May be best to see details, you can run from Ubuntu live installer or any working install:
Post the link to the Create BootInfo summary report. Is part of Boot-Repair:
https://help.ubuntu.com/community/Boot-Info and:
https://sourceforge.net/p/boot-repair/home/Home/

Does UEFI boot menu show ubuntu entry? May be f10 or f12 when first starting to boot.

Some Lenovo have this, where you have to allow drive to be bootable.
