Boot Camp Assistant not rebooting into windows install

[w_aldo]

Hi guys,

I have installed Windows on my MacBook (Mid 2014 Pro) before, and had no problems. I decided to completely wipe my Windows install since I wanted a fresh copy installing, but now when I try to re-install with Boot Camp Asssistant, it reboots, shows the Windows logo, goes black, and restarts into MacOS.

I have tried holding the option key on start-up, and booting to the Boot Camp partition (which obviously doesn't work, since it's a blank partition), and also the EFI boot, which shows the Windows logo, goes black, and restarts into MacOS.

I have also tried wiping my USB drive and going through the whole process again, but this doesn't work either. Is this a bug with Big Sur? I'm running Version 11.1.

No. Doubt it.

If you wanted to "factory reset" Windows, you should have done it within Windows, using Recovery option to do a Reset, with option to wipe out everything.

Learn about the recovery options in Windows. Find out how to reset your PC, go back to a previous version of Windows, or use media to reinstall Windows.

You probably just wiped the Windows partition but left the supporting bootcamp partitions there.

The fix:
- Boot into a USB Windows installer and install to Windows partition that was wiped.

Any problems present on your current install are more likely to persist after a "factory reset" within Windows, in comparision to a fresh install. I'm speaking from experience.

Additionally, I was running Windows 10 1809 - which means a "factory reset" would still restore to 1809, requiring me to install over 2 years of Windows updates - no thank you, I'd rather start a fresh with the most recent version.

All Boot Camp partitions were removed, only the MacOS partition remained.

The fix:
- Boot into a USB Windows installer and install to Windows partition that was wiped.

This is not the solution - the same problem occurred when trying this. It is almost certainly a bug introduced with Big Sur, as after 3 or 4 tries, it finally booted to the installer. However, even now that Windows is installed, sometimes after booting to the Windows desktop, the Mac will restart itself once again and boot back into MacOS (seemingly the same behaviour as when trying to install Windows).

It works now, unfortunately it is unreliable.

You are doing it wrong.

If you download the windows create installation media tool and run that, it will offer to upgrade to latest version available. From there you can do reset this PC - boom!

Nah, doubt it from your 1st post. Not clean, you should have used Bootcamp assistant to remove everything clean.

Nah, this is the mess you did by wiping Windows partition(s) manually instead of using Bootcamp assistant.

Oh well, I suspect only a complete redo will get a reliable, stable bootcamp setup.

Still does not solve the problem of existing issues still persisting to the "fresh" installation. Almost everyone competent in technology will agree that freshly installing software is the best practice. I have re-installed Windows using this method on multiple Macs (and PCs) in the past, and it has been flawless.

Exactly what I did. I also confirmed that it removed everything by opening Disk Utility and checking there too.

Again, I used Bootcamp assistant to remove the existing Windows partition. Where in my post did I say I removed them manually?

Clearly you much prefer the act of sounding smart on the internet, rather than actually helping people.

Lol, and yet you have problems as per 1st post.

Oh well, good luck.

I had my Mac restart into MacOS twice - weeks ago- I made sure Windows was selected in Startup. Haven't run Mac or updated to 11.1, thinking waiting a month or more.

Brand new Intel Mini, Big Sur 11.01 and downloaded ISO from Microsoft which BCA easily used. I was surprised the install initiated automatically on its own.

Predictable comment, so are you implying that it's impossible for Big Sur to have problems? You've forgotten that Big Sur was bricking certain Macs - specifically the model I have, only just last month.

Could it be the fault of the boot camp?Because it does not work sometimes.

I searched Google for the reason why the Boot Camp Assistant tool does not work, and at the same time Google recommended this to me.
