I want to make my laptop boot from its CD-ROM drive, but,
the system was once configured for dual boot, and always
goes to the hard-drive, even when F2 tells it to boot form
the CD-ROM. What can I do to get rid of the dual boot menu,
to get it to boot from the CD-ROM drive?

Check that CDROM drive is working, Dual Boot does not effect Boot Device
priority. Boot manager is on HD, it should be looking at CDROM first. What
CD are you trying tp boot from? Re you sure it is clean and readable?

Hi there
What kind of dual boot: 2 windows OS or Windows and Linux or something
else?
Actually it should work if you tell it in bios to boot from CD first.
Check your CD if it is bootable.
 
I have already tried all of the obvious things what I need
is a way to remove the second OS from the MBR.

If you see the dual boot menu, that means the computer has already
booted from the hard drive. The problem has to be tackled earlier in
bios setup.

You firstly require to get into the bios. At startup press 'del' or
whatever the key is for your machine to access the bios. Then change
the boot order to put the 'cd drive' as the first device. Save and
exit (usually F10).

Put you WINXP CD in the drive and reboot. When asked select 'Repair'
(press R) when in the repair mode at the prompt enter 'fixmbr'. See
www.support.microsoft.com/kb/314503 for a full description of the
process. This will remove the reference to the 'second OS' in the
mbr. Now reboot and the machine will bootable from the CD drive.

There is no reference to any OS in the Master Boot Record. There
is no reference to any OS in the Boot Sector. FIXMBR will correct an
MBR, and FIXBOOT will correct a Boot Record. But BOOTCFG
will correct a boot.ini file.
