Regarding os-prober see [this answer](https://askubuntu.com/a/1414333/590937), that's not an error but a warning. There is a problem with `/etc/default/grub` or a file in `/etc/grub.d/`. Please add the output of `cat /etc/default/grub` via [edit](https://askubuntu.com/posts/1472871/edit) to your question. Did you edit any file in `/etc/grub.d/`? If so, post the contents of that file too, please. Take a look at `/boot/grub/grub.cfg.new` at line 267 to check which file in `/etc/grub.d/` produces the error.

os-prober has been disabled, you have to edit /etc/default/grub to add: GRUB_DISABLE_OS_PROBER=false and run sudo update-grub

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
