Problem with Install VRA on Hyper-V Host is Failing

Viewed 409 times


An administrator may want to install a VRA on Hyper-V host and encounter a failure.

Root Cause

There are two possible causes for the installation to fail:

  1. Secure boot is enabled.

  2. A VRA was installed on the host and the zDriver wasnt cleared after previous uninstall.


After attempting a VRA upgrade, the VRA listing under Setup in the Zerto GUI will show a status of:

Upgrade Failed


In if Secure Boot is enabled, follow the below steps to disable it:

  1. Click simultaneously the shortcut Restart + Shift key.

  2. Click Troubleshoot → Advanced options → Start-up Settings → Restart.

  3. Click repeatedly the F10 key (BIOS setup), before the “Startup Menu” opens.

  4. Go to Boot Manager and disable the option Secure Boot.

  5. Save the changes and reboot.

Note: The disabling of the UEFI Secure Boot is only for a few minutes to install the VRA, once it's up and running you can enable UEFI Secure Boot again.

If secure boot is indeed disabled, there might be some leftover VRA drivers which have not been cleaned up. In this case, kindly engage Zerto Support for further assistance.
