I woke up today and tried to boot my mac, but it wouldn't boot, so I went into disk utility and did a repair disk (it tried to repair catalogue b) but it couldn't. So, I decided to do a Time Machine restore as it was only a day old, and I won't lose a lot, if any, of my stuff. The restore is at 7.5% with 4 hours to go until it finishes. However, when I looked at the log all it says, for about 2000 lines is this repeatedly: OSinstaller bookmark failed to issue extension for item /com.apple.recovery.boot/basesystem.dmg (depth=4001) no such file or directory. OSinstaller bookmark failed to issue extension for item (depth=4000) I'm guessing this isn't normal. There are only a few lines at the top which say that it's basically starting the backup. I can only here a few movements in my external hard drive; otherwise it doesn't seem to be doing anything. Im on lion, and using the recovery partition. I also did erase one of the two partitions on my hard drive, before going into restore my computer by time machine.
