[QUOTE="chscag, post: 1450914, member: 46727"] Hook up a wired keyboard, reboot the iMac and hold down the command + r keys as soon as you hear the bong sound. That should get you into the recovery partition. From there you can choose to reinstall Lion. Reinstalling Lion will not wipe out your docs or data. After reinstalling, be sure to update Lion to the latest. And from now on, use Time Machine to make backups before doing any updates. And buy an UPS for your iMac. :) [/QUOTE]
