  • Check your BIOS Setup to ensure Hardware Virtualization and VT-x have been enabled. Enable these, restart and test Hyper-V again.

  • That is strange. Try the two basic Windows 10 repairs. Open cmd.exe with Run as Administrator. Run first: dism.exe /online /cleanup-image /restorehealth . Then run SFC /SCANNOW . Allow both to complete, restart and test.

  • Then you now need to try a Windows 10 Repair Install from the Microsoft Media Creation Link. Use the second link , work through it and start with Keep Everything. See if Hyper-V works after. First make sure Virtual Box and VMware Workstation are not installed.

Summary: I am trying to setup docker to setup docker I need to enable hyper-v. DISM and SFC did not work.

First make sure Virtual Box and VMware Workstation are not installed.

Assuming not, do a Windows 10 Repair Install from the Microsoft Media Creation Link. Use the second link , work through it and start with Keep Everything. See if Hyper-V works after that.

Repair Install link (Microsoft Media Creation Link):

https://www.microsoft.com/en-us/software-download/windows10

Windows 10 is running, so click on the Download button (not Upgrade Button, select Run. This will launch the Repair and proceed normally.
