I was using Windows XP SP2 and Ubuntu 6.06 earlier...then I had to format the windows partition due to some probs and I used Ubuntu for a few days...Now I have installed the Windows XP SP2 again...but I am not able to boot into Ubuntu. Earlier I was given a choice of either booting into Ubuntu or Windows XP...

I am a complete newbie to Linux....Plz help me...

Please search for 'how to restore grub' in this section. There are so many threads on this same topic.

yes buddy ur Linux boot loader GRUB is gone , restore it . check open source section.

Wanna dual boot Linux on a windows machine without changing your MBR? dd is your friend.

dd if=/dev/(linux boot partition) of=/(path to removable media file) bs=512 count=1

copy this file to your windows partition and add a reference to it in your C:boot.ini. Now reboot and use the Windows boot loader to switch to Linux.
