grub2

I had installed on my computer as a dual-boot: Debian Squeeze and Windows XP, so I decided to install Windows 8 just to test and then I would remove it and install in its place Debian Wheezy as dual-boot with Windows XP, that was already installed.

During the Debian Wheezy installation, I deleted the Windows 8 partition to install Debian W. on its place. The problem is, that after the installation finished I rebooted the computer and on the grub menu was written: Debian Wheezy and Windows 8 (loader) - this Windows 8 (loader) is a boot manager as grub, and after the Win8 installation I was capable of choose between Win8 and WinXP. And when I select Windows 8 (loader) it says the Windows 8 is corrupted and is not possible to boot Windows XP. So, after that, I would like to know, how can I get Windows XP on the grub menu? Because I know its there (the Windows XP), but I can not boot it from grub.

Observation: I already tried update-grub, but it only finds Debian W. and Windows 8.
