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.

@LonerT?

many thanks,

Roland

Windows is offering a 1809 version on their site. Would that work or should I find an earlier version?

Sorry for the messy communications Loner. After the successful launch, I ran an Apple Software Update on W10 and noticed an updated Graphics Cards Driver. Could the old driver been the culprit?

Create a Restore point, before you apply updates from Apple Software Update.

Keep the BT mouse. If it does not work in Windows, you can connect the Wired mouse to get control.

Hi Loner T,

I might have to transfer the game's files. As said, the game worked perfectly and I was able to reboot into macOS, but the 2nd time it failed.

I also remembered that when I was able to get into W10 and saw the regular screen, it somehow rebooted itself into macOS and get an Error Message I recorded. Is it save to share that here? Or can I send it just to you?

I am willing to start from scratch but would like to know how to wipe all previous W10 traces?

Thanks Loner!

Mojave updated the EFI firmware, which results in MCA (Machine Check) causing this MCA dump. You can run SMC Reset (How to reset the System Management Controller (SMC) on your Mac - Apple Support) and test.

So it seems the CMS+NVRAM fixed the issue?

Could you explain in layman terms what fixed the issue?

It is good to see it work properly without peripherals. A SMC Reset rebuild the internal hardware database. How to reset the System Management Controller (SMC) on your Mac - Apple Support provides a much better explanation than I can.

The only thing that is not working is the reboot into macOS from Boot Camp icon in the task bar.

It tells me it can't find the macOS XYZ... (missed the message)

The AppleControlPanel.exe does not recognize the macOS APFS file system. It does work properly on 2018 Macs. There are various 'modifications' which will allow it to work. If you are interested, I will post links.

Next I will test with adding the USB Cable for the steering wheel and a USB C to Mini-Display Port cable to use my old 27" iMac as a 2nd screen.

Have a mild suspicion that the steering wheel maybe causing heartburn.

Does the other iMac support Target Display Mode? See Use your iMac as a display with Target Display Mode - Apple Support for reference.

Would love to understand what cause the issue in your opinion.

Connect one peripheral at a time, and let us see what we get.

Once the first W10 installation screen shows up, physically disconnect from all networks and test W10.
