Re: [orca-list] OT: grub2 and Archlinux

I spot an error in what you write, however I would have thought your windows entry may work.
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. 


# 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 /boot/vmlinuz26 root=/dev/sda1 ro
initrd /boot/kernel26.img
}

## (1) Windows
menuentry "Windows" {
set root=d1,1)
chainloader +1
}




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 “boot.ini” 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 “dd” 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
