How to boot XP from win98?

Hi there,

I had 2 os on my pc with 3 partition. I had win98 in my first patition. Win xp on the second, which is NTFS. and the third is only for backup. My problem is that i had some troubles with win 98 and had to format and reinstal it. Now i cant boot my Win Xp. I dont get the option to chose to chose which OS i want to use. since xp is on NTFS i cant even access my files on the second partition.
Can someone advise?
