Booting from CD-ROM
When installing Windows98 or
Windows Millenium, there is first a challenge :
- how to start the SETUP program on the installation CD-ROM ?
that requires, that some kind of operating system is already
installed on the system,
which is able to access the CD-ROM and able to start the
(often, a DOS-boot floppy disk is used
to install a minimum DOS-system, just loading the CD-ROM-driver
and MSCDEX.EXE, allowing to run SETUP ).
Starting with Windows NT4, then with Windows2000 and now with
the installation CD-ROM is bootable, allowing to make an
installation without having
first to install another operating system, just to get the CD-ROM
drive to work.
All modern PC-systems , manufactured in the last years, support
this feature, but it may be
required to configure this feature (a previous owner of your
system may have deactivated
this feature or may have changed the boot priority sequence ) :
start/restart your system and
check the boot-screen :
look for a message similar to : "Press ... to enter
SETUP", on most PC's it will be the DEL-key.
pressing that key will enter your PC BIOS setup :
Look for a menu-option "Boot". If it is not listed,
check the other screens of the BIOS setup,
it is often part of an advanced setup page.
The screen should show the Boot-sequence (in
this example, the system will first try to
boot from the Removable device = Floppy disk, if it ca not find a
bootable floppy, it will try to boot from Harddisk,
and as long as a harddisk is installed, it will either boot from
the harddisk or report a boot problem, if there is not yet
an operating system installed on the harddisk. It will NOT try to
boot from the CD-ROM) and some instructions
on how to change the boot-sequence (in this
example : using the "+" and "-" keys ).
Follow these instructions to have the first to try to boot from
CD-ROM before trying to
boot from harddisk :
Then store this new configuration (in this example via : F10).
You can now insert your bootable CD-ROM and install it by booting
from the CD-ROM
installation of Windows XP ).
