I have an HP Envy 15-j101ex laptop. It is running Windows 10 Pro 64 bit. It has the latest BIOS from HP: Insyde F.65
I need to turn ON Hyper-V (hyper-V Hypervisor) to create some virtual machines. So I have added the Windows Features (turned on in Control Panel Add Windows Features): Hyper-V Platform and Hyper-V Management Tools.
For the Hyper-V Hypervisor to work, Hardware Assisted Virtualization needs to be turned ON in the BIOS. The laptop does support Hardware Assisted Virtualization. But when "Virtualization Technology" is enabled in the BIOS (with UEFI enabled), this ends in a boot freeze with the rotating circle (under the HP logo) and the laptop never starts up. Virtualization Technology has to be turned OFF or the laptop will not boot up.
I have checked the Microsoft site and ran the tools suggested: coreinfo.exe, SLAT status check, DEP checked. Everything on the laptop is as expected in the requirements for Hyper-V.
Any suggested fixes?
Note: I have seen suggestions to disable Bluetooth and uninstall the driver. But if I uninstall Bluetooth drivers, Windows automatically reinstalls the Bluetooth drivers after a restart. And if the BT device is just disabled in device manager (without drivers uninstall), the problem (failed boot) still occurs.
