Installation hangpup 20.7

[klaus]

Hello,
I tried to install OPNsense 20.7 on a x86_64 standard system (AMD-four-core CPU, 8GB RAM)  without success. I tried it several times from USB and from DVD but the install script hangup and I have to power off the machine.
How can I proceed with installation?
Klaus
