3) used the same iso in legacy bios with a decade old laptop and everything was working fine in boot menu for live usb.. with uefi live in this laptop, boot menu didn’t work at most options (some tpm error i didn’t write down, something about “TPM unknown error” while trying any options at boot). choosing to boot default entry right after boot was the only thing that worked/booted.
Probably related to the TPM (Trusted Platform Module) enabled chip within UEFI firmware setting, which might be by default enabled (not only for secure boot). So would you mind to disable GRUB’s tpm module this way:
At GRUB menu press ‘c’ to get a GRUB command line
and remove GRUB’S tpm module with this line and press <ENTER>
rmmod tpm
Press <ESC> to go back to the menu.
Removing tpm by default might be one option to consider.
Thanks
