Strange FAT32 resize problem

[Dimitri Butvinik]

Hi,
I hope someone can shed light on this strange problem.
I'm trying to make a master WinXP FAT32 image 3Gb size and save it via
partimage.
Then load master image on many target PCs with diff HD sizes and resize
to max HD size.

1. I create 3 Gb fat32 boot partition and restore from image via
partimage. Everything works fine.
2. I resize partition to 19 Gb (max of my HD) via parted 1.6.4 and it no
longer boots.
Error is "Missing operating system". File system looks good when booted
via floppy, 
none of partition utils report any errors. I just can't boot to WinXP.

These are sectors 1 and 63 from non booting hd.

sector 1

3. If I do the same thing on the same HD only resize to 10Gb or less it
will boot fine.
So far I tried resizing my master 3Gb part to 6,9,10,15,19,38 Gb. It
will stop booting at sizes 15 and bigger.
I haven't tried more granular between 10 and 15 so I can't tell exact
breaking point.

It seems that resizing function is messing up something in FAT boot
sector or MBR on large HDs.
 

Any ideas? Do you want me to provide more specific details?
Thanks.
