Can you at e least get your hands on a Snow Leopard Upgrade DVD (29 $)? Or do you know someone with another Mac? I ask because, if the latter is the case, you can use Target Disk Mode to check your MacBook's HDD and see, if you might solve the problem without re-installing Mac OS X or if the problem is somewhere else.
yes i have I have macbook application install dvd and mackbook mac os install DVD
This happened to me the other day. What does it mean? I didn't think too much of it. I researched it and i figured out what it was but i don't know what it's supposed to mean.
A kernel panic is an action taken by an operating system upon detecting an internal fatal error from which it cannot safely recover. The term is largely specific to Unix and Unix-like systems; for Microsoft Windows operating systems the equivalent term is "Bug check" (or, colloquially, "Blue Screen of Death").
Then insert the first DVD and start from it via holding down "C" after the startup chime sounds and use Disk Utility to verify your HDD or even repair it. If that does not work, use the Apple Hardware Test.
i inserted the application DVD but when i hold down "C" after the startup chime sounds . nothing happens im seeing the same Grey screen .
Sounds like hardware failure. Either the RAM, motherboard, or something wonky. I'd take it to an Apple Genius.

one last thing i have boot camp on the macbook and the windows side is working perfectly .
Well then take my previous advice and start in single user mode (hold command S while the system boots) and try to fix things from there.

disk repair failed any suggestions ?
fsck -fy
reboot
that sucks. Did you do it from single user mode, the loaded OS, or a boot disc?
Disk repair with a loaded OS isn't going to do much so you either have to do it from a boot disc or single user mode.
hold command and S when the computer is booting. Wait for everything to load. At the prompt type
followed byCode:fsck -fy
Code:reboot
I just had to format the HD and install a fresh copy of mac os x 10.5 .is it important to install the latest mac os X ie 10.7 ?
