@gary4gar:
I don't have floppy drive.. So I used USB drive. Used Linux BootCD and installed SGD's GRUB on USB drive.
Booting from USB, I selected to repair and install GRUB, it showed be 2 options, a SWAP partition and my Linux root. I selected root (/dev/sdc6). It detected my Ubuntu and installed GRUB o MBR of 1st HDD, ie my Windows HDD.

After rebooting, I was welcomed by GRUB menu, with 4 options. 3 for Ubuntu and 1 for WinXP.

Select 1st option, Ubuntu, press enter to boot.
ERROR
Filesystem is fat.
Error 15: File Not Found

Selected Ubuntu option, Press 'e', it shows root(hd1,5)

At this point I was about to bang my head.

Press 'e' again, edited the line for hd2, back, back to main menu.. Again check, its hd1 again.
Again followed same, but on screen where it shows list of command to be executed, pressed 'b', it worked.. and smoothly loaded OS.

Once inside, I just changed /boot/grub/menu.lst and changed all those hd1 to hd2.

Now I can directly use GRUB menu without any more editing.

And I am left with
1. GRUB for Windows in boot.ini. - Deleting that line will remove the option.
2. GRUB on MBR of HDD1 - As this can boot both Ubuntu and Windows, I will keep this.
3. GRUB on MBR of HDD2 -This is the HDD which has my linux root. Now how can I uninstall it, as there is already one @ HDD1
4. SGD's GRUB @ USB Drive - How to remove it?

Also my network is not working in linux. I have a static IP provided by my ISP which I use in Windows, I gave same setup in Ubuntu, it shows packets coming in. But I am unable to use internet. I gave IP, Subnet mask, gateway and DNS. It is not part of any domain so that field is blank.
