I rang apple support as I was having problems eg spotlight was a bit flakey and there was an alias in the bin that I could not get rid of. I was advised to reinstall hed down the ctrl key with dvd in place . . ."that's it" the apple guy said "you'll need disc 2, bye!" and I was left alone! It installed then restarted and asked for disc 2 . . .but the dialogue box was greyed out. I ejected disc 1 after a while and inserted disc 2. it ejected it . . .7 times. I rang apple . . . . closed till Monday! I tried again and there was no destination disc . . . So to my question I want to start up from a dvd so I can recover some items before I WIPE and start again. But it just tries to istall? Can't I start up from a dvd like the "cd" icon above "hd" icon?
