My goal is that after I re-install grub, everything will keep working as it’s working now.
By ‘boot hole’ I mean the security hole in grub that got fixed lately with the stable update from 2020-08-16. In the review of the update @philm says :
So I want to re-install grub as @philm said. My system is BIOS-MBR but it’s also fully encrypted.
I’m sorry for not being clear enough. I don’t want to destroy ubuntu bootloader. I simply want to re-install grub like @philm said in his latest update. But I fear that re-installing grub will change something in my setup and I wouldn’t be able do boot manjaro because of the fully encrypted partitions that I have.
I don’t know where, currently, the ‘grub screen that asks for password’ (before the grub menu) is residing in my setup, and I fear I would mess it up when I re-install grub.
I guess that the ‘grub screen that asks for password’ is placed somewhere (maybe on sda and not sda1?) and it’s un-encrypted. But I’m not sure how such a thing works with BIOS and LUKS encrypted root partition.
I hope someone can clarify this.
