How to rename other OS in grub (without grub customizer)?

us flag

i have a main system (ubuntu), a windows 10 and 2 other ubuntu installed. I can rename the main system in /etc/default/grub. How can i rename the other ubuntu systems and the windows?

I'll never install grub customizer again. I've tested it a few years ago and could never uninstall it.

See `/etc/grub.d/30_os-prober`

its very simple for other *nix systems. os-prober reads information about other *nix systems from /etc/lsb_release. i was able to change the names in grub menu by changing the name in the file. but this don't work for windows. is there an other file where os-prober reads information about the windows?

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.
