I'm looking for some help. I have a Mac Pro that I purchased in August of 2008. Today I was trying to burn a disk in Toast and recieved an error. I hadn't rebooted my computer since installing a new hard drive last week, so I restarted it. When it was restarting, it sat at a white screen and I can't get any further. Thinking it may be an issue with the new HD, I removed it and tried to reboot it. No luck... After researching on the net, It looks like I need to do an Archive/Install. The problem is that I can't get my DVD drive open to insert my OS X Install disks. I've tried all the tricks I can find on the net including: - Holding down the mouse buttons while booting up - holding down F12 while booting - holding down the Options key while booting to get to the boot menu Can anyone suggest any thing else?
