[ltp] windows won't boot on dual boot T40

[Douglas N. Arnold]

I have installed Debian Woody on a new IBM Thinkpad T40, keeping the
delivered Windows XP around as an alternative, but I am unable to boot
windows.

Lilo seems OK and booting into Linux succeeds, but when I try to 
boot into Windows I get 

  Bad system disk,
  Replace the disk and then press any key
  
I can mount the windows partition under Linux (I have never booted it,
so it hasn't been converted from FAT32 to NTFS), and it looks fine.

Any suggestions on how to proceed would be greatly appreciated.  I do have
the recovery CDs from IBM, but as best I can tell if I run the recovery
program from them it will reformat and repartition my disk and I will
lose the Linux installation.

Here is some background info:
I used qtparted to partition the disk leaving Windows in
hda1 and installing Linux in hda2 and hda4, with swap in hda3.
fdisk reports:

Disk /dev/hda: 80.0 GB, 80026361856 bytes
240 heads, 63 sectors/track, 10337 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes

Thanks in advance for any help. -- Doug Arnold
