    Well, this was unexpected.

    Computer: 2010 iMac with 256GB SSD + 2TB HD + external Time Machine drive

    Only the 2TB HD is selectable for installation as the other two drives are greyed out with the message "This disk is used for Time Machine backups".


    So I turned off Time Machine,disconnected drive, and restarted computer. I still get the message about Time Machine.



    Any suggestions? Thanks!

    I had the same issue. Open your HD folder and look for a backup folder there. Either delete it or move it to another drive.
    I think the folder was put there when I transferred my settings from my MacBook Pro to my new iMac.

    Specifically, what is the backup file called and where is located? Thanks!

    The folder is pretty obviously named: `Backups.backupdb`

    Just ran into this issue, and renaming the folder did indeed fix my problems... figured this might help someone!
