Formatting the hard drive while in the laptop
OK, so I have a 500GB hard drive in my laptop, I partitioned it and I put 80GB for Windwos and then the rest of it for MAC, I don't know how but I somehow got rid of the Windows. I ejected the BOOTCAMP on the Desktop of the Mac OS X and then I tried to delete the partition but it didn't work. Now I tried to go to BootCamp Assistant but It doesn't show that I have partitioned hard drive. It shows me that I have only 420GB and it shows only my Macintosh HD. The 80GB are lost somewhere. Tell me how can I format the whole hard drive and get the 500GB again? And i want to do it while the hard drive is in the laptop and is working? Is there any way of doing that(it is fine if i have to install the OS again) Or what do i have to get done so that I can fix it?
