• Antergos not booting


    Hi, I broke something in my system. It does not boot anymore.!
    0_1538593898155_e595d5df-88fb-42a7-908a-fdc1d5cdff06-image.png

    CTRL+ALT+F2 does not help…

    Does any of you know how to solve the pb please? Thx again for your kind help.

  • @longliveantergos
    What was the last thing you did (describe in as detail as possible) after which it didn’t boot anymore?
    And do you still have the USB installer stick around?

  • looks like you need to rebuild kernel-image while booting from liveISO and arch-chroot into installed system…

    arch-chroot is discribed here in the first part:
    https://antergos.com/wiki/miscellaneous/how-to-fix-grub-with-efi-boot/

    rebuilding kernel image like this:

    mkinitcpio -p linux
    grub-mkconfig -o /boot/grub/grub.cfg

  • @manuel Thx. I deleted some of the programs I don’t need…

  • @joekamprad Thx for your help. When I boot from Live USB (non-graphical boot, correct?) I get “ant-18: login”… I type the usual login (correct?), the line “Password:” appears, I type it - dead end. Even if I consider “q” and “a” could be inverted, the pw is never accepted.

  • @joekamprad This is zhqt I get.

  • LiveISO graphical boot is what you need…

    on you fdisk -l output i do not see any Linux installation… no ext4 or other Linux related filesystem…

    so where do you have installed Antergos? on the 931.5 GiB or the 232.9 GiB Disk???

  • @joekamprad on the 931.5 GiB normally

  • @joekamprad said in Antergos not booting:

    LiveISO graphical boot is what you need

    I boot from a LiveISO USB stick then select Antergos Live and open a terminal. Correct ?

  • @longliveantergos yes ;)
    but if fdisk -l do not show any linux partition, do not know where is yout root [/]

  • @longliveantergos
    Could you show the output of

    lsblk -fm
    

    I deleted some of the programs I don’t need…

    That may be the reason. Can you reinstall them? If not, then make a backup of your data and reinstall Antergos.

  • @manuel said in Antergos not booting:

    Can you reinstall them?

    I cannot reinstall them because I do not have access to this partition, at least I don t know how to access it.

  • @longliveantergos
    Can’t see anything Antergos related stuff in your lsblk -fm output.

    So it is time to reinstall Antergos.

    Make sure you have correctly created the USB stick: use Etcher or Rufus (in DD mode). On a linux machine you can use the dd command.

    Then be careful with the choices in the installer, do NOT just click yes to all questions, but think what each question means. Ask here about the choices if you are not sure, somebody will surely help you.

  • @manuel said in Antergos not booting:

    Can’t see anything Antergos related stuff in your lsblk -fm output.

    That is probably normal since I am booting Antergos Live from a USB stick and using that terminal. Maybe there is a way to access the correct partition…?

    If I really MUST reinstall, how do I save my files first, please? With DOS?

  • @joekamprad I think fdisk -l does not show a Linux partition because I am using the terminal after booting Antergos Live from the USB stick.

  • @longliveantergos
    You need to specify whether you are booting in UEFI mode or BIOS legacy mode. That is one thing that may have gone wrong for some reason.

    Try booting with the USB stick. If you see both UEFI and BIOS legacy booting options, try both in turn; at least one of them should boot.

    Then you can start a terminal and give again command:

    lsblk -fm
    

    You should see Antergos partitions, too. It doesn’t matter if you are booting from the stick, as long as you boot in the right mode.

    If you don’t see any Antergos partitions, then it is quite tricky, and an expert is required to solve this. Your files may be there, but for some reason they seem to be hidden. There are some recovery tools, like ddrescue, but I have no experience about them - and improper usage of these tools may cause even more damage.

  • @manuel Thx, I try and let you know.

  • @manuel When booting from USB stick I have the following options (see picture). I select Start Antergos Live.

  • @manuel Then I can Try or Install.
