this looks a bit peculiar - notice that fstab has both hda and sda
entries... and thinks sda1 is ntfs, whereas grub thinks hd0,0 ( your
first partition) is your linux partition ( ext3) - and grub is right, since
Linux boots

The UUID appears to agree between grub and the fstab for /dev/hda1

Do you have any idea where the /dev/sda1 is coming from? The fstab seems
to think it is ntfs and thus Windows, too... this doesn't make a lot of
sense unless you have another ntfs formatted drive, and you don't mention
that.

Part of the problem may be that Windows is on /dev/hda5 , which is
the first "logical" partition on an "extended" partition. 

If I remember correctly, Windows doesn't like being anywhere but /dev/hda1
or /dev/sda1 -  (hd0,0) in GRUB-speak. I'm not sure if windows needs to be
on a primary partition to boot. hda5 is a logical partition ( i.e. not
primary)

Someone who knows more about Windows might want to correct my assumptions
here, but I would try two things:

1) Run 

sudo cfdisk /dev/hda

 and mark /dev/hda5 as bootable, (toggle the bootable flag for hda5) write
that change in cfdisk, quit cfdisk

2) Edit /boot/grub/menu.lst  . 

Put the following in /boot/grub/menu.lst  AT THE BOTTOM , *after* the line 

 ### END DEBIAN AUTOMAGIC KERNELS LIST

title        Windows 
root        (hd0,4)
makeactive
chainloader    +1

Back up your /boot/grub/menu.lst before editing it, of course - fiddling
with boot-loaders is particularly prone to rendering the whole system
unbootable, but you can repair that if absolutely necessary, by using a
live CD or similar to move files back into place.
