Hey Guys, I have been at this for hours and stupid me I deleted some var and usr files while I was cleaning out my computer and now it gives me the kernal panic everytime I restart. Another problem is my cd drive is dead. this is what I have tried so far. Command + S and gets stuck at System uptime in nanoseconds: 787865735 Holding C Holding D, But not a hardware problem although it says that it is not supported. PERM reboot So I wanted to know what options I have. Is there a way that I can do it using a USB? Do I have to reinstall it that way and if so how? I am at loss for words. I have read alot of threads and I guess my problem is not frequent enough to pop up in just a 3 hour search. All post are GREATLY APPRECIATED. Its weird how appreciative a person is when truly in need of help. Thanks a Bunch Guys and Gals.
