Ask away: http://ask.fedoraproject.org > Sorry Kevin, top post is a standard behavior of gmail :( so sorry for that. on that computer i have 6 HDD...all others are windows formatted HDD but none has a boot... but in former windows 7 my actual SDB was as first HDD in disk manager, so with ID=0.. now it has ID=1 (so as 2nd HDD), but still not bootable. in fact none should have a boot manager as my REAL former C:\ drive has crashed and therefore i replace it with the one i have now as SDA :) I hope it is clearer :-/
