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 :-/
