Hey there,

I have an .iso file of Windows 7. What do I need in order to install it via Boot Camp? Must I have a flash drive?( I don't have DVD on the rMBP). I have usb external hard drive - is it ok to use it instead of flash stick?

Thank you!
 
Yeah you can use the hard drive. Be careful though because it'll be erased when boot camp copies the ISO over.

I was afraid it would erase it... Thanks for the letting me know. Is it possible to install using only the .iso file without DVD or external flash/hard usb drive?

Thanks.
