Boot Camp Issue: W10 keeps asking to Reinstall

Hi,

I recently purchase a new 2017 iMac (3.8gHz QC/8MB) and am trying to run W10 for gaming (F1 2018) but run into the same issue over and over again.

My steps:

1: updates it to the latest Mojave version

2: downloaded W10 ISO from the Windows site (followed link from Apple’s BC page and picked the older ISO version)

3: started Boot Camp and followed the installation

4: iMac restarted nicely into W10 and started the Boot Camp Assistant in W10 to finish the installation.

Here is where things went wrong I guess

5: the BC Assistant in W10 frooze so I rebooted the iMac and started from the W10 partition. The fact that the Boot Camp Assistant in W10 did not complete caused an issue with drivers not being installed properly because the game just did not run smoothly at all)

6: decided to boot back into macOS and remove the partition via Disk Utility.

7: for whatever reason the crashes my Mac, reboot and noticed some system icons like Mail.app went missing.

8: started another Boot Camp installation, let it run, started in W10, successfully was able to let the Boot Camp Assistant inW10 do its thing, installed the game and everything looked great.

However, when I restarted the Mac to boot into W10, i ended up with a blue screen telling me there was an issue ans that I had to reinstall W10 which I did. Installed the game, everything great intil the same sequence started again.

So a bit lost.

Q’s:

1: are the missing system icons a concern and could they cause the W10 issue?

2: what could cause the constant issue with me having to install W10 (reading about version 1703 being the only right W10 working)

3: what would THE right way to start from scratch? (Ideally erasing any W10 remains from previous installations.

many thanks,
