According to Alex MacLeod: >Can anyone help me..... I really need help. >Thanks >Alex Alex, Power down the Ti-Book, insert the proper CD Installer. Turn power On, and then press and hold Option - Command - Shift - Delete all at the same time. This will force the Mac to bypass the primary startup volume and search for a CD or external drive from which to boot. Just press and hold. Let us know what results you get. Oh, and after you boot, Erase the drive using the utility on your Installation CD. ~flipper
