Hi everyone... My iMac will not boot to the system drive OR the DVD (snow leopard retail) -- the disk spins up and then goes the Apple logo and stops. Whats going on? A bit of a background -- I was using visualhub to convert all of my MKV's to MP4's using two external drives -- apparently it was throwing tmp files on my system drive for fun. And it ate up ALL of my HDD space. It said I had 0K free. An error popped up about my startup disk and some tmp files and told me to repair the disk using the Mac OSX disk. Which I tried to do... But now it won't boot to the system disk OR the DVD. Please help! Thanks guys -- I appreciate it.
