Does Windows Update remove dual-boot?
Windows 10 needs the extra space for the update, so the EXT4 partition is deleted, reformatted, and the space used. The process of dual booting Windows and Ubuntu remains the same, but with one difference: you just need to ensure that Linux is installed on the second disk drive.

Why do I get dual boot when I update my Computer?
When Windows updates it just changes its own partition and it has nothing to do with the boot software. Updating UEFI firmware might affect dual boot because you usually have to disable secure boot (and maybe a couple other settings) in order to get dual boot but most cases it does not.
Where does Grub go in a dual boot system?
When you setup dual boot, a tiny software (typically grub) gets installed either through MBR (Master Boot Record which is the legacy one) or GPT (GUID Partition Table which is the new one) and it is the first section that gets executed when you turn on your computer which basically points to the partition that holds the operating system to start.
Use same edition (Home/Pro) as 1st installed Windows is. Boot from USB installer and select Custom install when asked. When installer ask where to install point that empty partition. Installer continue to install and create boot menu which you can use to select OS you want to start.
