Q: El Capitan says it cannot install on my hard drive. Have 2009 iMac with 187gb available on drive.  What do I do ?

I have 2009 iMac with 320 gb hard drive, 8 gb ram, running OS 10.10.5

Downloaded El Capitan.  However it says it cannot install on my hard drive. 

The 2009 iMac is supposed to be able to run the new OS - how can it run it if it can't install it?

How do I resolve this??

Thanks - kathy

iMac, OS X Yosemite (10.10.3)

    Repair the Hard Drive and Permissions - Yosemite, Mavericks, Mountain Lion or Lion

     

    Boot to the Recovery HD:

     

    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears.

     

    Repair

     

    When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the indented Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu. Select Restart from the Apple menu.


    Now, try re-downloading or reinstalling El Capitan.
