Hello. I note that I have already installed various Macs via bootcamp. Now I have a new macpro and I can't install it for anything. The default state is MacBook by default. I run the Bootcamp wizard, redistribute the disk using the scroll bar in the wizard. The supporting software will be downloaded. The installation of windows 10 starts (here it is strange to me that the installation does not offer me partitioning in windows, I think it offers it another time. I used the same ISO on a iMac a week ago). The installation will run almost to the end, but at the end it will say "system windows cannot update boot configuration, installation cannot continue" .macbook reboots but does not boot, black screen. It only helps to press the Option key and select the boot disk Macintosh, MacOS runs.
When I erase the disk and give a complete new installation (as factory setting), the same. Has anyone encountered this, please?

No ii did not allow me to select partition type, I was only able to select size during Bootcamp wizard.In Windows install it did not show me any partition manager (as usually during Windows installation).
Update: I have downloaded ISO file from Micrtosoft website and it worked, Windows are installed.It makes me confused, because before I was using my own iso file many times(even in bootcamp installation)...
