our latest release 22.214.171.124 is installing even without internet (offline), you only need the 2nd cd. you'll need also permissions for firewall/router is pluto isn't your router.
but i guess your issue is related to hardware.
when you said it's rebooting, does pluto starts to load modules, or it's rebooting immediatly after bios?
if you get the nics after hardware detection, when doing networks setup then the nics are supported in linux.
