i was having the dual system ie windows xp and fedora core1 .i have made the changes to master boot record using the command
now during booting i dont find my fedora option ,i havent deleted any partition
all the partion are as it is
how can i get my dual options on booting back
ie
dos and fedora

You could boot a live linux CD, mount your partitions and re-run either lilo or grub-install.

you mean i should run the whole setup again

Here we go. If at all possible, boot into Init level 3 (gentoo would do this)

1. boot the CD
2. create a new folder, mkdir /fedora
3. mount all your partitions under /fedora. Mount / first, followed by any others.
4. type chroot /fedora /bin/bash
5. type env-update
6. type source /etc/profile

You are now essentially running your fedora system

7. Re-run the bootloaders install. For lilo, just type lilo, for grub it is grub-install /dev/hda

REBOOT.
