Duplicated Windows 7 in Grub
 

Hello everyone ! So I just installed Ubuntu 11.10 on a new partition on my main HDD where Windows 7 is installed and when at the OS selection menu I get Ubuntu, memory test and two Windows 7 choices. One is Windows 7 (loader) (on/dev/sda1) and the other is One is Windows 7 (loader) (on/dev/sda2.. What's that means ? It seems to be the samething when I boot each.

Thanks and sorry if my english is bad

Not really sure but, it may be that one (sda2?) is your recovery partition if you have an OEM installation.

sda1 is most likely system reserved(resue) & sda2 is the OS.
Try booting sda2 first.

Thanks for the quick answers
I do have an OEM installation and there is a recovery partition but both sda1 and sda2 boots my windows 7 just fine. Here is an image that shows it http://img717.imageshack.us/img717/9104/grubf.jpg
