  • @rusiru
    First, do you have UEFI boot or BIOS legacy boot?

    The following applies to BIOS legacy boot only:

    • boot with the USB installer stick
    • on terminal:
    lsblk -fm
    su
    mount /dev/sdXY /mnt  # XY refers to the root partition according to lsblk output
    arch-chroot /mnt
    grub-install /dev/sdZ  # Z refers to the disk containing MBR
    grub-mkconfig -o /boot/grub/grub.cfg

    Thanks for the infos about your system, they do help solving the issue.

    Here is some background info: https://wiki.archlinux.org/index.php/GRUB

    Are the linux partitions sda6…sda9?
    It seems sda2 is the EFI partition, right?
    You also have another vfat partition, sda6, why is it in vfat format and not ext4?

    If the above assumptions are correct, you could do the following right after booting with the USB installer stick:

    su
    mount /dev/sda7 /mnt
    arch-chroot /mnt
    mount /dev/sda6 /boot
    mount /dev/sda2 /boot/efi
    grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=antergos_grub
    grub-mkconfig -o /boot/grub/grub.cfg
    

    If any of the commands fail, do not continue running them.

    Strange. If such basic operations cannot be done, then the file system is corrupted.

    The only thing to do (as I see it) is to backup all your important data files and reinstall Antergos. And vfat is not recommended as a file system for any Linux partition, but ext4 is.

    Unless someone else can think of any better alternative.

    BTW, just found this: https://bbs.archlinux.org/viewtopic.php?id=212129
    If you are using refind, then it may help.
