preserving ntfs partition

[John G. Heim]

I have been struggling for a couple of days to create a dual boot system via 
FAI. I now believe I'm doing something wrong with partitioning. The reason 
for this is that I made a dual boot system by manually installing Windows 7 
and then installing debian squeeze. I then saved the grub.cfg file from my 
dual boot system and did a FAI install. Then I copied the grub.cfg back to 
the dual boot system and Windows 7 would not boot. The ntfs partition is 
there but when you try to boot from it, it gives an error message saying 
something about it being unbootable because of a hardware change.  If I 
re-run update-grub, it sees the Windows 7 partition and creates a boot 
stanza for it but it still won't boot. So I don't think the problem is with 
grub.

While I seem to be successfully preserving the NTFS partition, I seem to be 
making it unbootable for some reason. Below is a segment of the output from 
fdisk before the FAI install. After that is the setup_storage config file...

So this is what fdisk showed after I installed debian squeeze normally ...

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1        5100    40960000    7  HPFS/NTFS
/dev/sda2            5100        9726    37161985    5  Extended
/dev/sda5   *        5100        9533    35605504   83  Linux
/dev/sda6            9533        9726     1555456   82  Linux swap / Solaris

This is my setup_storage config file ...

# <type> <mountpoint> <size>   <fs type> <mount options> <misc options>

disk_config disk1 preserve_always:1
