Hello there! I am facing "The GRUB boot loader was previously installed to a disk that is no longer present...". I tried everything from here (https://itsfoss.com/could-not-get-lock-error/)but it doesn't work. What could it be?

The link you looked at is for a running system when the package manager can't exclusively lock a package to update it, that is not your problem!
You need to reinstall a grub loader, as it suggested you do in your first image.
Your second image showed a terminal so I take it you can get a terminal OK?
