Hi Chris,
Thanks for this. Just had a fantastic honeymoon, but now back in the real
world and onwards with trying to fix this.

The folder /efi/EFI/Microsoft did not exist, which tends to confirm your
suspicion that the the partition was reformatted during the upgrade. I
manually created the folder and copied bootmgfw.efi from \Windows\Boot\EFI\

Here is the generated grub.conf as requested. I've had a look at the file and
there is no mention of Windows anywhere. The windows partitions are mounted:
[root@gary ~]# mount|grep sda
/dev/sda3 on /boot type ext4 (rw,relatime,stripe=4,data=ordered)
/dev/sda2 on /boot/efi type vfat
(rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=winnt,errors=remount-ro)
/dev/sda5 on /windows_recover type fuseblk
(rw,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
/dev/sda4 on /windows type fuseblk
(rw,relatime,user_id=0,group_id=0,allow_other,blksize=4096)
[root@gary ~]# grub2-mkconfig -o ~/Downloads/grub.cfg
