Boot Menu looped, how to fix it?

Question

BIOS

Hello, my laptop model is Lenovo V110-15AST
I can’t tell you the reasons, my aunt’s laptop, and when the problem arose I was not around.
I read a lot of publics, and reviewed a lot of videos on this problem (the Boot Menu got stuck). Everything is standard, no matter which of the items you choose, it flips back. The Esc, Delete keys and the Ctrl + Alt + Delete combination do not work, it remains possible to enter Bios. Disabling Secure Boot does not help, Boot Mode is initially set to UEFI, when I change to Legacy Support, a black screen pops up with an inscription in English (how unexpected) where they give me warnings, they say something, something has been changed and offer two buttons - Esc to reject the change and continue, and F12 to change the load dimension to use PCR, if you try these two options, nothing changes. Aunt took a laptop for work, and there are the necessary files, and it is needed for ... In general, I beg you, answer me.
