GRUB2 won't boot

mrpringle · 2009-08-09 00:56:36

Hi,
GRUB2 doesn't want to load my grub.cfg file when I boot.
None of my menu entries appear. Only the default arch linux entry.

Is there anything I've missed.

Here is /boot/grub/grub.cfg.

# 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=5

# Set default boot entry as Entry 0
set default=0

# (0) Arch Linux
menuentry "Arch Linux" {
set root=(hd0,5)
linux /vmlinuz26 root=/dev/sda7 ro
initrd /kernel26.img
}

# (1) Arch Linux Fallback
menuentry "Arch Linux Fallback" {
set root=(hd0,5)
linux /vmlinuz26 root=/dev/sda7 ro
initrd /kernel26-fallback.img
}

I'm confused. What other menu entries? You have the two default Arch entries listed above.

When grub starts it comes up with a single menu entry called Arch Linux, and if I click boot it say "error: you need to load the kernel first"
So I guess the first problem is my Fallback entry isn't appearing.

If I edit (by pressing e in grub) the Arch Linux entry it has the following:

set root=(hd0,1)
linux /vmlinuz26 root=/dev/sda1 ro
initrd /kernel26.img

Where did it get this entry from? Not my grub.cfg.

Currently to boot my PC I need to change the boot and root partitions.

I understand now.

I don't remember what I did after I made changes to the file, but here's mine anyway. Hope it helps:

# Timeout for menu
set timeout=5

# Set default boot entry as Entry 0
set default=0

# (0) Arch Linux
menuentry "Arch Linux" {
set root=(hd0,1)
linux /vmlinuz26 root=/dev/sda3 ro vga=792 logo.nologo
initrd /kernel26.img
}

# (1) Arch Linux
menuentry "Fallback" {
set root=(hd0,1)
linux /vmlinuz26 root=/dev/sda3 ro
initrd /kernel26-fallback.img
}

If you do not have a separate boot-partition, /boot must be added to grub.cfg. Example:

# (0) Arch Linux
menuentry "Arch Linux" {
set root=(hd0,1)
linux /boot/vmlinuz26 root=/dev/sda1 ro
initrd /boot/kernel26.img
}

It sounds like you do have a separate /boot partition so the above is not the problem ...........

but remembering that Grub2 has a different numbering convention what are you having to change boot and root to ?

At the moment it looks like you are not progressing past the initial boot screen to see your choice of "Arch" or "Fallback"

I found the problem. It was my fault of course. When I ran grub-install I didn't have the /boot partition mounted and hence the grub files weren't being installed on the root partition.

It took me a while to figure out :-)
