• Grub does not show Antergos


    Hello,

    I am a new member here and i am totally new to Antergos as well. This is my first Arch-based distro to try.

    I have a dual-boot ready 1TB HDD and already have Ubuntu installed on the first partition. I installed Antergos on the 2nd partition but when Ubuntu’s Grub shows up, it does not display Antergos as another option to choose for booting.

    Can anyone help?

  • two options 😉

    more easy would bring Ubuntu-Grub to include Antergos, as you can boot easy into it.

    But as i do not have any knowledge on ubuntu i can not give you detailed instruction now…

    To give you second option (install grub from within Antergos) i need to know some specs:

    EFI System or Bios? and the output of sudo fdisk -l

    I am using EFI. Here’s the result of the result of fdisk -l:
    Ubuntu is on /sda3. Antergos is on /sda5. /sda4 is a actually a custom mouse point I use for media files and other temporary content.

  • Could try from Ubuntu with:

    # os-prober
    
  • @judd Tried that. Rebooted. Nothing changed.

  • needs to rewrite the grub.cfg

    sudo os-prober
    sudo grub-mkconfig 
    sudo update-grub
    

    i do not know if os-prober is installed inside your ubuntu…

  • @joekamprad okay that wored 🙂

    But now I have a different problem. When I choose Antergos from Grub this is what I get:

    What am I doing wrong?

  • Not you it was a missunderstanding by grub-mkconfig i think ?

    It is possible to copy missing information from Antergos to ubuntu from Antergos grub files…
    But i am niot shure how to at the moment…

    I think the proper way is to create a seperate file for adding the Antergos entry to Ubuntu grub.

    I also find this:
    Arch not found from other OS
    Some have reported that other distributions have trouble finding Arch Linux automatically with os-prober. If this problem arises, it has been reported that detection can be improved with the presence of /etc/lsb-release. This file and updating tool is available with the package lsb-release in the official repositories.

  • gksudo gedit /etc/grub.d/40_custom
    sudo update-grub
    

    mounting Antergos root and open /boot/grub/grub.cfg there you will find Antergos menu entry from grub…

  • Hey, also an Arch Linux newb (not to linux though) and I came across a similar issue. Try running " sudo grub-mkconfig -o /boot/grub/grub.cfg" to see if GRUB recognizes the image. If you chose not to install it because you already had GRUB, this is very likely the issue.

    Ubuntu ~ Debian ~ Fedora ~ Antergos
    Dell XPS 15 9530

  • As i know now this is a bug with grub + os-prober here detection goes wrong may because of intel-ucode

    I got a similar problem here with triple boot system (win10 / Archlinux /Antergos)
    I get it solved by running os-prober and rewrite the grub.cfg out of Antergos, booting with LiveIso and chroot into it… then wait like forever to get os-prober ends (i think 15-20 Minutes) and voila i get also a fullscreen Grub-Boot screen with all the 3 Bootentries aviable and working
