Re: [LINUX_Newbies] Recover Windows Partition_GRUB does not recognize Windows partition

You can rewrite grub using the Kubuntu Live CD or any other one.

Got to https://help.ubuntu.com/community/Grub2/Installing
see the section: Reinstalling GRUB 2 from a Working System

It is rather simple really. You just open a terminal and copy and paste the
line that looks like: sudo grub-install /dev/sda

It should detect any installed OS and give it a grub entry.
