So, as we have successfully prepared the Windows 7 installation file on the Opsi server, we have a client boot. A newly purchased or existing PC, a candidate for Windows installation, can be embedded within the opsi-configed Web site, the Clients tab, as a PXE (pixie) client. The client must have BIOS support for boot through the network. If we set the first choice of PXE in the BIOS client, it should automatically locate the Opsi server on the network. In our case, since we use an "external" dhcp server, we find Opsi server clients "manually" with the help of opsi-client-bootcd.
