Apathy of XP for Linux..... no more

I didnt know that installing XP alongside Ubuntu Linux can make problems except overwriting Grub. Tonight, after installing XP on my another partition ( off course, not the one which Ubuntu :) ) , when I tried to reinstall (rather resume) Grub by replacing windows boot loader using Ubuntu live CD, I received some unfamiliar errors, I wondered what has happened because I have did this times before (on different machines though) and never had any problem. All I always did was to follow this

Deeper and deeper I digging this problem, I was becoming sure that NT boot loader and NT itself has done some odd. Soon I was live using Ubuntu Live Cd ( I am writing this in Live mode ), even GParted showed two drives overlapping as their sectors were overlapping, running TestDisk cleared the situation:

Current partition structure:
Partition Start End Size in sectors

1 E extended 0 1 1 38911 254 63 625121217
2 * HPFS - NTFS 6374 1 1 16572 254 63 163846872
Space conflict between the following two partitions
1 E extended 0 1 1 38911 254 63 625121217
2 * HPFS - NTFS 6374 1 1 16572 254 63 163846872


Ahhh!!!!, I lost my all Ubuntu Linux drives to Windows. My Ubuntu drive as well as swap space was lost. Can't understand why the hell Windows corrupted those partitions which it can't recognize. What it had to do with Linux drives ?????
Had I be having licensed XP and lots of $$, I would have sued MicroSoft, because none of XP Help Center's multiple boot support http://support.microsoft.com/kb/306559 or any other document in Microsoft Support Center for XP precautions that it can corrupt partitions. MicroSoft is happy to Tell us "How to remove Linux and Instal XP" but they can state that how dangerous NT can be.
