hi,
I had a hdd with 2 partions on it, in witch i've instaled on c:\ win 98 and on d:\ win xp and worked fine.
i've bought a second hdd witch is the secondary master and partioned like this first partiton 10GB and the second 70GB.
on the 10GB partition i've instaled fedora core 6 like this:
- /boot partition (200MB)
- swap -> 1GB
- / -> what was left.

i'd instaled grub on /boot partition without afecting c:\ and worked. i was able to boot zod as well as my windowses. but i don't know why the second time i tryed to boot my win it was displaying a message in the down-left corner "GRUB" and it was doing nothing.
the solution found was to boot from the second hdd (the one who has zod instaled on it), but win still didn't work.
then i'd instaled win xp again this time like this c:\ contains win xp.

now when i boot from the first hdd it runs directly into win. when i boot from the second hdd it rund directly into fedora.
this is a solution, but i have to select from BIOS witch hdd to boot from and this is realy annoing.

how can i configure grub or boot.ini to be more... let's say "user friendly" because i'm not the only one who uses this computer and the rest of them doesn't know how to change the boot hdd.

You 'll have to boot off second HD; if you want to add XP to GRUB, you'll have to add this at the bottom of /boot/grub/menu.lst:

title Windows XP
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
chainloader +1

10x...
you realy saved me.
