Now that Apple has released OS X 10.9 Mavericks, you might want to consider creating a USB install drive for clean installs and future use.

Step-by-step guide explaining how to make a bootable OS X El Capitan beta USB installer drive.

Given below are the steps, showing how to make a Mountain Lion bootable USB/SD Card/DVD drive using the Lion DiskMaker. Must note that Lion DiskMaker will erase the volume or the drive you chose.

I've even heard of success stories involving making the USB media then burning the partition itself to a double-layer DVD disc - and thus having a bootable optical disc version for your older Macs.

Has anyone tried dragging the “Install OS X Mavericks” App from the bootable USB Flash Drive w/ Recovery Partition, as outlined by TyWebb, back to the Mac’s Applications folder?
