I have it to fast and the default ubuntu-22.04.1-server installed. Booting is good. I've read before that ESP is required as standard. Now, i will try to found efi's files...

Does anyone have any ideas about this?

This is how you can check the type of boot:

sudo efibootmgr
EFI variables are not supported on this system.

...than BIOS booting.

Obviously you use bios boot, not efi boot, therefor you don't have an ESP and there are no efi-files in bios boot. Don't try to find them, they do not exist.

Thank you so much! I can check that: `sudo efibootmgr EFI variables are not supported on this system.`

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.
