Hi, Had to reformat my hard drive for numerous reasons and set it as mac OS extended (journaled). I thought you could install to a fresh drive from a retail snow leopard disk by booting and holding c. After a few seconds a flashing folder with a question mark appeared (having done some research i think this means it is trying to find a volume to boot from?). I left this screen on for a good 30 mins incase it was just being slow to read it and i could hear the drive spinning during this time, but nothing... I have tried to install from both a snow leopard retail install and also the install disks that came with the macbook pro. Any ideas how to get an os on to the machine? (for info, I have another machine that I can target mode from). Thanks in advance.
