windows-7

It fails and it says 'cannot find device'. It will work again if I reinstall Windows, and use something like EasyBCD. But I'd like grub as a loader only, can someone help me out here? My system has a regular BIOS (p35-ds4 mainboard) so no UEFI support.

Previously ran Windows 8 alongside ubuntu 13.04, now wanted windows 7 again with ubuntu 13.10.

I am using disk /dev/sda.
