Due to internal Superdrive death, I bought an External DVD Drive, its LG DVD 5163D Firewire and USB, connected thru FW to my iMac 17 CoreDuo Early 2006 with Leopard 10.5.5 I did the BootCamp partition below 32 GB, clic on Continue, system boot and a black NON BOOTABLE DEVICE, PRESS A KEY TO... screen shows. No matter what, it keeps showing this. I guess it could be my XPSP2 copy, but I did installed from same disc on this machine using Tiger and the internal Superdrive, back when it still works. I even did a FreeDOS system (someone says this could be the problem, XP won´t format the BOOTCAMP partition), black screen again, what drives me to start thinking that the problem is not with discs but the DVD Drive instead. I guess Leopard doesn´t likes my Drive. Worth to say, Leopard installed flawless from this Drive, and if trying to boot Leopard from CD works ok. Is there any way to force Leopard to boot from external DVD? (assuming this is the problem) Is there any know issues with 10.5 and booting from external DVD? Anyone goes thru this? I couln´t find any case like this. Please Help!
