I have had problems after latest update - parallels, airport loss etc. so I thought about restoring my mac with time machine, but after inserting leopard dvd, I only get the initial leopard "galaxy" screen, nothing else. Tried holding c key, via disk utility, etc. Cant boot up in safe mode nor single mode. Wondering wether it is because I am only using an external screen - the screen of my macbookpro went a long time ago. Any ideas?Thanks.
