Hi, I have a Macbook that was performing a pretty huge software update when my brother unplugged the power supply for some idiotic reason. It now takes about 3 minutes to get to the login screen and after that it won't load anything else. The CD drive on it is trashed, so I hooked it up to my iMac via Firewire and booted it in target disk mode to reinstall Snow Leopard. I open the installer, and it says that it will take 1 hour and 4 minutes to boot. After that, the bar stays still and won't move. It won't let me cancel the installation ('removing installer support files'), and I'm at a loss of what to do. Can anyone help me, please?
