[grub] MacBook Pro 2016 Model A1707 (touchbar) - how to restore dual boot to windows

Hi.

I was trying out an Ubuntu Studio Live USB (Version 20.04.2 LTS Focal Fossa) on my MacBook Pro, which was configured for Bootcamp dual boot to Windows 10.

I ended up trying to install Ubuntu Studio onto another USB stick, which succeeded, but it also installed the grub boot loader on the boot partition.

Meaning, I can still boot to MacOS, but if I select the "Windows" partition, it just starts the grub boot loader, trying to load the Ubuntu install from the USB stick.

I tried to run the Boot Repair as outlined here: https://help.ubuntu.com/community/Boot-Repair

But that didn't seem to change anything.

Here the Pastebin upload from the boot repair utility: https://paste.ubuntu.com/p/PX3nMdyCvW/

How can I either remove grub and restore UEFI booting to the Bootcamp partition, or add a grub config line to do the same?

Thanks in advance for helping me out.
