Mac won't automatically restart to Win10 even if it is default start-up disk

[fasttrackstatus]

Hey guys,

Ive scanned the forums but just can't seem to come up with an answer to this. I often use these forums to troubleshoot issues but have never had to post myself as usually find some out there has already had the same issue before and posted about it, but not this as far as I can see! It's really bugging me so I hope you can help!

I have a MacPro (2019, OS Catalina v. 10.15) and am currently running the latest version of Win10 on a second partition. All bootcamp drivers/software were up to date when I installed around one week ago and everything seems to be running smoothly EXCEPT...

Whenever I restart my laptop, it makes sense for me to automatically boot in Windows, as from the windows side its easy to choose to restart to OS through the grey BC diamond icon in the taskbar. So the only time I restart in OS, it would be to access Windows. However, despite selecting the Windows partition in Start Up Disk as default, and "you have selected Windows on the disk 'Bootcamp'" dialog appearing (and the windows partition appearing on the left), the computer still always boots to OS, unless I hold down the option key and choose a partition manually. I have also selected the windows partition to be the primary boot drive from the Windows side, and used the key shortcut (I think its command or control click, can't remember right now) to select the default start-up disk from the selection that appears when option is held during booting up...but still, same problem...

Has anyone else come across this problem? There must be a solution out there, right? Its particularly weird as the issue seems to be on the OS side, so it doesn't seem like a weird windows driver glitch during the bootcamp install. I spent quite a while getting everything to run as I like it (password-less sign-in on the Win side was quite an adventure to implement for some reason..), but I just can't figure this one out. Filevault is disabled, not sure if that's relevant.

If its really unfixable, one workaround I thought of would be to have some kind of "restart in bootcamp" icon on the desktop. Far from ideal, but maybe doable?

Thanks in advance.

If you experience issues related to these settings or others, resetting NVRAM might help. For example, if your Mac starts up from a disk other than the one selected in Startup Disk preferences, or a question mark icon briefly appears before your Mac starts up, you might need to reset NVRAM.

Reset NVRAM on your Mac - Apple Support

If one or more settings stored in NVRAM don't work as expected on an Intel-based Mac, resetting NVRAM might help.

Thanks for the tip but unfortunately I already tried that too and it didn't help. Today I was experimenting further and found its slightly more complicated than I first thought and may in fact have something to do with the windows side:

If I select bootcamp as the start-up disk, then restart, it restarts in Win just fine. The problem starts from the first time I "restart in OS" using right-click on the diamond bootcamp icon in the task bar. As soon as I do that once, the computer will always boot to OS by default, despite the windows partition still being the default in options. If I re-select the bootcamp partition and then jump between the two sides using the classic start-bar/power/restart option in Windows or the apple/restart in OS, it restarts in Windows as needed unless I hold option. The problem only starts after I have restarted once using the option through the diamond "bootcamp" icon.

You may say 'just don't use the bootcamp restart shortcut", but the point of this is that if its running how I want, I will never have to waste time holding down the option key. From OS it will boot to windows and from windows I just click the "restart in OS" option. On the boot option screen, it hangs there for a while looking for networks, which is even more annoying and time-wasting - any way to at least turn off this network option so it only scans the two physical partitions?

just giving this a bump as surprised no one has encountered a similar issue, maybe it got lost during the festive madness...

I never used Taskbar shortcut in 14 years, never had trouble, never tinkered, going back to Vista 7, 8, etc. on Mac Pro (desktop workstation) and 2015 MacBook. Always used control panels on both sides.

Been playing around with Windows startup services?

For some users and systems, the Bootcamp assistant and drivers are better in Big Sur. It use to be possible to download newer package independent of OS.

I also ran bootcamp on my previous machine since 2012 and never had this issue. Seems like a hassle to open up control panel just to restart, especially when the "restart in OSX" is right there next to the "open control panel" option..

Not particularly, though as start up services only start when windows has already started up I don't see how this could affect anything.

Interesting. Link?
