It will then ask you if you'd like to upgrade your system while keeping your files and settings or if you want to perform a custom install. Select your C: drive or wherever your OS is installed. Once you've booted into the installation media, it will prompt you to select the destination drive for the install. An EFI boot device cannot be used on an MBR drive and vice versa. If your system is using an older legacy BIOS, you will select the option that doesn't contain EFI in the label. In my own personal experience, the EFI installs tend to be more tempermental, and sometimes it will take multiple attempts to complete sucessfully. If you have an EFI BIOS, your HDD's/SSD's partition table will likely be set as GPT, and you will need to select the corresponding EFI USB device. When booting from a USB, you should perform a clean boot by holding down Shift while powering off the machine. If that fails, you can try booting from a bootable USB. I've found it to be the second easiest method. If you are mounting the ISO to a virtual drive, you be able to click on the virtual dive letter and select Setup. If that fails, you can download Windows 1803 (April 2018) from the Microsoft website and use the media creation tool to either create an ISO file to mount to a virtual drive or burn to a bootable USB.

It's a straightforward autopilot install. The easiest method is to use the Windows 10 Update Assistant. I don't know if you ever figured out how to sucessfully update your system, but I can share a few different procedures that worked well for me.
