Q: Computer Refuses To Start

My MacBook Pro won't start up. Every time I try to start it, it comes up with this message: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again."

Behind that is this error message (May not be 100% accurate--just a few characters were covered by the restart message)

panic(cpu 0 caller 0xffffff800053e12f): "Process 1 exec of /sbin/launchd failed, errno 8"@/SourceCache/xnu/xnu-1699.24.8/bsd/kern/kern_exec.c:3546

That is a kernel panic.

Looks like you have a very corrupted install of OS X.

Try booting into Safe Mode. Hold down the Shift key at startup.

It says to hold the shift key after hearing the startup tone, hoever I'm not hearing the startup tone whenever I boot my computer. When I try holding the shift key as soon as I start it up, it still won't boot in safe mode? Halp pls?

What model year is your Mac? When did you buy it? Did it come with Lion or Mt Lion pre-installed on it when it was new?

Then you can use the Onlin Internet Recovery system to boot the system from and do some drive verifying and repairs with Diosk Utility.

At startup hold down the Command + Option/Alt + r keys and keep them held down until you see a globe on the screen.

From the screen that loads use Disk Utility to verify and repair the drive and also do a Permissions verify and repair.

Nope. You need Internet access.
