Mac Won't Boot From Installation Disk
After doing a software update, my Mac Pro got stuck on the gray screen after restart (seems like a very common problem recently). I am able to boot into safe mode by holding shift (only works like 10% of the time) and verified permissions. It says I need to repair my disk, but i can only do this by booting from my install disk.
However, I can not boot from my install disk. It gets stuck at the gray screen every single time.
I have done everything recommended in this post with no success: https://discussions.apple.com/docs/DOC-3353
Am I screwed here? So irritated that this all happened because of Mac's own software update. I have wasted HOURS troubleshooting and it looks like my only option is to pay to have it serviced.
Any help is appreciated.
