    This is a hypothetical question as I notice in the Mojave Developer Preview offers APFS only and the current High Sierra installation is HFS+. Would this affect the ability to boot in to Windows in Bootcamp or would Windows need to be reinstalled?

    High Sierra when installed on an SSD is APFS unless you force HFS+. On a rotational drive, yes, it’s HFS+.

    MacOS (regardless of APFS or HFS+) CAN see the Windows drive, so you can select it from the settings applet and restart to Windows from there as usual.

    The problem is that Windows, and bootcamp when booted to Windows, can’t see an APFS drive, regardless of macOS version installed. So bootcamp won’t be able to select your macOS drive to restart.

    In that regard, it will only be a minor issue. You can (if you have an EFI GPU) still use the Mac boot manager to re-select the macOS drive and boot.

    I hope that was clear, I’m a bit sleepy right now.

    Thank you so you would still be able to boot in to the Bootcamp partition by pressing the alt key?

    I installed Mojave a few days ago and my bootcamp partition still works fine. You'll be able to use the alt key to boot into it.

    Yes you can, that's not a problem at all. To boot into the BOOTCAMP partition while running macOS, you can also just go to Settings > Startup Disk > Windows > Restart

    Getting back to macOS is the issue but you just need to use the alt/option key to do that.

    I have a clean install of Mojave and am setting up a clean install of bootcamp. Is the experience different on the Mojave version of bootcamp, I mean has anyone else tried this?

    I am at ground zero here and can already see running Boot Camp Assistant in dark mode is a fail ...

    mojave beta 3 seems to fix the issue with boot camp assistant being unusable in dark mode.
    ...
    although now being able to use it i get a kernel panic when resizing the drive so i've probably hosed my entire drive. it still boots but since then now i get kernel panics on a regular basis. i used the 1803 build for windows 10.

    I'm having similar troubles.

    I can see the disc selection option like normal, but no matter which disk I click (Mac or Windows) it boots up Mac.

    Half my work is on my Windows partition! Help!

    Hi! I had the same problem. Only solution for me was to format the macOS-partition, followed by a clean install of macOS High Sierra. After finishing the installation, I could boot into Bootcamp again.

    I like mojave but I think I'm going to do the same thing. It killed bootcamp and my wireless card.

    I have this issue as well. To get around it, I had to do the following:
    In Mac, go to system preferences then select Startup Disk
    Click the lock in the bottom left corner (or don't if its already unlocked)
    Select Windows (Should be next to MacOS)
    Then click Restart

    Now your Mac will automatically boot to Windows on every restart so to boot back to Mac you must help the option key while booting up and select Mac from there.

    also i traced the source of the kernel panics. don't mix NTFS and APFS partitions on the same drive. i've only tested this extensively with NVMe drives, but it may possibly apply to other hard drive types. anyone who would like to go out of their way to test this then by all means.
