Hello,
I have a HP laptop on which I have Windows 10 installed on an SSD, and I have a USB on which Ubuntu is installed. I was previously able to select which OS to boot to, but since upgrading to Ubuntu 19.10, I couldn't choose any more and could either boot to windows or Ubuntu using the boot menu in the BIOS. However, now I cannot seem to boot to Windows and don't have the option anymore in boot menu.
The main problem seems to be grub, although I am not sure exactly how to navigate the problem as I have limited experience with Ubuntu. I ran a boot repair yesterday and had the following report:
https://paste.ubuntu.com/p/c5MQd932dp/
I tried running the boot repair again today, which gave me the following code to enter in terminal and it seems to be a problem it is having even though I have tried a few workarounds:

I have exhausted my googling options and so would request help from this forum in solving this persistent problem.
Please let me know if you require any further info, thanks!
