Windows 10 fails to install on my Intel MBP

[MathewNM]

Hi,
I have this problem that bothers me for last few days and at this point, I am really desperate about it. I have MacBook Pro 13 from 2019 and for some unknown reason I am not able to install the Windows. I downloaded official Windows 10 ISO from Microsoft website, launched the bootcamp assistant and everything went good until the installation was almost done.

Then a message which said ,,windows could not update the computer's boot configuration installation cannot proceed,, showed up and after that the computer booted back to the MacOs.

I tried PRAM reset, turn off the Secure boot, different ISO and nothing seems to work for me. And now after I turned off the secure boot its even worse, because when I try to install the Windows now, every time after I accept the Terms and Conditions of Windows, instead of installation it directly reboots to the MacOs. I turned the secure boot on again, but it doesn't help. Could someone help me out?
Thank you in advance

Without knowing which version of macOS you're running, there are three (3) reasons I can think of...
a. You're running FileVault.
b. You haven't yet run Disk Utility under Recovery Mode.
c. You're likely running Big Sur (!!!) or earlier so it's time to upgrade to Ventura.

I've literally had this happen off and on for YEARS (started using Parallels prob 10 years ago... if it was even around back then... it's been a while lol). Until quasi-recently I kinda expected to have to reinstall macOS at one point if I was doing Parallels installs for my 3x Mac's I own (at least one of them would brick and only thing I knew how to do was a fresh macOS install, then Parallels worked nicely).

Bad news I know, and wish I could help more with a real/better option, but had this happen probably no less than 5-6 time through the years, and that's how I always made it work. Thankfully it's been WAY better for like 3ish years...

Long story short you should never use Boot Camp Assistant whenever possible. Use this guide to do everything manually, you'll be good.

Let's start from the beginning.

Let's ensure you actually have an Intel MBP, as silly as it sounds, if it is the Core-i9 modal cool.
Your Windows 10 image: Where was this sourced?!
^ This is crucial and should NOT be downloaded from any forum PERIOD!

1. Get the official Windows 10 or 11 ISO image directly from Microsoft:
You'll need a Windows PC to begin with ... if you or family/friends/employer do not have one - or on the later restrict you from writing to USB get to a BestBuy or computer shop to begin.
Goto:
download Microsoft's Windows 10 installation media software using this official URL: https://www.microsoft.com/en-us/software-download/windows10

download Microsoft's Windows 11 installation media software using this official URL: Download Now

Use a USB stick of 16GB or larger (larger not really needed).
Links above are to create a BOOTABLE USB Media stick for Windows installation. Depending on the VM you choose you may have an issue getting this installation to work (VMWare Parallels both should work, but for that free whatever-Box thing maybe problematic, I cannot recall the name).
NOTE: Windows 11 is 64-bit ONLY, while Windows 10 will give options to install 32/64-bit I believe (if you google search and use the ISO download links you can use Windows 10 32-bit but not ideal).

NOTE 2: for Windows license you'll need to provide the OFFICIAL key for that to work! Old methods of cracking etc will not work and no further discussion here, nor via PM or not he boards SHOULD nor WILL be discussed.

Ensure you hav the latest macOS updates for the macOS you're preferring to use, and for BootCamp use the latest available. Save, Save, and SAAAVEEEE your work and reboot before installation.

Make sure Filevault is off otherwise bootcamp will crash.
