to Make a Bootable CD-R
"El Torito" standard developed by Phoenix Technologies and IBM describes
how to create bootable CD-ROMs for PCs. The bootable CD format creates
a bootable image of an ISO 9660 file that is an exact representation
of a floppy or hard drive from that you can boot your PC.
The recent lower cost of CD-writers and CD-R's makes bootable CD-R
an attractive alternative to tape backup unit. Making a bootable
CD-R is a solution to stop the so called "computer rage" when you
need to reinstall the operating system.
your PC to boot from a CD-ROM, you will need either a SCSI controller
equipped with a "new" controller BIOS allowing booting from CD-ROM
and a SCSI CD-ROM drive connected to that controller, or an IDE/ATAPI
CD-ROM drive and a PC BIOS allowing the boot from CD-ROM.
you make a bootable CD-R to reinstall your hard drive, you should
backup your data files first and setup all the stuff you need, including
drivers (video drivers, network drivers, etc.), backup software,
and favorite programs.
and Software Required to Make a Bootable CD-R
will need a CD-ROM reader, a CD-R writer and CD-R writing software
such as Adaptec Easy CD Creator Deluxe, Easy CD Creator 4, CeQuadrat
WinOnCD, or Nero-Burning Rom.
make an ISO 9660 image file of your hard drive, you may use software
such as Power Quest's Drive Image, Ghosts' Ghost40a, Nortons' Diskedit.exe,
Procedure in Making a Bootable CD-R
- Install the
CD-R writer as "master" and the CD-ROM as "slave" in your computer.
- If you want
your bootable CD-R to work with other computers that may contain
other cd-rom drives, use the generic Microsoft Atapi_cd.sys Driver,
instead of a device specific cd-rom drivers.
- Make a bootable
"diskette" and install all the drivers you require. The config.sys
file should contain statements such as Device=Atapi_cd.sys. (Or
make a copy of the Windows OS boot disk that contains all the
tools required such as fdisk, format.com etc.)
- Install the
software capable of making an image of your hard drive. You should
reserve enough space on another hard drive partition to store
the image. Select the image file you made as the source of boot
image data. (Or if your bootable logical drive is smaller than
650MB, you may select it as the source of boot image data.)
- Run the CD-R
writing software capable of writing a bootable CD-R. For specific
procedures in burning the bootable CD-R, refer to the operating
manual of the CD-R writing software. (If the Boot dialog box of
your CD-R writing software has a field for "Load segment
of sectors", keep the default value as this is the address
used by most operating systems.
- Change your
BIOS on bootup to recognize the CD-ROM, C, A boot sequence to
test the CD-R you have made.
