Windows Boot Crashes[edit]
If you find that OpenZFS is crashing everytime you boot Windows, you can remove the kernel extension part.
Enter the recovery CMD shell - you can use boot media as well
- When booting, once you get to the spinning dots part - turn off your PC - either by holding power button for 10s, or cutting power.
- Doing that 2 times in a row, Windows will ask if you have boot issues.
- Enter Troubleshoot, Advanced Options, then Command Prompt.
Remove the driver
- Navigate to your hard disk, which might not be C: during boot command console. Change drive letter, and issue "dir" until you recognise your disk.
- cd into Windows\System32\Drivers
- delete or rename openzfs.sys
- exit command prompt
- use menus to boot normally.
If you get access denied when you want to rename the drivers (fileowner is trustedinstaller)
- take ownership (current user) of openzfs drivers: takeown /F \windows\system32\drivers\open*.sys
- extend permissions (ex user administrator): icacls \windows\system32\drivers\open*.sys /grant administrator:f
