I have Fedora core installed on a partition on my hard disk. I just installed XP on another partition. Now when I start up my computer it goes straight into XP. I don't even get an option to load up Fadora. What am I doing wrong, and how do I fix it?

I guess Windows XP will overwrite your MBR and maybe even your Linux-partition(s)? You should install XP first, and then LINUX.
If your Linux partition is still there you should be able to access it by installing a boot manager.

what program should I use and how do I go about doing that?

I'm using almost the same setup as you do, but with two harddisks. I usually use one harddisk for each OS, and always install the OS's bootloader on its own disk. Then you just choose in BIOS which HD to boot from.

XP's chainloader options can be configured in c:\boot.ini and then you can use a third party program like wingrub to boot your LINUX partition.

Google on wingrub is the best advice I can give. And make sure your LINUX partitions are really there before trying that.

To reinstall grub, boot into FCx rescue mode (boot: linux rescue), search for and mount the FC installation (chroot /mnt/sysimage) and follow the Grub Manual instructions in Chapter 3.3 “Installing GRUB using grub-install” or in Chapter 3.2 “Installing GRUB natively”.

Grub Manual: http://www.gnu.org/software/grub/man...l#Installation

hi Skunkwaffle,
just boot from the first disk of FC1 nad issue the command "linux rescue" at the boot prompt. it drops you into a shell after mounting the fedora partition in read-write mode. from here issue the command " chroot /mnt/sysimage" which will make the mounted fedora partition your root partition. after that issue the command " grub-istall /dev/hdX " where X is a,b,c etc.. depending on how you connect your harddrive in you r IDE chains. if it doesn't complain about any errors, you will have the grub installed in your mbr. type "exit " twice and the system will reboot giving you the menu at the next boot.
vimal...............

vimal's instruction is spot on for replicating the FC bootloader Grub in the MBR.

Your booted FC should not boot Windows because during its installation Windows wasn't there.

To boot Windows in your case you need to know Windows' partition, say it is hda3, and amend FC's /boot/grub/menu.lst to include these 3 lines

title dude said my WIndows is in hda3 and so it is(hd0,2) to Grub
root (hd0,2)
chainloader +1

Being a parimary partition and to install it after FC which would have a swap partition your Windows can either be hda3 or hda4.

thanks everyone. I just re installed FC1 and everything was fine.
