Okay, I have a serious problem with my macbook. I'll begin from the start. My macbook has never had a single problem until today. I bought os x leopard today to install for the first time on my laptop. I restarted... everything was normal and I came to the screen which checks the disk to see how compatible it is with the computer. After about an hour, it was around 50% complete and I received a message telling me to clean the disk and try again... Anyway it wouldn't allow me to access the disk, it only rebooted itself and then returned to the installing process. Again, which took around 3 hours to install, which I've heard isn't normal. I went out for a walk to kill the time and came back to find my macbook with my previous wallpaper and mouse icon and no applications. I clicked around and eventually everything began to show up. The os x leopard intro movie played, not full screen... if that matters?, and after it had finished I tried to click on some things on the desktop but they would be open. Apps like safari opened and worked fine, but I could not shut down my macbook or restart. I downloaded upgrades and clicked on the "Restart Now" button, the thin bar on top with the apple logo disappeared but the system did not restart nor shut off. So I held the power button until the system went off. I turned it back on to find the computer boot up and bring me to a registration screen. After filling out the registration info slots and clicking "Done" the registration screen would load up fresh again. There were no other applications and I couldn't restart or shutdown the computer. I had to enter safety mode and click the back button and restart that way. Then the computer opened and worked like a charm... until I tried to partition 25 gigs for boot camp. The partition process was taking around 2.5 hours, which again is not normal, so I exited the program and guess what? 25 gigs are missing on my harddrive now and no the partition was not fully installed. So... I realized that there are new software updates available... I download them and click restart... and guess what? Neither restart nor shutdown work. I run tech tools and it tells me the volume structure has failed. I would like to thank you for taking the time to read this, and I am very... VERY grateful for anyone who can help me. Please.
