I have a MBP and unfortunally the whole HD partition has been converted to NTFS and windows Xp has been installed on it. As much as i love windows i want to try something else. When i stick my new OSX disk in and hold "c" nothing happens, but when i stick a windows disk in or a linux boot , it boots to the disk. Also the Hard drive says its 114 mb Im not sure if the previous owner F"ed something up but how would i resolve the problem?
