Mark You should actually hold the option key down for about 10 seconds after you hear the start-up sound. If you don't, you'll probably just be landed in to the configured start disk which must be your Mountain Lion installation.

When the Mac start up sound is heard, I let go of the option key. 3. I have hit the left arrow and my Mac does not start. 4. I have also hit the right arrow key and the Mac does not start up either. 5. If I do nothing from start up, it goes into M L. What am I doing wrong? All I wish to do is play with M L for a while, befor installing it over Lion. <--- Mac Access At Mac Access Dot Net ---> To reply to this post, please address your message to [email protected] You can find an archive of all messages posted to the Mac-Access forum at either the list's own dedicated web archive: <http://mail.tft-bbs.co.uk/pipermail/mac-access/index.html> or at the public Mail Archive: <http://www.mail-archive.com/[email protected]/>.
