My Imac g4 will not go past the blue screen. I have tried everything. Unplugging, will not boot up in safe mode, command r. You name it I have probably tried it. My boss gave me an imac (8.1?). Can I use it as a host to try and boot the other one. I have not done this in a while and just need to get to some of the files on the G4. Thanks for your help.
