" see if it will boot to safe and select "Last Known Config that worked ""
Partition table is not related to windows' settings, and therefore "last known config" will not help.
When a partition table is damaged, you can not boot at all. Most likely data in that partition is all gone too.
For my case, I've managed to recover the data, but it doesn't boot.
For PowerQuest Partition magic. Hmm......., I don't want to spend any money on it. I am sure there are other freewares for manual partition editing.
Thx both for commenting anyway.
