Grub Boot Loader Help
 

I am having some problems duel booting windows and linux.

I am using Linux Fedora Core 4 and Windows XP Pro SP2.

Linux is on an IDE hard drive and Windows is on a serial ata hard drive on the first controller.

I keep getting error 13 when I try to boot into Windows.

Here is my grub.conf file.

default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.6.11-1.1369_FC4)
root (hd0,0)
kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.11-1.1369_FC4.img
#title Windows XP Pro
# rootnoverity (sda1,0)
# rootnoverify (hd0,0)
# chainloader +1

I tried some things and just commented them out. So I guess in short my question is, what entries to I use boot Windows on a serial ata hard drive on the first controller, so SATA1.

Any help would be greatly appretiated.

Thanks,

Look at the device.map file in the /boot/grub directory. I would guess it is something like:
(fd0) /dev/fd0
(hd0) /dev/hda
(hd1) /dev/sda

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

The map lines are necessary because windows wants to be the first drive. See grub documentation for additional details. The first hard drive found will be hd0, the next hd1 and so on. Partitions IDs start at 0 i.e. hd0 is hda1.

Welcome to LinuxQuestions. You can find lots of help by searching the web and this website. As a newbie the difficult part is knowing what to search for.

My device.map file is exactly as you stated. I did everything you said but it still gives me the same error.

13 is a bit odd - open a terminal and post the output from (that's ell as in list).

Dunno - pls list your grub.conf

This is my device.map file
(fd0) /dev/fd0
(hd0) /dev/hdb
(hd1) /dev/sda

Is this a typo or a copy and paste? Should be rootnoverify.

For the love of... It was a copy and paste that may be the problem I'll try.
