If I got this correctly from another
thread, OP uses 32bit Win10 build 10240 and Vbox v5.2.
In that case I see no chance for viBoot to run; 64bit OS needed.

Weird.
I got that file directly, even for another OS, if I click.
If you're on 32bit Win10, try to get the 32bit link from OneDrive there:

I don't use ImgBurn (since ages ago) but there should be a BlueRay or double-layer disk template somewhere to allow you to have more space for the image. There are many burning programs that can create ISO, another example is
AnyBurn.
Not sure I follow. But I did restored backup images in VMs before, so it should work, one way or another.
If you placed the backup image in a large ISO, this is usually not bootable.
You'll have to add another dvd-drive to the VM to boot from, be it Macrium / Aomei bootable rescue disk and select your image from the other (large ISO) dvd-drive in the restore process.
Example:
VM
- dvd-drive1: Macrium or Aomei cd.
- dvd-drive2: The large ISO with the backup image
- HDD-drive: where the image should be restored to
--> then boot from dvd-drive1.
