It does not boot in safe mode.
I have been having this problem for almost 24 hours now. Yesterday I was able to reboot in safe mode once. After I rebooted in safe mode , I restarted the laptop since then. I was never able to reboot the machine even in safe mode. I am very frustrated at this point.
Also I tried to reset the NVRAM, (Command, Option, P, R) the problem is still there
I don't have installation disk with me. Is that the solution.
This is very frustrating
Re-installing is not helping or solving the problems.
