Hi Ken,
If you are sure your Mac & you, are prepared to upgrade to Mountain Lion.
If when you run the Installer you receive the same message as before:
Can't install Mountain Lion on HD - "This disk is used for Time Machine backups"
This message means that the Lion or Mountain Lion installation will not
successfully complete.
The message can appear even though your startup drive is obviously not acting
as a Time Machine backup.
The likely cause is an errant Time Machine-related "Backups.backupdb" folder at
the root level of your drive.
This folder, created by and used by Time Machine, is fooling the Install app
into thinking your startup drive is actually a Time Machine backup.
The solution is to 'Delete the Folder.
If you double-click on your hard drive icon the Backups.backupd folder should
be on the root level of your drive.
Sometimes OS X gets confused and incorrectly puts a Backups.backupd folder on
your hard drive.
That folder should only appear on a drive used for Time Machine.
To Delete the 'Backups.backupsdb" folder
1. Start up from the disk you want to install on (Your Mac).
2. Move the "Backups.backupdb" folder from the root level of your hard drive to
the Trash.
Enter your Administrator Password if prompted.
IMPORTANT: Do not empty the Trash unless you have a backup on a different disk
and want to delete the Time Machine backups from this disk.
3. Empty the Trash
4. Reboot your Mac
5. Install.
If you can't find a "Backups.backupd" folder anywhere try booting into "Safe
Mode" by holding down the "Shift key" right after you hear the startup chime.
Keep holding the Shift key down until you see the Apple Logo.
The progress bar that appears indicates the progress of the file check that
Safe Mode automatically does.
Give it time to finish.
Reboot normally and see if the ML installer will work. If it does wait until
Spotlight is finishing indexing before turning Time Machine back on.
Cheers,
Ronni
