I got an issue in Qubes OS R4.0 when I'm trying to install Windows 7 on a Standalone VM. The beginning worked well : the installation proceeds and the VM make a first reboot which works correctly. When I launch again the VM, the installation continues but the VM freezed when it comes to the second reboot.
If I kill the VM and restart it, the installation fails and I'm forced to delete the VM in order to restart the process right at the beginning. I tried three times and it's always the same thing. Are there some people who had the same issue ?
Regards.
Thank you very much this guide worked for me.
