• Windows Update, Grub Reinstall failed


    Hi guys. I dual boot Windows 10 and Antergos, and my laptop decided to update today. Well, the classic Microsoft move occurred again, and I’m left without a working GRUB.

    I’ve done a bunch of GRUB reinstalls like this before, so I figured no worries. After finding @joekamprad great guide on EFI GRUB installs, I followed it, and the system said that it installed correctly. However, when I try to run the update GRUB for it to recognize Windows, it failed for some reason. I tried to research the issue, but came up blank, hence my post here. :)

    What did I do wrong?

  • @mach01dan may you are on the LiveIso?
    You need to chroot first into the Antergos on your HD!

  • @joekamprad Yes, I’m on a live ISO. I chrooted using this command: arch-chroot /mnt

  • Do I do anything special to this command “arch-chroot /mnt” or leave it the way it is? It was my understanding that I shouldn’t need to change anything.

    Update: So I’ve actually figured out a way to get around this weird bug. I used this great piece of software called Rescatux that is basically a special live usb with a purpose build feature set of re-installing, updating, or checking GRUB settings.
