I don't know why this happened. Eight months ago my logic board was replaced. After that I inherited old backups to new logic board.
If you got the "inherit" prompt, and selected it, that wasn't the problem.
Few months ago, I reinstall Lion due to some other problem. May be that was the cause.
Depending on how you did that, and how you put your data back, yes, that might have been the cause.
My question is: If I format my hard disk and clean install Lion on it. And format my Time Capsule. Start everything all over again. Will the problem be solved permanently without your workaround ?
Yes, but that will erase all your backups. 😟
If I will clean install Lion, how can I get my old stuff from Time Machine backups ?
Why do you want to do that? It won't help this problem, but if you have other, serious, problems, it might be a last resort.
How can I access to Setup Assistant that you mentioned before ? Will Setup Assistant also import Bookmarks and Mail contents to my fresh Lion disk ?
If you erase your internal HD and install OSX on it, when your Mac restarts, Setup Assistant will run automatically, giving you the option to transfer some, all, or none of your stuff. See Using Setup Assistant on Lion.
But again, I don't know why you'd want to do that.
If your only problem is the old backups being grayed-out, here's a possible fix: First, determine the approximate date/time where the grayed-out backups start. Then use the procedure in #B6 of Time Machine - Troubleshooting to make Time Machine "associate" your "new" (current) disk with the old backups. When you drag the volume name from a backup (per the pink box there), be sure to drag one from the time period where the backups are grayed-out (ie, in a folder whose name represents a date during that period).
Note that even though the names are the same, Time Machine thinks they're different -- that's why you need to use one of the older backups.
