There are several suggestions I have when installing Windows in general. Windows tends to be larger than most Operating Systems (a Windows 10 VM is small at 30+ GB, while a LINUX install is normal at 15GB.

The less you do after installation and the fewer snapshots you take, the smaller the file will be.

If your image file is not up-to-date, immediately do a windows update.

When it is done it will automatically log you in.

This will look like a normal Windows installation.

Let Windows do a Custom Install to your VM disk (You can change the size later if you wish).

Put in your Windows activation code in the form of xxxxx-xxxxx-xxxxx-xxxxx-xxxxx.

For Windows, select Next and Install now.

Remember if using a Windows setup image to press a key when it says to press any key to boot from CD otherwise the time out message will appear.

Click Continue after choosing the boot firmware version (if given a choice).In the next Window, select the Operating system type, if asked (for some versions of LINUX, the software is unable to determine the version by scanning the image).In the resulting window, select the image file from your MAC.If you are comfortable dragging and dropping on a MAC - drag the image file here, otherwise, click 'Use another disk or disk image.Choose Install from Disk or Image and click Continue.Click the down arrow next to the plus sign in the default VMware Fusion window.Make sure the image file you are going to use to create the VM is accessible (I copied my iso file to my desktop).The process to make a virtual machine is relatively simple. The software is made for a MAC to run virtual machines (VMs).

This was fairly easy to do because of some software from VMware, called VMware Fusion. So I took the easy way out and created a virtual machine (VM) on the MAC running Windows 10, version 20H2. The problem was I either missed some programs or was not conversant enough in macOS to know which programs to use in their place. But, I got a new MacBook Pro and started to get it in working order so I would be able to be of use to him if he needed it. Since I was hired here over 25 years ago, the Director has always been a Windows person. Since he uses a MAC exclusively, I needed to get up to speed quickly on macOS. Our Cancer Center got a new Director back in October of 2020.
