Creating a bootable USB for Centos on Mac OS X

Published / by tuxninja / Leave a Comment

I’m a huge Ubuntu fan. However, most of my ‘day job’ work requires CentOS or RHEL, thus I commonly have to re-image my on premise Cloud with the latest and greatest CentOS. My servers are 3 Rackables by SGI, two with more CPU & Memory and one (the controller node) with tons of Disk (12x1TB RAID 10) and then for off-premise I use Digital Ocean who has a fantastic product. Most modern servers do not have a CDROM and neither do my on premise systems. Therefore, I need to place the CentOS image on a USB drive so I can re-image my lab. Here are the steps do that on Mac OS X.

List the current Disks & Partitions

My USB drive is the 2GB drive at the bottom, we need to unmount that

Next we copy the CentOS image onto the unmounted USB disk.

When that’s gets done your Mac will pop up a window asking you to initialize the drive, ignore that. Remove it, and your ready to boot off this USB!
