Hello I have a macbook which is all messed up and currently has no operating system whatsoever. I got a Leopard.dmg installation file, but I do not have a dual layer DVD, so I decided to install it from my external USB Hard drive. I formatted it to HFS+ (the OSX file system) and extracted the .dmg onto that partition. When I start the Macbook with the drive plugged in and while holding the option button, it shows the external drive as "EFI Boot" and after I select it it asks to restart the computer. So, my question is: How can I make a bootable image of leopard on my external HDD, while I'm on windows? *Edit* I tried to run the EFI Boot thing, and i got yet another error: Unable to find driver for this platform: \"ACPI" ... Thank you very much.
