Hi folks, could do with some help. I have just bought a Firewire drive, and want to be able to boot up from a clone on that drive. I have a MacBook Pro 1.83GHz Intel Core Duo, running OS X 10.4.11, and an Iomega 750Gb Firewire 400 external drive. I'm using Intego Personal Backup X4 to produce a clone of my internal hard drive, a Western Digital 320Gb replacement. I have no problem creating a clone with Personal Backup X4, but I am unable to get the laptop to boot up from the clone. I have the laptop switched off, the external hard drive switched on and connected, switch the laptop on and keep the c key pressed, but every time it boots up from the internal drive, with no choice of which drive to boot from. Where am I going wrong? Thanks in advance, Effortless.
