Sorry Klaus,

I updated this post about 8 hours ago - clearly it didn't take (grrrr), here's what should have uploaded...

Fix for missing Windows link in Grub2 menu:

The steps for this require root access, so use Root Shell or sudo.

Edit file:
/etc/grub.d/40_custom
Add this section to the end of the file:
menuentry "Windows 7" {
set root=(hd0,1)
chainloader +1
}
(Note this worked for me as Windows boots from first partition (sda0,0) - partition numbering changes in Grub2, now starts at 1 not 0)

At command prompt run:
update-grub
That's it, this curred my missing Windows option in grub2 menu.
Missing wireless is proving harder to track down, and is still causing a problem if anyone can help?
