The HDD might be disabled as a boot device in CMOS.

Your BIOS may support a USB legacy emulation mode that
provides USB FDD access via the BIOS FDD interrupts at
runtime.  This is not necessarily the same thing as
USB FDD boot support.  You might have better luck with
a boot floppy that has *no* USB support, so it can
continue using the emulation.  If the software you're
booting reinitializes the USB controller then it
defeats itself.

W2K uses ACPI.  It takes some effort to make a laptop
work with both W2K and legacy operating systems.  A
laptop BIOS does not necessarily support both (e.g.,
for booting, hibernation, or other power management). 
Does your manufacturer claim that your model supports
any other operating systems?

It might have been using a hibernation file now
instead of a partition, assuming you booted W2K at
least once and gave any auto-configuration utilities a
chance to run.  It might be BIOS-supported, or it
might be W2K-supported.  The latter might be via W2K's
ACPI.  I don't know whether Linux supports W2K
