Greetings, I have an issue to where I can no longer boot into the Mac OSX partition after what appears to be a failed Windows bootcamp install. As I was running the bootcamp assistant process, a reboot occurred and I was greeted with the "No bootable device -- insert boot disk and press any key". I have no idea how to get past this and boot back to OSX. Things I have tried: Holding down the "option" key does nothing, even using a USB keyboard Resetting PRAM (CMD + OPT + P + R) does nothing, even with USB keyboard Cannot boot to a USB drive that I have put WinPE on I also pulled the hard drive out and connected it to another PC and wiped the drive completely. I put it back in the macbook and I am still presented with this error. It seems, even though I get the Mac startup tone, that it is stuck in which ever OS it tried to run previously, that being Windows. Not sure why I am still receiving this error even after wiping the drive completely clean. As far as hardware goes, I am pretty sure its a late 2010 Alumn. Macbook Pro. I cant get the current model number since I cant boot the OS. Any help is appreciated.
