Hi Boopathi,

Please see the link and check the error codes.

Its likely a Vmware NIC driver.

Do you have the newest Vmware tools installed?

Hi,

Try to change the other ISO to upgrade.

A driver has caused an illegal operation.

Windows was not able to migrate the driver, resulting in a rollback of the operating system.

This is a SafeOS boot failure, typically caused by drivers or non-Microsoft disk encryption software.

If the error is caused by some driver, please do the following:

Open Windows Device Manager, and turn on the “View – Show hidden devices” option.

Investigate all the devices listed to find which device is using the problem driver.

Either update the driver or uninstall the device together with the driver.

Also I find some people disabled vt-d setting in bios.

Intel VT-d in BIOS under Advance-Setup->Chipset and Legency USB-Support under Advance->USB.

Hope it could be helpful
