Bootcamp - Windows cannot locate the disk and partition specified

I am currently trying to download Windows 10 April update on my iMac. It got through the whole partitioning process but when booted into the Windows setup, I get this error (image below). I am currently using macOS Sierra 10.12.6(should be the latest update), and tried other things like running first aid on the HD - but nothing seems to work. Please help me out - anything will be truly appreciated!

Thanks in advance!

Found the issue: had to reset the SMC and NVRAM. Figured out through Apple support. Thank you so much for your time in helping me out, truly do appreciate it.

Ah, you need to Install Win10 again before using the Update...

I don't know if I should have referenced this before, but I did have Windows 10 up and running perfectly before. I just wanted to resize the partition so I deleted the old partition and resized it into a newer one. I am now trying to download Windows 10 April update, but it is not working.

Thing is, I am not using a USB for the ISO image. But I will try your second tip and see if it works. Thanks for the help.

Unfortunately, I tried your second tip and it did not work... I tried doing it three times and it kept on repeating the same error.

I was afraid of that, I think you'll need the USB solution.

So I have to get a USB and download Windows ISO on that? Then run bootcamp from the USB and unplug USB when running windows installation?

Is there any other way to resolve this issue? I don't have a USB stick on me right now and I have been trying to resolve this problem for days now...

Wait, Windows 10 April update is an update, do you have Windows 10 already installed & running from Win10?

- After the Windows 10 install error, Mac automatically boots back to OS X.

- TIP 1: Unplug the USB Stick or USB Hard disk you were possibly using to hold the Windows 10 ISO image. It is possible that this has been the issue all the time, that Windows or Bootcamp get confused about too many disks being attached. So remove the disk or stick.

- Now Reboot the Mac by yourself.

- TIP 2: While Mac reboots, HOLD DOWN the ALT -key. This opens up an operating system / disk menu, from where you can select WINDOWS instead of pre-selected macOS. Use arrow keys and enter to select. Trackpad/mouse wasn't working at all for me.

– Your Mac now continues to reboot back to the Windows installation process. Turns out that this time the Windows install doesn't get confused about disks (or something), and installation goes like a breeze after that.
