Dual Boot Issue

I first installed Win98 on 'C' drive and then installed XP on 'D' drive. I got the two os listed while booting.

Yesterday, i formatted the 'c' drive and again installed Win98 on it. Now i dont get the option of choosing the operating system. The system simply starts in Win98 although i have XP installed too.

I had saved the boot.ini file before formatting and again pasted it back on 'C' drive after installing Win98. But still i dont get to choose XP.

Which file should i have saved so that i could have got back the page showing the two operating system listed. I just cant start XP now.

Thanks and Regards,
Nisar.
