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
.

you need to edit /boot/grub/grub.conf. the line `default=___' should
say `default=1' if F11 is the 2nd entry
on your list.


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.

Thanks for your responds.
