• Grub Issues


    Hi Guys,

    Just installed Antergos Gnome edition on my box. I have 4 hdd installed, the root partition is /dev/sda1 according to the install, but when the install finishes and I reboot, /dev/sda1 is now dev/sdb1 and therefore I get a grub error on boot.

    I know how to fix this, I did it when the same box had Debian installed, but when I run ls (hd1,1) I get unknown filesystem error. I should point out that all drives are formatted as EXT4, and some like (hd0,1), (hd0,2) and (hd0,3) actually list their contents when I ls them, but the drive with my root partition and was set as my boot partition give the error unkown filesystem.

    To add to the confusion, if I keep the Antergos minimal install CD in the drive and I select Boot from Hard Disk, it boots correctly!!!

    Any help gratefully recieved.

  • as far as i know Antergos uses UUID= instead of /dev/sdX for grub…
    But if you can boot to system (Antergos) with the installer CD inserted you can figure it out by taking a look:

    cat /etc/fstab
    

    to see if you have UUIDS or /dev/sdX there

    This will rewrite the grub.cfg with current settings:

    sudo grub-mkconfig -o /boot/grub/grub.cfg
    

    This will reinstall grub to the MBR:
    On EFI Systems:

    sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Antergos-grub

    On Bios Systems:
    sudo grub-mkconfig -o /boot/grub/grub.cfg
