Ok, so I have an older iMac g3 that died, would not turn on at all. I found a replacement imac g3, a little upgraded. I moved the dvd and hard drive to the new one that boots up and now it's booting to a flashing question mark. I tried a bootable dvd and when I hold down option it will not show the hard drive or the dvd as somethign to boot from. The software cd says it's for a Imac dv models, is that possibly why it's not showing up properly when I hold down option?
