My linux OS isn't available after installing Windows XP & Vista?!

Hi all;

I've already had 3 OS's on my system:
Ubuntu 9.10 - Windows XP SP3 - Windows Vista
on my system.

My linux (ubuntu) was almost perfect for me (updated, well configured with many installed softwares...)

I have a 300 GB hard disk that was as below:

Win. XP on C drive (100 Gb)
Win. Vista on D drive (100 Gb)
And 100 Gb of unpartitioned space hosting ubuntu!

I decided to install Win. XP & Vista again without any change to ubuntu!

So that, I deleted and formatted C & D drives to install new Win. XP & Vista.

But after that, I can't access to ubuntu and GRUB is vanished now!!

Apparently, Windows isn't able to identify all the OS's on system while installing!
So, the Windows boot manager looses my Linux OS!

Anyway currently, I have only XP & Vista on my system and don't know how should I revive my previous ubuntu?

Is there any method to access to linux OR I should install a new ubuntu AGAIN?!!

Please help, I'm confused!

Windows doesn't care or check what non-Windows OSs are installed, so it wipes the Linux bootloader during installation.

To fix it, you will need to boot into the Ubuntu partition with the install disc, and reinstall GRUB.
