Many times you may have seen that you need to boot, to a volume other than the main OS X installation on your mac, either through a specific software configuration without affecting the main workflow or to troubleshoot an existing OS X installation by loading a new one from an external fresh.
ways to Boot From Another Drive On Mac:
There are plenty of reasons for booting whether it’s to troubleshoot problems, partition, repair disks, update, format everything, or even reinstall OS X. Here in this tutorial we are going to discuss about the two easiest ways to do this:
- Mac Boot Manager
- Second one is through System Preferences using the Startup Disk selection tool.
Mac version Lion (10.7) or newer than this will be able to use the Boot manager to startup from the Recovery partition.
Booting from an External Device with Boot Manager
This can be done to select any bootable drive connected to the Mac:
- Connect the respective external drive to the Mac.
- Reboot the Mac and after the startup press the OPTION key during boot until you get the boot selection menu
- Click the external volume to boot from it.
External drives are shown with an orange icon, with the interface printed on it. Similarly CD’s and DVD’s are shown with a disc icon.
This option on boot tricks works quiet literally for any boot volume, whether it’s any kind of external USB drive, a Thunderbolt hard drive, boot DVD, CD, the Recovery partition; if it is a bootable and get connected to the Mac then it will appear on this boot manager.
Selecting a Different Boot Drive from Startup Disk Manager
You have also an option to select a different boot volume from the Startup Disk system preference section:
- Just attach the boot drive to the mac.
- From the apple menu, open System Preferences and select “Startup Disk” option.
- From the given list select the newly connected boot volume after then choose the “Restart” to start from that disk.
One thing that you need to consider about this approach is that the option of setting stays in the same place until it has been changed again through the Startup Disk Manager. This means that if the selected startup has been disconnected somehow from the Mac then on the next reboot a blinking question mark may appear on your screen because the set startup disk is no longer visible. If the question mark still appear then to fix this out just hold down the OPTION key, selecting the normal Macintosh HD boot volume as startup as described above and then going back to startup Disk in System Preferences to select the right OS X startup volume again.
If while doing all these, if any how your Mac file data gets corrupted or lost up then to fix this issue you need to use Mac data recovery tool.
