Bonjour,
 
J'ai un problème avec mon ACER aspire 8930, il m'est impossible d'activer la virtualisation afin d'utiliser VMWARE pour mon travail, je suis allez dans le bios mais celui-ci est un insydeH2O (donc bridé...), j'ai fais la mise à jour du bios pour voir si l'option à été activer par la suite mais non..
 
En gros mon processeur supporte la virtualisation matériel, l'option n'apparait juste pas dans le BIOS....
 
J'ai trouver ce tuto pour l'activer sur le net mais le vtenable.py m'affiche une erreur, savez-vous comment régler ce problème svp ??
 
voici l'erreur :  
 

Code :
  1. Loading BIOS...
  2. Loading VSS...
  3. Traceback (most recent call last):
  4.   File "vtenable.py", line 85, in <module>
  5.     raise ValueError("Invalid VSS signature" )
  6. ValueError: Invalid VSS signature
