Windows zapping by Stage1.5?

[Bob Bell]

Hi,

I had Windows 2000 installed on my notebook computer.  I recently shrunk 
my NTFS partition and installed Ubuntu, which left my drive partitioned 
as follows:
   /dev/hda1 * NTFS (Windows 2000)
   /dev/hda2   Linux
   /dev/hda3   Extended
   /dev/hda5   Linux swap

Ubuntu installed grub as a boot loader, which used chainloading to load 
the Windows 2000 boot loader when selected.  Originally (i.e., the first 
time or two), this worked fine.

However, now when grub loads the message I see is "Grub loading 
Stage1.5".  I do not see *any* further output.  I'm guessing that this 
means that grub failed to load stage 1.5.  Since stage 1.5 is supposed 
to be right after the MBR, I'm thinking that perhaps something in 
Windows is not playing nicely and is overwriting it stage 1.5 ?

If I boot from a CD and run `grub-install /dev/hda`, all is well.  At 
least, until the next time I try to boot after running Windows for 
a while...

Is there a recommended way to deal with this situation?  Other than 
erasing Windows, of course. :-)

Thanks in advance for your help.  FYI, I'm not subscribed to the mailing 
list, though I did try searching the archive, Wiki, Google, etc.
