Hello, I have a Powerbook G4 500mhz, and the DVD drive wont boot from any disk i try, i checked all the connections and it seems like the drive just fails. It spins the CD's but it never recognizes their booting ability. I need to boot from a OS Cd so i can restore my hard drive, and i need this problem gone by the end of the week. If I had an external CD drive could i attach it VIA usb and have the cd boot from that? Is there some key command i could use to fix the drive, or see whats wrong? The hard drive (questionmark on boot) was pulled from a wallstreet in unkown condition, could that be botching up othre things? If so, couldnt i take my hard drive from my pismo,and put it in my powerbook g4, and use it without reinstalling the OS? Lots of questions, hope someone has answers! Thanks!
