Dual booting with WinXP and Fedora 11.

Hard Drive 0 sda1 WindowsXP

Hard Drive 1 sdb1 /boot Fedora 11

Isn't the command grub-install /dev/sda what you do to write grub to boot from sda ?

I ran that command from fedora 11 but it still wants to boot from WindowsXP


The two hard drives are not set up master, slave , they CS selected on a Dell
Here is my menu.lst file.
I do have a separate /boot partition sdb1
WindowXP is on sda
Fedora 11 is on sdb
With this menu.lst, I did a, grub-install --recheck /dev/sda , and when I do a reboot I get a Error 21.

Do you mean it tries to boot XP by default, or just that it doesn't even load Grub?

Well right now it comes back with a Grub Error 21 .

This is what Mr. Google came up with:

You may want to try supergrub.

It comes back with the error when you try to load windows or linux or both?

have you set BIOS to boot from Fedora HDD?

I found this interesting post:

Given what anaconda tells you in the comment at the top of grub.conf, I would suggest to edit grub.conf by adding the line

boot=/dev/sdb

after

title Fedora (2.6.30.8-64.fc11.i586)
root (hd1,0)
kernel /vmlinuz-2.6.30.8-64.fc11.i586 ro root=UUID=aab20ab4-9875-44d9-b8bb-57d8101d299b rhgb quiet
initrd /initrd-2.6.30.8-64.fc11.i586.img

And see if that helps. At least then you have the relative path to /vmlinuz and /initrd
