The bios tells me the hard drive is booted in UEFI mode but I do not see how to find where there is an option to choose between windows and ubuntu.

It's in the Boot menu or equivalent. Every firmware is different. Again, where you find "Windows bootloader manager" navigate to it and press Enter (or follow your firmware's specific instructions), other boot options should be listed there.
Yes, this requires some effort in reading about boot process requirements and your own manual (~5min). If you're installing any OS you don't have the luxury of ignoring basic aspects of the process.

Edit: Booting into the live usb shows an error:
Check finished: errors found in1 files! You might encounter errors.

Your summary report clearly shows all the required bootloaders for Windows and Ubuntu present in the ESP, as it should be.
Furthermore, as expected. it shows the following boot order:
where 2001="EFI USB Device" (perfectly normal considering you're booting a live session from an external USB media) and 0004="Windows Boot Manager" exactly as expected.Code:BootOrder: 2001,0004
So, again as suggested, you should disable Windows Fast Startup feature as that creates issues for dual-booting and even Windows standalone. Then, for the third time in this thread, all you need to do is change the boot stanza back to "Ubuntu" instead of "Windows bootloader manager".
I am still searching for Windows bootloader manager option which is not in bios.
I will check pastebin for your clue 004=windows boot manager which may help me find it
Fast boot was disabled and I see windows boot manager is on sdb2 but I don't see how to access it to change it.

Please, advise me where/how to find and edit the boot stanza from either windows or the live ubuntu usb.
Once I find it I will change it.
First of all, it's in the UEFI ("BIOS") settings > BOOT menu, not in any OS. And surely there aren't that many places where it could be that you miss it.
But it can be managed by software tools thanks to the UEFI improvements over the obsolete BIOS. If you could boot Ubuntu then you would use 'efibootmgr'. From Windows which is the OS you can boot now, there's third-party tool that can be used, EasyUEFI.
There are only two place to look in the bios, Boot priority option and system configuration
Boot priority:
usb
hdd/ssd
lan
odd
System configuration:
Boot Mode: UEFI boot or CSM boot
No place that windows boot manager could hide
I will try the efibootmgr from the usb

I see where I can change Windows Boot Manager to ubuntu but 'how' is not obvious. I have to find that boot file and edit it using nano in my case.Code:xubuntu@xubuntu:~$ efibootmgr BootCurrent: 0003 Timeout: 0 seconds BootOrder: 2001,0004,0002,2003,2002 Boot0000* Realtek PXE Boot0001* Realtek PXE Boot0002* ubuntu Boot0003* EFI USB Device (ASIX AX88772 USB Fast Ethernet Controller) Boot0004* Windows Boot Manager Boot0007* Realtek PXE Boot0008* Realtek PXE Boot0009* Realtek PXE Boot000A* Realtek PXE Boot000B* TOSHIBA MQ02ABD100H Boot0015* Realtek PXE Boot0016* Realtek PXE Boot0017* ubuntu Boot0018* ubuntu Boot0019* Realtek PXE Boot001A* ubuntu Boot001B* ubuntu Boot2001* EFI USB Device Boot2002* EFI DVD/CDROM Boot2003* EFI Network xubuntu@xubuntu:~$
I prefer to make the change using ubuntu not third party windows if I can find how!
Using the third party tool I booted xubuntu into emergency mode.
I am loath to ask for help in this thread so will go try to find where to go from here so as not to risk messing up.
Thank you for the assistance.
EDIT: Checking the journal show errors related UEFI so maybe am in the right thread?
Couldn't get size: 0x800000000000000e
and
MODSIGN: Couldn't get UEFI MokListRT
There are thousands of lines - is it suitable for pastebinit and ask for assistance ?
