I install virtualbox 5.0 in Windows 8.1 and running smoothly, but after I upgraded to Windows 10 my virtualbox could not detect any network adapter. I've tried to reinstall virtualbox with this way Installing VirtualBox Guest Additions on Windows 10?, success but after I reboot my laptop virtualbox could not detect again. Please help me :( thank you
What guest OS's do you use? I use Windows 10 and my guest OS's are connected. In your guest settings (Virtualbox), go to network adapter, and set the attachment to NAT. If your guests are Windows 7 or later, then set the adapter type to "Intel PRO/1000 MT Desktop" and check "cable connected". My XP 32-bit guest's adapter type is set to PCnet-Fast III.
