[QUOTE="schlagi, post: 1618423, member: 336474"] To boot from the stick, switch off your Mac, stick the USB drive in, press power and option keys (left one), wait at least until you hear the gong sound. You should be presented with a choice of available boot drives, including the USB drive. Select this and start from it. See if you can just select your hard drive as install target (this may only replace the bungled system, without data loss); if this does not work, you will need to format the disk. THIS ENTAILS IRREMEDIABLE DATA LOSS OF ALL THAT WAS ON THAT DRIVE! Then install on the freshly formatted drive. You will now have a virgin Mac. More in a third post [/QUOTE]
