I believe that should be (hd0 and (hd1 and not just d0 or d1.  I'll
have to look more closely but didn't think there was an error in his
grub.cfg file but after a while, this stuff starts looking a lot alike
so I could have missed something too.

The error is that you set the root to hard disk 1 partition one and
then refer to the linux kernel being in / passing it the argument
root=/dev/sda1 (in fact you had miss typed /dev/sda1 but I knew what
you meant). This seems to imply you don't have a separate boot
partition, but in that case the path for the kernel and initrd is
/boot/. If you only have one partition (IE. no separate boot
partition) then here is what your configuration file should read.

}

}




Does this help?

Hello,

I can't verify the accuracy of the coding used. If you boot and
get nothing (no speach) you might have the Grub command line.
Grub followed by a flashing Underscore.

I haven't found the time to explore this. Perhaps it is as
simple as typing a configuration file in order to bring up a menu.

If you are not on the Vinux list here are the notes I just posted.

Hello List, Notes on duel boot: Windows&Vinux, boot.ini&Grub, 2
drives (ATA&SATA)

Some of you have asked about duel boot and my system setup is
different. Here is what I have learned during my first six months
trying to learn Linux & Vinux.

My desktop system had Windows XP and one drive on an IDE (ATA)
cable/connector.

To install Linux and keep Windows, it was recommended that a
second drive (dedicated for Linux) would be safer. I got the
second drive which turned out to have a SATA cable/connector.

I believe that the SATA is the newer technology and that would
explain why my BIOS looked first to a SATA before ATA for the
operating system.

First I installed Vinux 2.1 CLI (Debian) to partition 1 and the
Grub 1 gave me access to it and Windows.

Then Vinux 1.5 (Ubuntu) was installed to partition 2 and the Grub
menu listed all three Operating systems but gave access only to
the Vinux 1.5.

My Windows MBR was destroyed and it had to be restored.

Now, whenever installing another version of Vinux, I disconnect
the Windows drive.

The newer versions of Vinux 3.0 are being installed into partition
2 and the Grub 2 menu does not show Windows because that drive is
disconnected.

Since Windows is my workhorse, I had the BIOS changed to look
first to the ATA (Windows) drive.

I added the entry to the Windows âboot.iniâ file to point to the
Vinux 2.1 CLI.

Currently my only way to access Vinux 3 is through the boot device
list. On my system the F8 is held down for about 15 seconds. Then
arrow down to highlight the Vinux drive and press ENTER. Grub 2
comes up with Vinux 3 as the default.

Many of you have only one hard drive. This makes it important to
learn how to backup the MBR of your Windows system. Learn to use
the Linux âddâ command. Learn to copy the first 446 bytes of the
drive as a backup to restore if necessary.

I hope some of this will help some of you.

Peter

Hi all,
Sorry for being off topic.
I am searching for a solution but I haven't found any as of yet.
But maybe any of you have an idea.
I am having issues with the old Grub as some of you already know
so I did a clean installation of Arch.
My harddrives are one SATA drive, which shows up as /dev/sdb and
the other which is an IDE drive shows up as /dev/sda and in the
bios it is the SATA drive that is set to boot first and I cannot
change that right now. And I want to install Arch onto /dev/sda
OK, here is what I did:
On the Arch linux wiki it was recommended to skip the install
boot loader after the installation was complete, so I did that.
Then, I installed grub2 and removed the old boot loader as it
prompted for that.
Then I chrooted into the newly installed system wiht the
following command, also taken form the Arch Grub2 wiki:
mount -o bind /dev /mnt/dev
chroot /mnt bash
I reviewed the content of the file that was created in
/boot/grub/grub.cfg
Here is what the file looks like:

# Config file for GRUB2 - The GNU GRand Unified Bootloader
# /boot/grub/grub.cfg

# DEVICE NAME CONVERSIONS
#
# Linux Grub
# -------------------------
# /dev/fd0 (fd0)
# /dev/sda (hd0)
# /dev/sdb2 (hd1,2)
# /dev/sda3 (hd0,3)
#

# Timeout for menu
set timeout=>
# Set default boot entry as Entry 0
set default=>
# (0) Arch Linux
menuentry "Arch Linux" {
set root=d0,1)
linux /vmlinuz26 root=ev/sda1 ro
initrd /kernel26.img
}

## (1) Windows
menuentry "Windows" {
set root=d1,1)
chainloader +1
}
Then I issued:
grub-install /dev/sdb --no-floppy
And I got no errors.
After rebooting the machine nothing happens.
So please, if you have any ideas please let me know.
Many thanks,
Christian
