Please DONT post images of command output that can be posted as text, only post images if there is NO-OTHER-WAY to provide that info…
Do you mean you can access the console with those keys from your normal boot or only from the Live-USB?
(If it is only from Live-USB, there is no need to mention that as that is the expected behavior.)
Why do you believe your problem is caused by Grub?
Your second image shows that you already past the Grub stage…
Please provide output of the following commands in their own code blocks, as explained in the link i provided above:
lsblk --fs --all
efibootmgr --verbose
