second line, this can, in some cases, save memory because it is loading DOS into upper memory before loading the memory manager. Additionally, the first and third lines cannot be loaded into high memory because these lines are the memory managers.

Load all your devices in your config.sys and autoexec.bat into high memory.

Autoexec.bat layout

Below is an example of what an autoexec may look like:

@echo off
SET SOUND=C:\PROGRA~1\CREATIVE\CTSND
SET BLASTER=A220 I5 D1 H5 P330 E620 T6
SET PATH=C:\Windows;C:\
LH C:\Windows\COMMAND\MSCDEX.EXE /D:123
SET PATH=C:\Windows;C:\
LH C:\Windows\COMMAND\MSCDEX.EXE /D:123

Get to the floppy drive by typing A:, once at the floppy drive, type:

copy con autoexec.bat [PRESS ENTER]
@echo off [PRESS ENTER]
LH A:\MSCDEX.EXE /D:CDROM [PRESS ENTER] (this line is used for your CD-ROM drive).
LH A:\MOUSE.* [PRESS ENTER] (skip line if you did not copy mouse file, the * is either sys / com).

Press and hold CTRL + Z - this should return ^Z. Once this is displayed, press enter to copy the file.

copy con config.sys [PRESS ENTER]
device=a:\himem.sys
dos=high,umb
device=a:\emm386.exe noems
files=30
buffers=20
devicehigh=a:\oakcdrom.sys /d:CDROM (this line is used for your CD-ROM drive).

Press and hold CTRL + Z - this should return ^Z. Once this is displayed, press enter to copy the file.

Congratulations, after completing the above steps you should now have a bootable floppy diskette.



yup  now let i inform how to use this  disk as i know that :p


First boot the system with Rescue cd inside adn then enter the following commands in shell

ter the following shell command:

• DOS/Win9X:

  A:\>FDISK /MBR C:
  

• Win 2000/NT: (boot from CD and enter "Recovery Console")

  fixmbr
  

• Win XP: (boot from CD and enter "Recovery Console")

  bootcfg /rebuild
  

   yes thats all urs MBR will be normal back to action
  
  
  on next post u can see the installation method
