This is my second attempt at posting to the board.
I have made several attempts to install Windows on 10.13.6 Updated on my new MacBook Pro.
The last attempt aborted after the Windows installation step with an error of being unable to update the boot sector. I disabled SIP and T2 boot limits, but that did not change.
Did this work for anybody? How?
WinClone also failed.
My colleague found a Windows 10 x64 version 1803 that works. Install Parallels and download a Windows 10 ISO using it, in other words, download the Parallels Windows 10 ISO. We used that ISO in Boot Camp on two separate MBP 2018 i9 successfully.

I did the install yesterday on my MBP 15" 2018 using boot camp and it went without any problems. Since I did the install on the internal SSD I did not have to disable any T2 protection. I did not use a USB bootable media but a windows 10 Pro 64 Bit ISO file downloaded from Microsoft. I did also an install on my neighbor's MBP 13" 2018 but on an external Samsung T5. This worked also fine but since it was an external drive I had to disable Secure Boot and allow booting from external drive in the Startup security Utility. I would suggest that you remove the boot-camp partition and create it again. If you are installing on an external drive then reinitialize it. You need to have a GUID partition scheme with a 200 MB EFI partition formatted as fat32 and a windows boor partition formatted as NTFS. In any case reformat the EFI partition using diskpart in windows. Also try a fresh ISO downloaded form Microsoft.
W10 1607 would not work correctly on 2016/2017 Macs. I have 1803 working on a 2017 model.
1803 supports the T2 better than any previous release based on my testing on 2018. FileVault causes more issues than the T2 chipset.
I used 1607, which had worked on my previous MacBook Pro. Newer versions failed to install on the USB stick.
After completing install and setup, I upgraded to 1703. Some folks have reported trouble running with 1803, so I am holding off.
This is working well. I also booted it under VMware Fusion. On High Sierra and Mojave, you have to disable SIP for the first run.
Upgrading Windows under VMware resulted in the non-bootable standalone version. So I did this twice.
If you have an externally bootable drive or flash, try this.
- Go to Recovery (CMD-R on boot) and load the Startup Security Utility
- Enable External Boot
Reboot and see whether that disc can show up in StartUp or with Option Boot. If it replicates my issue, despite the setting in Startup Utility to "Allow booting for external media," the T2 bridge refuses.
Disconnect all external peripherals, run SMC and NVRAM Reset, use the ISO on the macOS internal disk. Do not mount the ISO and it should not be in the Downloads folder. Now retry BC Assistant.
I do not recommend anything older than W10 1803 on the 2018 Macs.
Disconnect all external devices, run a SMC and nvram reset, and try 1803.
Can you use a standard retail ISO from Microsoft Download Page?
Do you perform a regular install using boot camp on the internal Mac ssd ? Usually this error indicates an issue with the partition scheme
Which W10 release did you test? Upgrading to a newer release of macOS can also provide firmware updates. If you downgrade back to HS, can you install W10 correctly?
I was able to install from Mojave.
This one helped me, i was able to install with 1803 iso from microsoft tool.
Re: Boot Camp error: An error occurred while copying the Windows installation files
I've tried to install with bootcamp help. Tried to disable t2 protection, install with usb bootable media, first aid on Disk Utility, nvram reset. Nothing changed. "windows could not update the computer's boot configuration" error at the end of installation. A week ago i've installed another macbook but that one is 2017. Problem with Macbook Pro 2018 13
I have made numerous attempts with all the usual remedies - SMC and NVRAM reset, different versions of Windows ISOs, consolidating all my APFS containers to the original one, T2 security enabled and disabled, etc.
Could not get it to work - always the same error.
Of note:
T2 Security cannot be disabled on my system. It shows as disabled in the Recovery utility, but I cannot boot. External drives. They simply do not show in Startup or Option boot.
My hypothesis is there is a problem with the T2 security system. BootCamp Assistant must set an exception to write the boot info outside the Windows partition and this is getting blocked.
Since I lost one system trying to do a full recovery I will not do that and just wait for an update. Meanwhile I will have to make a trip to the Apple Bug Reporter.
