• Installing Antergos over Ubuntu (with Win10 dual boot)


    Hey guys, I had a really perfect system going on with Ubuntu installed in EUFI mode with no problems at all. Fast forward to today, I wanted to try more bleeding edge features and arch linux so I installed Antegros following this guide: https://itsfoss.com/dual-boot-antergos-windows-uefi/

    However, grub from ubuntu persists and shows grub recovery with no boot menu items at all (from the old ubuntu)

    I went to disk management in windows and simply removed the ubuntu storage to replace it with Antegros. I disabled secure boot and the antegoros USB drive finally boots up. I install integros. Reboot and grub still there.

    I try fixing it with windows recovery commands /fixbrm and other commands but boot issue did not get solved… i still see old grub lingering! I even installed supergrub on usb drive but I cannot see any automated “repair” options… it just shows me everything I have on all drives. I installed windows recovery to do boot repair to no avail.

    This is C drive with dual boot (1 hdd only). partiooned with win 10 most of the space and then /home /boot /swap etc.

    How do I install integros cleanly and remove old grub installations so I can boot normally?? Should I keep secure boot on?

    Thanks for the help!

  • This is C drive with dual boot (1 hdd only). partiooned with win 10 most of the space and then /home /boot /swap etc.

    Next is to create the /boot/efi partition. Actually, we don’t need to create it. Windows already have it. We can just specify the path to it. Just make sure to NOT format it.
    Do you link to EFI-Boot or do you create A NEW ONE?

    If there is gone something wrong with grub installation, you can simple redo it from booting with Live Iso and chroot into your installed Antergos:

    https://antergos.com/wiki/miscellaneous/how-to-fix-grub-with-efi-boot/

    $ sudo su
    $ mount /dev{/ ROOT} /mnt
    $ mount /dev/{boot} /mnt/boot
    $ mount /dev/{EFI-boot} /mnt/boot/efi
    $ arch-chroot /mnt
    $  grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Antergos-grub
    $ os-prober
    $ grub-mkconfig -o /boot/grub/grub.cfg

  • @joekamprad Thanks so much for your help!

    I see all these Entries in my HD when I press F9… how do I clean this up? I only want the last Antegros entry you see and of course, Windows boot loader. 0_1498161215402_20170622_133450.jpg

    And once I select antegoris_grub_mixe I don’t see windows on there only antegros is listed: 0_1498161266894_20170622_133557.jpg

  • Never see this antergos_grub_mixe entry… the other one antergos_grub do not work?

    Finding Windows 10 for Grub:

    Go into Antergos, find terminal and type in the following command:

    sudo os-prober
    

    (if you don’t have os-prober install it using the following: sudo pacman -S os-prober)
    Once this is done it should list something similar to what I have below:

    /dev/sda2@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
    

    Great! You found it. Now to update your grub so that it can see it.
    If nothing is shown up it can not find your Windows installation…and we need to tage a look deeper inside…

    Update grub:

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

    Reboot

  • @joekamprad Wow that was easy OS probe is awesome thanks for the tip!

    However now I still see the old Ubuntu 16.04 grub rescue which is showing by default when I first boot ( I have to press F9 to boot antergos)
    0_1498164144188_20170622_163737.jpg

    the other antergos entry shows grub rescue as well. (3rd entry in my first pic)

    Is there something like Os prober to remove these old grub loaders from prev installations and show me the last antergos one by default

  • If you go into your BIOS settings, (at least on a DELL) under the category “Boot Sequence” you can click the ones you wish to remove and simply “Remove” them.

    This is the cheaters’ way though, because I have found that it doesn’t delete the entries at all, it only removes them from the boot sequence.

    Hope this helps:slight_smile:

  • @A-User Ha thanks for the input! However I don’t see that option! And I rather remove them properly and get it over with :)

  • OK:grinning:.

    Thank you for at least considering my suggestion !!!

  • @bplanet

    Here you can find a longer explanation of how GRUB works: https://wiki.archlinux.org/index.php/GRUB#UEFI_systems_2

    Maybe it gives you some more ideas what you can try?

    I also found this statement: “If Arch Linux wasn’t recognized after an update-grub then probably your Arch installation is missing the package lsb-release.” (see end of article https://wiki.manjaro.org/index.php/Restore_the_GRUB_Bootloader).

  • Just wondering.
    Did you install Antergos on the same partition as Ubuntu. And did you format that partition before installing?

    Never to old to learn.

  • @axioma said in Installing integros over ubuntu (with win10 dual boot):

    And did you format that partition before installing?

    Just to be clear, I’m assuming you are talking about the /boot/efi partition?
    (Just trying to clear things up for @bplanet and resolve any possible confusion before it begins).

  • There is no problem with Grub, entries are present and also Antergos is bootable with them.

    Theme is about EFI Bios and howto get old entry remove and choose the right one to bootup autmatic.

    Only one Grub related thing should be interesting: are there stuff from ubuntu still persist inside the EFI-Boot (fat32) partition ?

    how to add system logs

  • @Keegan Indeed. Not so lang ago I forgot to do this with a fresh install, and got a whole list of boot options of installs I thought where long gone. Even the Windows boot option; although I had removed that system shortly after I bought my machine some five or six years ago.
    My BIOS was a mess till I reinstalled Antergos again.

    I also once installed (non EFI) a system forgetting to format the /root partition. That resulted in strange behavior too.

    Above is not meant as advice, but as a hint based on my own experience. Others are probably better equipped to solve the problem.

    Never to old to learn.

  • Thanks @axioma! It’s nice to hear (and thus have the opportunity to learn from) others who are farther down the road I am currently traveling.

  • @axioma I think I forgot to format, I went to disk management in windows and simply “removed” the partition then installed Antergos over it. No i did not format boot/efi (I just linked to it during installation)

    I thought that would mess up windows boot loader since that’s where it is?

    Perfect!

    I think I forgot to format

    Hoefully the solution is as easy as fixing this:slight_smile:.

  • @Keegan come to think of it I installed twice, the second time I did format (simple partition format) then reinstalled… same the ubuntu grub still shows up first by default.

    Should I be formatting via linux live usb instead?

  • If you are merely referring to formatting it inside Cnchi in the Live Environment, then yes:slight_smile:.
