Grub error

Hi people,
I have some problems whit my grub configuration. I have installed Fedora and wont a dual boot between that and XP. So I got two HD's, and from a fdisk -l i gets:

Code:

Disk /dev/sda: 81.9 GB, 81964302336 bytes
255 heads, 63 sectors/track, 9964 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1          13      104391   83  Linux
/dev/sda2   *          14        9964    79931407+  8e  Linux LVM

Disk /dev/sdb: 40.0 GB, 40016019456 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1        4864    39070048+   7  HPFS/NTFS

And here's my grub.conf:

Code:

#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.23.1-21.fc7)
	root (hd0,0)
	kernel /vmlinuz-2.6.23.1-21.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
	initrd /initrd-2.6.23.1-21.fc7.img
title Fedora (2.6.21-1.3194.fc7)
	root (hd0,0)
	kernel /vmlinuz-2.6.21-1.3194.fc7 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
	initrd /initrd-2.6.21-1.3194.fc7.img

#boot=/dev/sdb
title=Windows XP
	rootnoverify (hd0,1)
	makeactive
	chainloader +1

I have also tried to set the sdb disk to (HD1,0). I really hope someone can help me out..

Have you tryed changing this

Quote:

title=Windows XP
rootnoverify (hd0,1)
makeactive
chainloader +1

to this

Quote:

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

We also need to know what was installed first, and what errors you are getting. eg do you get a grub menu when you boot up?

The map command is required because Windows has to think it is #1 (ego issue, I guess)

And GRUB has to be installed so that it points to its files in /boot/grub. This would be automatic when installing Fedora.

for sdb1, the equivalent "grubspeak" is indeed hd1,0 Grub uses only numbers and counts from zero

sda1 = hd0,0
sda2 = hd0,1

sdb1 = hd1,0

etc.

Thanks now my grub is working perfectly

I have a really bad power supply to my computer with only two correct DC outputs. So I can only have one HD and the DVD player or both HD's

So when I installed Fedora I only had one HD and my DVD of cause. But then I had to inset the second HD (the one with XP) and reconfigure grub.

Now all works tanks to you guys
