Change the Mac Startup Drive on Boot
Mar 22, 2011 - 4 Comments
A Macs startup drive can be changed during system boot by holding down the OPTION key, this will bring up the boot drive manager. Selecting a boot drive from this menu will not change your default drive, this is a one-time only choice of which drive to start from.
I use this to change my boot OS from Mac OS X 10.6 to 10.7, but I set my default startup drive to 10.6 for stability reasons. You can read how I setup a dual boot Lion & Snow Leopard installation for more on this.
I didn’t know the MacBook Air had a Recovery HD partition, I thought you only needed the USB key?
Yes the new MacBookAir have an USB Key verry nice. But I dont see recovery Disk, I know this will include with Lion.
PS: atl at boot is not a Tips and Tricks but a feature… :/
You can also set the startup drive in System Preferences > Startup Disk
You can switch it around any time but what you leave it set on becomes the default boot disk.
lol what a tips :p
