Mac OS Bootcamp Issue - Its there, but then its not...

[WelshDdraig]

Hey everyone - really weird one for you today.

 

So I have my Macbook Pro 2017 bootcamped with Windows 10 Pro and it was working fine yesterday - then there was an Apple softwware update for Bootcamp on Windows (which I installed) and all was fine until I rebooted.
My Win10 bootcamp was now stuck in a boot loop.
So I restarted into Mac OS to delete the partition and re-bootcamp. Which worked fine for a second - then the system restarted and went to boot into Windows to continue the setup. Got to the Windows logo and it all went black and went back to Mac OS. The partition was in Disk Utilities, however, the Boot Camp Assistant could not see it and on restart (while holding down option) it was not in the boot selection at all. 
So I repeated the steps of delete partition, re-bootcamp etc to no avail. It just doesn't work anymore.

Any advice would be greatful

 

Mac OS is Catalina 10.15.14

oof, you shouldn't have done it like that... you could have just fixed the bootloop. regardless i don't know a quick and easy way of fixing this either.

Eh, I didn't mind removing the partition. I run everything and all my programs via USB storage as I only have 50GB for Windows (128gb SSD in total).
Might give it another go but with it installed on an external drive.

ooooof

 

have you considered a virtual machine with the virtual disk on an external drive? that way you have all your storage for macOS.

You don't mention what version of windows 10 you used to re-install? Presume it was the latest iso at version 2004?

Regardless,  if this was my machine, I would have done the following...

 

1) Removed bootcamp by running bootcamp again and using the restore option 

2) Download the very latest 64bit ISO from here...

https://www.microsoft.com/en-gb/software-download/windows10ISO

 

3) Re-test by installing the latest ISO using bootcamp

Yes, Yes and Yes, it's really weird. 

It's there for the first boot as if to continue the install, then it crashes - boots back to Mac OS and then its no longer in the boot menu, but the partition is there in Disk Manager.

I have as I did have a VMWare Fusion license from my university course, but with the specs I have, virtualization just doesn't seem to be optimal (2c/4t i5 and only 8GB of RAM - wouldn't share well with host and VM).
Its not the end of the world - I still have Windows on my Desktop, its just nice to have it portable as well (in case my family want to use it - they have never used Mac OS before - side note: I'm actually trying to convince my mother to get a MacBook or even and iPad as all she does is use Facebook, access her work schedule so something that lightweight and easy to use would be great for her).
