Always consult your motherboard manual or manufacturer's support resources for specific instructions tailored to your hardware.
| Symptom | Likely Cause | Solution | |---------|--------------|----------| | BIOS shows enabled, but OS says disabled | Fast boot / Windows Hyper-V lock | Disable Hyper-V: bcdedit /set hypervisorlaunchtype off + reboot | | VirtualBox error: "VT-x is not available" | Nested virtualization conflict | Uninstall Hyper-V, VBS, or Credential Guard | | AMD-V appears missing in BIOS | CPU doesn’t support (e.g., some Ryzen 3, older Athlon) | Check AMD product specifications | | Setting resets after power loss | CMOS battery weak | Replace CR2032 battery |
Before enabling hardware virtualization, confirm: hardware virtualisierung aktivieren
Steht dort "Deaktiviert", müssen Sie die Einstellung im BIOS/UEFI vornehmen. Schritt 2: Das BIOS oder UEFI aufrufen
