Hi....Unfortunatly I am not familiar with GAG or the NT bootloader as far as a dual boot with LINUX. I know, just from my experiance with KNOPPIX, if you just use the regular installer, knx2hd, you will be prompted to setup LILO, but you have to configure it later by using KWRITE, or any editor to recognize and show you your boot options, as far as choices between Windows, Linux etc. Anyway thats how I did mine.
