I have a multi boot setup on my Thinkpad P43s laptop with windows 10 and Ubuntu 20.04. Everything has worked fine until I changed some Thunderbolt 3 configuration in BIOS to try a fix a well know problem with my Lenovo Thunderbolt Gen 2 dock.
But after applying those changes my machine now boots directly into windows and skips the grub2 menu.
I have found
https://www.howtogeek.com/114884/how-to-repair-grub2-when-ubuntu-wont-boot/
but when I go through those steps from a Live Ubuntu 20.4 USB disk I get this message
Please create a ESP partition (FAT32, 100MB~250MB, start of the disk, boot flag). This can be performed via tools such as Gparted. Then try again.
based on some other post I have found I have tried to disable secure boot in BIOS but that does not help, I have generated this log file:

From the Live USB I get:

So it seems it cannot see my Ubuntu partition.
Any suggestions
