Dual boot problems with mandrake 10 community

I have installed mandrakelinux 10.0 on partitions at the end of my disk number 2. On the first disk and at the beginning of the second disk is installed XP, the partitions are formatted NTFS. When I had installed Mandrake and re-booted the computer, it shows only a lot of number "9".
However the method i try for the dualboot. Lilo on the MBR, on a floppy disk,or from the NTLoader, it's the same result. I'tried a lot, what can i do
now. Thank you for any help you kan give me.
