I need to have such, and I'd like to add it to an existing machine with a large

problem is that while I've put Fedora (and Linux back to SLS and Slackware on
2.2 kernels) on Windows machines, I haven't done it with anything else after,
Linux has always been "the last OS you'll ever need" for dual boot.
I'm not worried about the grub.conf, but the boot sector could be an issue, I
have seen reports that XP with patches and Win7 check the boot sector now (XP at
patch level 3). other than having to rewrite the boot sector, is that going to
be an issue? Any other things I should know?

I have seen some reports that certain hardware types require the Windows
bootloader code and if it is overwritten, say by grub, that it puts
Windows into repair mode when booting Windows but I have never
experienced that issue myself and I would think that you wouldn't
either.
That's the kind of thing I was worried about, I have had that issue with the
Linux installed in the boot sector rather than the partition, but I haven't done
Windows recently.
You can actually use the Windows bootloader to give you a choice of
which to boot instead of grub if you wish - not really that big of a
deal and there are many examples found easily with Google.
But if you have a Linux rescue boot disk (i.e. the installation DVD),
it's rather trivial to boot into rescue mode, chroot to /mnt/sysimage
and then 'grub-install /dev/sda' to reset the mbr for grub again, but
then you would have to create a grub entry for booting Windows - I have
sample at bottom).
Thanks, as noted I've set up the chain loader installing after Windows was in,
but I never did it this way before. I even have examples of doing dual boot with
LILO from back in the old days, although I don't ever expect to reuse them.
Note to others, do understand what the (hd0,1) means, that's typical for
"Windows first" installs, but not for "Windows as afterthought" cases.
