Q: Still having issues with installing Yosemite after deleting "Backups.backupdb" on the internal hard drive.  I have restarted multiple times and cannot find any other back up files, yet I still receive the same error message during installation.

I am using a 2011 iMac on 10.6.8. I recently downloaded the Yosemite upgrade and during the installation process ran into the "this disk is used for time machine backups". I ejected the external drive I use for time machine backups and turned off time machine in the application. I then followed the instructions of the help article (OS X: Cannot install on a volume used by Time Machine for backups - Apple Support) by moving the folder "Backups.backupdb" that I was able to find on my internal hard drive to the trash. I have restarted several times after completing this process. I am still running into the same error during the installation process. I have searched the hard drive for any other backups and I cannot find any. I searched the hard drive using the command cmd-shift-g and searched for “backups.backupdb” and was unable to find any folders or files. Any other suggestions?

iMac, Mac OS X (10.6.8)
