Error on install

[IlarioQ]

Hello everyone, after a short experience with zeroshell I would like to try opnsense. I burned the dvd version but I can not install it, at boot the dvd appears this msd error: cd0: Read 1 sector(s) form 16450559 to 0xfffe000 (0x8000): 0x32 on the telegram channel they tell me that it is because of my pc too old, but on the same pc I can install opnsense virtualized with qemu / kvm. Here the installation is successful but I do not know how to reach ip 192.168.1.1 that if typed from the browser of the host pc of the mv takes me to the other side. Do you have any idea why it is installed as a virtual machine and not physically on the same PC? Thank you Ilario
