[ubuntu] Can't boot to Windows anymore (Dual boot Windows 10 / Ubuntu 20.04.1)

Hello all,

I hope this is the right place to post this.

So I installed Ubuntu 20.04.1 a few days ago on my PC. I had a dual boot with Windows 10 on my first SSD (which was installed first), and Ubuntu on my 2nd SSD (I followed these instructions: https://askubuntu.com/questions/7269...te-hard-drives), and it all worked fine initially.

However today after a Windows update, my PC booted straight to Windows. After entering in Windows command line I was able to get GRUB back and to boot into Ubuntu.

Unfortunately now I can't boot into Windows. Windows Boot Manager does still appear in GRUB but selecting it does nothing.

I unsuccessfully tried , as well as creating as recommended here: https://askubuntu.com/questions/2179...ntu-how-to-fix. I did get a "Windows (UEFI)" entry in GRUB but it didn't have any effect either.

Finally I installed boot-repair, launched Recommended repair, and got a "Boot successfully repaired" message with the following pastebin: https://paste.ubuntu.com/p/FgwRKnvgD9/
However now I do not have access to GRUB anymore, it boots straight to Ubuntu instead.

I also noticed that now in UEFI, the fixed boot order priorities includes my 2nd drive (Ubuntu) instead of the first. Another option, UEFI Hard Disk Drive BBS Priorities, gives a list of 3 options: Ubuntu SATA1 (which I set first, as apparently recommended by boot-repair), Windows Boot Manager SATA1, & Ubuntu SATA2. Still boots straight to Ubuntu regardless.

So now I'm unsure what to do to get GRUB & Windows back. Any help would be much appreciated.
