In the Internet menu, select "Set IP address". I'll assume you're using a wired ethernet connection. Select "eth0" at the top, then manually put your IP address, subnet mask, default gateway, and DNS servers... Copy the relevant information from an "ipconfig /all" while booted in Windows, this will be the easiest way to obtain this information. Once this information is inputed and applied in BT, you should be able to access the Internet no problem. Depending on your chipset, you may have to modprobe the driver.
