Enabling virtualization in BIOS and installing Hyper-V in Windows 8.1 Pro x64 causes boot failure in this model.
Even the latest BIOS F.51 unable to fix the issue.
Something todo with USB 3 firmware?
Just disabling Virtualization in BIOS fixes the issue and system boots but then hypervisor fails due to non availibility of virtualization.
Microsoft advice: Update firmware(BIOS)
