Windows Disks Showing Offline After Restarting

How to fix secondary virtual disks that show as offline after restarting a Windows VM imported into VergeOS, using the Set-StorageSetting PowerShell command.

After importing a VM into the VergeOS platform, some (virtual) disks may not come online after a restart of the guest VM.

Beginning in Windows 2008, Microsoft added a setting for the default state of additional (non OS) disk drives. Occasionally when restarting, Windows may detect a hardware change, which is more likely if the VM was imported from an alternate hypervisor. When windows detects a hardware change, it may not bring secondary virtual disks online automatically. To change this to the recommended setting run the following Windows PowerShell:

Set-StorageSetting -NewDiskPolicy OnlineAll

Additionally, this can be done from the command line using diskpart or from Disk Management.
