How Do I Switch Startup Disks In OS X Lion?


How do I select the startup disk after restarting my computer?
- Asked by Virginia S. January 6th, 2012


There are a couple ways to select your startup disk. If you have just restarted, immediately hold down the Option key and you will be prompted with the option to choose your startup disk. You can also choose your startup disk before restarting. Just go to System Preferences -> Startup Disk. Select the system that you want to use and hit Restart.
