So my MBP 2019 has been perfectly working with my eGPU RTX 5700 XT for over a month.
Windows has somehow snuck an update in somewhere and now its BSOD - Critical process died. Cant get safe mode to work or anything.
I now begin the laborious task of deleting and reinstalling bootcamp and sorting out all the drivers, updates etc.
Does anyone use any particular program to backup bootcamp to an image that can be restored if this happens? Or is the windows feature usually the way to go and store it on an external HD?
My Bootcamp has always been unstable even before I started with my eGPU. Tonight i contemplated buying a windows laptop to use with my eGPU instead or building a mini ITX. Just seems mad, when my MBP works, its perfect for me! I just want stability! 🙁
Any help would be much appreciated, thanks

I use winclone since it's the only thing people have recommended here... yeah there's a cost. But it has saved me twice now.
Also - if you have parallels - I've had good luck getting that to boot into safe mode when my mac wouldn't naturally boot to bootcamp's safe mode. I've fixed it a dozen times with parallels and then booting back into bootcamp with success.
I tried the vmware fusion just two days ago since they have a free home user license now, but couldn't make it work reliably with my already working bootcamp...
For windows - I use Veeam's free backup software so I can restore individual files since winclone cannot do that without extracting everything first... and it's annoying. I'm guessing you could probably boot off of Veeam's custom recovery ISO it creates and restore bootcamp that way too - but its not specifically made for bootcamp like winclone is.
@erik_tank, Perfect! THank you for the great info

I am using Windows 10's System Image, Backup and Restore (Windows 7), and System repair disc.
I have used these for rolling back after Windows 10 update multiple times over the years without problem.
