Long story short: I upgraded to Leopard but before doing so, cloned my Tiger disk using CCC (Carbon Copy Cloner). In a desperate attempt to get OS X Migration Assistant to recognize my bootable Tiger, I used Disk Utility to find out the drive holding the Tiger clone had errors and after much trouble, eventually repaired it. The only thing I noticed that was different before and after the repair was this: Before the repair, I could restart my Mac, hold down option, and boot straight into Tiger just like the day I left it. It had my login icon and when I clicked it, it only asked for a password. Now, attempting to boot into Tiger gives me no screen with my user picture, and strangely enough, it asks for my password AND User name. I've tried every user name I can think of that SHOULD work and the password that I know definitively and Tiger is not letting me in ....I've included a picture taken from my phone of the log in screen (Notice the strange overhang from what looks to be another window below it. I've clicked to no avail). This is so weird. Because in Leopard, if I connect the drive housing the Tiger clone, I can peruse thru my Tiger disk all I want and grab whatever I wish. But what I need to do can only be done by booting straight into Tiger...Which it's not letting me. Any advice as to why Tiger is being such a pain in the ass now?
