Linux – Grub won’t boot Arch Linux

arch linuxgrub-legacy

Notice: This is not about dual booting, I can setup GRUB to dual boot with Windows 7 later. I just need to be able to get into Arch Linux.

Last night I installed Arch onto my computer via netinstall and it all went smoothly, but when I went to reboot… it loaded up the GRUB menu and it listed Arch Linux, but when I select it, I get "Error 15: File not found."

I've been googling and trying various way to fix this problem but I always get the same error.

Some info about my partitions:

  • /dev/sda:

    1. Windows 7 System Reserved
    2. Windows 7

  • /dev/sdb:

    1. Data (Movies, Music, etc..)

  • /dev/sdc:

    1. Separate Boot Partition
    2. Swap
    3. Separate Home Partition
    4. Root

  • /dev/sdd:

    1. Pendrive

The followings are outputs of various programs and contents of various files.

The main thing that seems wrong here is that in the line

kernel /vmlinuz26 root=/dev/disk/by-uuid/2a53bdc8-7a9a-4dd2-9aef-5b7b4c3e74a4 ro vga=775

You are using the uuid for /dev/sdc3 which is your /home partition, you should be using the uuid for /dev/sdc2 which is your / partition.

Also... the output from sudo blkid does not match what is shown in fstab. In blkid the swap partition is /dev/sdc2, but in fstab the swap partition is /dev/sdc4...

You need to figure out these descrepencies.... then you can try to re-configure your grub.conf

Some pointers:

  • Have you tried other values of root, like root (hd2,1) ?

  • Instead of

    kernel /vmlinuz26 root=/dev/disk/by-uuid/2a53bdc8-7a9a-4dd2-9aef-5b7b4c3e74a4 ro vga=775`

    you could try things like

    kernel /vmlinuz26 root=/dev/sdc2 ro vga=775

  • Make sure that /boot/kernel26.img exists.
