Laptop running 13.2 has boot installed on root on /dev/sda2 and windoze 7 installed on /dev/sda1 and dual booting used to work.
Following extensive efforts to repair windoze I ended up re formatting /dev/sda1 with NTFS and doing a new installation of windoze.
At some point in this process the windoze menu item on the grub boot screen disappeared so i now have either a working 13.2 or a working (if you can call it that,) windoze 7 but to boot I have to change the boot flag with live gparted to whichever system I want to run. How can I restore the menu item for windoze so that dual works again please?
