Click on the Erase icon in Disk Utility's main window. A panel will drop down. Set the Format type to Mac OS Extended (Journaled.) Click on the Apply button, then wait for the Done button to activate and click on it. Quit Disk Utility and return to the Utility Menu. Select Reinstall OS X and click on the Continue button. I know of two ways: 1. Run the OS X 10.11 installer. This works even if you already have OS X 10.11 installed. It will automatically create the recovery partition without affecting your currently installed copy of OS X. OS X El Capitan PWN: Uploading.TransMac: Uploading.
I've been testing El Capitan Beta 6 on a MacBook Air and I found one issue that I hope someone can confirm is a bug, or maybe I'm just doing something wrong.

Starting with a USB bootable El Capitan Beta installer, initialize the SSD target drive, then install El Capitan, then go through the tedious/painful process of having 10+ GBs of updates pulled down (just a guess), until we are at El Capitan Beta 6.
Right off the bat I notice Recoverey HD is missing.
Running diskutil list shows Macintosh HD is there, but not Recovery HD.
Data Recovery Usb
Running diskutil cs list returns No CoreStorage logical volume groups found.
I booted off the USB bootable El Capitan Beta installer and created a DMG using both New image from Macintosh HD and New image from folder... this way I can at least restore Macintosh HD at a later date if necessary (fully updated to Beta 6).
I didn't bother to create an image from the SSD, since it is missing Recovery HD. Ideally I should be able to, to capture both Macintosh HD and Recovery HD.
I'll probably get slapped for asking, but I'd like to avoid going through this exercise a third time...
Is there a way to create a proper Recovery HD in El Capitan Beta 6 where it does not exist?
I'll be in purgatory if anyone responds.
