Update (September 9, 2021): Microsoft released Windows 11 Insider Preview Build 22454 to the Dev Channel. My attempts to install 22454 were the same as my experience below with attempting to install Build 22449.
When Windows 11 Insider Preview Build 22449 was released on September 2, 2021, I got a Green screen DRIVER_PNP_WATCHDOG error on many installation attempts.
disabling IDE in BIOS
changing IDE/ATA controller driver from Intel(R) 500 Series Chipset Family SATA AHCI Controller to generic Microsoft driver
switching to beta channel, installing 22000.176 then back to the dev channel and attempting to install 22449
disabling all non-MS services in msconfig
None of those made any difference. I had 2 USB 3.0 external drives connected and when I disconnected those, the installation of 22449 was successful.
I had the same result doing a clean install with the 22000.132 ISO and updating to 22449.
The motherboard is an Asus ROG Strix Z590-I with an Intel Core i7-11700K. The Bluetooth driver is Intel Wireless Bluetooth v126.96.36.199. The IDE ATA/ATAPI controllers are Intel(R) 500 Series Chipset Family SATA AHCI Controller v188.8.131.523.
Attempting to Create a system Image would bring up the dialog box, “Where do you want to save the backup” and it would fail with another dialog box with the text:
“Windows could not find backup devices on this computer. The following information might explain why this problem occurred:
Close Windows Backup and try again.”
I searched the Windows Insider Feedback Hub, googled the web and Microsoft forums and I didn’t find a solution until a few days ago. On the Feedback Hub, in a post with the title, “Cannot create System Image in build 18956 FIX IT!“, CJH suggested disabling Windows Sandbox and virtual machine. (This link opens the Windows 10 Feedback Hub)
After disabling Windows Sandbox (Control Panel/Programs/Turn Windows features on or off/Windows Sandbox) I was able to create a system image again. I initially disabled Hyper-V Manager but after re-enabling it, system image still worked.
I try to keep up with the latest Windows and macOSs by participating in the Windows Insider Preview program and the Apple Developer Program. I run both of these OSs on a Macbook Pro Retina (mid-2012). As of today, that is Windows 10 Build 16232.1000 and macOS 10.13 beta 2 (17A291m).
A lot of the time, things don’t work because I am running beta OSs with released apps.
One of the recent problems I encountered with macOS High Sierra (17A291j) was a kernel panic when I was using Paragon NTFS for Mac 15 with Dropbox (v30.3.14). I don’t know if it’s a good idea, but my Dropbox directory for both Windows and Mac is the same directory on an NTFS volume. Every time I started Dropbox, I would get a kernel panic. I opened a support ticket with Paragon Software and a few days later they sent me a new version that had the same problem.
For interoperability between the two OSs, read/write capability really helps. In the macOS (High Sierra), NTFS read/write capability is not native. I was very happy with Paragon NTFS for Mac 15 until I started getting kernel panics. On the Windows side, I haven’t found something that will read the Apple File System (APFS) in macOS 10.13.
With earlier versions of MacOS, I had used the open source NTFS-3g. When Paragon NTFS for Mac 15 stopped working in my situation with Dropbox, I decided to try the commercial version of Tuxera’s NTFS for Mac. This seemed to work ok until I installed the macOS High Sierra Developer Beta 2 Update 1 (17A291m).
On booting macOS, I would get the error message:
Aligned I/O enabled.
/System/Library/Filesystems/fusefs_txantfs.fs//Support/10.9/tufs/tufsfs.kext failed to load -… check the system/kernel logs for errors or try kextutil(8).
the MacFUSE file system is not available (71)
I traced this error to Gatekeeper in macOS 10.13. After I allowed the software, Tuxera NTFS for Mac started working again.
