How to Select a Different Boot Drive from Startup Disk Manager You’ll also notice an option to join a wi-fi network when at the Boot Manager, that can be left alone unless you need to perform an internet restore of Mac OS X.

This option on boot trick works for quite literally any boot volume, whether it’s an external USB drive of any sort, a Thunderbolt hard drive, boot DVD, CD, the Recovery partition, even in dual-boot environments with other versions of OS X, or a Linux or a Windows partition with Boot Camp, if it’s bootable and connected to the Mac it will be visible at this boot manager. In this screen shot example, the right-most orange boot drive is a USB flash disk. Similarly, CD’s and DVD’s are shown with a disc icon. You will find that external drives typically are shown with an orange icon, with their interface printed on the icon itself.


We’ll cover the two easiest ways to do this, during boot with the Mac Boot Manager, and also through System Preferences using the Startup Disk selection tool. There are plenty of reasons for booting from external volumes, whether it’s to troubleshoot problems, repair disks, partition, format everything, update, or even reinstall Mac OS X. Certain situations require a Mac to be booted from an external boot volume, rather than the primary startup disk.
