It should be available (at no additional charge) on your App Store --> Purchases page.Painful, but hopefully the pain is worthwhile to get a flawless system.

OS X can't be installed on the disk an error occurred while installing os x mountain lion Macintosh HD because a recovery system can't be created. Visit www.apple.com/support/no-recovery to learn more." The installer log shows the message, "Recovery system creation failed with error -69713 (The booter/recovery partition must be grown by https://discussions.apple.com/thread/4164347?start=0&tstart=0 a larger amount)." You may be presented with an option to select which disk is the target for installation. In some situations, the disk you want to upgrade may be labelled "This disk cannot be used to start up your computer." If possible, back up and reformat the target disk before installing. If you aren't able to back up and reformat, try the following steps to resize the partition where https://support.apple.com/en-us/HT203482 you want to install OS X: Restart your Mac from your usual startup disk. Open Disk Utility, located in /Applications/Utilities/ . Select the disk where the volume you intend to upgrade resides. This usually starts with a number representing the total size of the disk. Click the Partition tab. Click and drag the resize corner of your intended install partition to make the size slightly smaller. The blue portion represents used data space. The partition only needs to be approximately 128MB smaller than it was before resizing but it needs to be larger than the blue portion. Example Before: After: Click Apply. When the partition resizing is complete, quit Disk Utility and install OSX. After the OS X installation is complete, you can use Disk Utility to resize the partition back to its original size by dragging the resize corner to make the partition as large as it was before.

Tech Tip: ‘An Error Occurred While Preparing the Installation’ Fix Monday, July 6th, 2015 | Author: OWC Robert J. Having worked in Technical Support here at OWC for some time now, I have helped customers handle many different types of errors and problems that they have come across. Some such as, “The disk you inserted is not readable by this computer,” might have simple solutions like formatting an error the disk, and some are more difficult such as “My Mac keeps freezing. Help!”One error that customers often come across while upgrading their machines occurs during the re-installation of OS X, and it has a relatively simple fix.Once booted into the recovery partition and selecting “Reinstall OS X”, the “Eligibility Verification” window shows up. The error occurs as soon as you click “continue”. An unspecified error shows up which states "An Error occurred while preparing an error occurred the installation. Try running this application again." Upon doing so, the same exact error pops up. Nothing has been done to have this occur, so what exactly is going on?While this can be frustrating, something quite simple is going on in the background that needs to be addressed. One of the checks that occur during “Eligibility Verification” is to see what time the machine thinks it is. If the computer is reporting the wrong time, an error will occur.While there is a simple fix, it does require using the Terminal to accomplish. Many users might be wary of the Terminal, feeling like something could break and that it’s something only hackers and System Administrators use. While this can be true, the Terminal can be your friend and help you to resolve quite a long list of issues that commonly occur. But with great power comes great responsibility. Terminal can be destructive if its abilities are improperly used. My recommendation for those that are wary of this wonderful tool is to copy/paste commands or to type them very carefully and to double check what was typed before execution.To fix the aforementioned “unspecified error”, follow the steps below:First click “OK” on the error window.Then click on “Utilities”, then “Terminal”.Once opened type in “date” without the quotes and hit enter. This will give you the computer’s current time and date.
