How to Create Ms-Dos BootCD ?

How to Create Ms-Dos BootCD (Hiren's Bootable CD)?

Tools Used:
bfi.exe (Build Floppy Image - to create bootable image from files)
mkisofs.exe (a tool to create/build the CDRom ISO image file)
build-iso.cmd (batch file to create floppy and iso image)
We will need some files from Windows ME or Windows XP startup disk
io.sys (Dos Input Output System file)
msdos.sys (Dos system file)
command.com (MS-Dos mode command line interpreter)
himem.sys (An extended memory manager that is included with DOS and Windows)
mscdex.exe (Microsoft CD-Rom Extension)
oakcdrom.sys (Generic CD-Rom driver, work with the most of all IDE CD-ROM drives)
xmsdsk.exe (Adjustable XMS RAMdisk Driver - Freeware)
ctmouse.exe (Mouse Driver For Dos - also works on USB Mouse - Freeware) or mouse.com
All the necessary files are included in bootcd.zip Download (468KB)

AUTOEXEC.BAT

@ECHO OFF
MSCDEX.EXE /D:CDDRIVER /L:X
XMSDSK.EXE 51200 R: /t /y
CTMOUSE.EXE
PATH=A:\;R:\
GOTO %CONFIG%

:TESTDISK
COPY X:\TESTDISK\*.* R:
R:\TESTDISK.EXE
GOTO DOS

:GHOST
COPY X:\GHOST\GHOST.EXE R:
R:\GHOST.EXE
GOTO DOS

:NTFS
COPY X:\NTFS\*.* R:
R:\NTFS4DOS.EXE
GOTO DOS

:RPM
COPY X:\RPM\*.* R:
R:\RPM.EXE
GOTO DOS

:DOS
ECHO  X: CD DRIVE
ECHO  R: RAM DRIVE

CONFIG.SYS

[MENU]
menuitem=DOS, Dos
menuitem=TESTDISK, TestDisk
menuitem=GHOST, Ghost
menuitem=NTFS, Ntfs
menuitem=RPM, Partition Manager

[DOS]
DEVICE=OAKCDROM.SYS /D:CDDRIVER /L:X

[TESTDISK]
include=DOS

[GHOST]
include=DOS

[NTFS]
include=DOS

[RPM]
include=DOS

[COMMON]
LASTDRIVE=Z

You can add your favorite Programs in the bootcd,
All you need to do is Edit autoexec.bat and config.sys and add all the required files in the folder and double click on build-iso and you are ready to burn bootcd.iso
Example: You want to add Mcafee Antivirus in the bootcd, all you do is create a folder MCAFEE in the folder CD
and add a line in config.sys menu
menuitem=MCAFEE, McAfee Antivirus

add two more lines in config.sys
[MCAFEE]
include=DOS

and add 4 lines in autoexec.bat
:MCAFEE
COPY X:\MCAFEE\*.* R:
R:\scanpm.exe /adl /all /clean
GOTO DOS
when you start your computer with this bootcd, you will get to menu where you can choose which program you want to run. In this example we will create 50Mb Ram Disk (You will have Minimum of 64Mb Memory)

Microsoft Windows Startup Menu
‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗‗

    1. Dos
    2. TestDisk
    3. Ghost
    4. Ntfs
    5. Partition Manager
    6. McAfee Antivirus Enter a choice: 1

You can easily create bootable cd,
all you have to do is add few lines in autoexec.bat and config.sys
and copy files in CD folder and double click on build-iso.cmd
and it creates a iso file BootCD.iso
You can add as many items in the list but you are limited to 9 per screen
to add more items simply add submenu=MORE, More... (under [MENU] block)
and add [MORE] in config.sys and you can add more menuitem there

Formatting an HDD, when FDISK won't work

This was originally posted by andro11meda in Hardware and Networking Support. It worked so well for me on a problem-computer that I was working on that I had to post it in tutorials. Thanks andro11meda!!

***
This is my favorite way to wipe it clean:

CAUTION: This debug script is for advanced users only. Its Purpose is to remove all formatting and partitioning information from your hard disk when FDISK is unable to do so. THIS WILL REMOVE ALL DATA AND PROGRAMS FORM THE DRIVE.

1. Create a MSDOS bood disk with Debug

2. At DOS command prompt type the following: Debug[Enter] (Where enter is to press the enter key once)

-F 200 L1000 0 [Enter]
-A CS:100 [Enter]
xxxx:0100 MOV AX,301 [Enter]
xxxx:0103 MOV BX,200 [Enter]
xxxx:0106 MOV CX,1 [Enter]
xxxx:0109 MOV DX,80 [Enter]

NOTE: ( --- "80" for hd0, "81" for hd1)

xxxx:010c INT 13 [Enter]
xxxx: 010e INT 20 [Enter]
xxxx: 0110 [Enter]

-G [Enter]
"Program terminated normally"

3. Turn off the computer. On the next startup the hard drive will need to be partitioned and formatted.
