In the old days it was always a case of booting from a DOS floppy
and just running 'fdisk /mbr' which would restore the default
master boot record. I expect that's still prefectly valid for XP
as the mbr's essentially independent from the OS, but likely someone
else can confirm or deny.

It doesn't help with the fact that it seems you have a broken DVD drive,
or that Fujitsu-Siemens are apparently a bunch of morons of course! But
it could well give you a booting XP system again without losing any data.

Probably from any windows computer you can format a floppy and then from a
DOS window do 'sys a:' to make it bootable, then copy fdisk.exe to the a:
drive. Version of windows shouldn't matter; it's just a question of
whether the more recent versions actually ship with the necessary fdisk
and sys programs.

Chance - with MS anything's possible. Likely? No. It'd be a very risky
thing to do anyway; the BIOS manufacturers won't make the assumption that
anything will mess around with the BIOS once the machine's booted (other
than their own flash utility) and so won't have coded for it. If an OS
goes messing around with it then it's likely to result in crashes or at
worst a dead machine.
