How to make a bootable OS X 10.10 Yosemite install drive<article>

Back in the day when we bought OS X on discs, as long as you kept that disc, you always had a bootable installer just in case. Modern, downloadable versions of OS X create a
recovery partition on your drive, but it's always a smart idea to make your own bootable installer drive too.</p><p>
I recommend making one for Yosemite, on an external hard drive or USB thumb drive, for many of the same reasons I recommend
making a bootable Mavericks installer drive: If you want to install Yosemite on multiple Macs, using a bootable installer drive can be more convenient than downloading or copying the entire installer to each computer. If you want to erase the drive on a Mac before installing Yosemite, or start over at any time, you can use a dedicated installer drive to boot that Mac, erase its drive, and then install the OS clean and restore whatever data you need from a backup. And if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk.</p><p class="jumpTag"><a href="/article/2367748/how-to-make-a-bootable-os-x-10-10-yosemite-install-drive.html#jump">To read this article in full or to leave a comment, please click here[/url]</p></section></article>
