please someone help me....

(Sorry for my english)

Hi, I have a Pc with 2 Hd (1Tb each) on Raid0. I had a Windows 7 64bits working for several months. When I installed the Windows I let a 100Gb partition empty to install Ubuntu someday. I was using Linux on a Virtualbox, but this week I tried to install Ubuntu 12.04 in this 100Gb partition.

I used the Ubuntu alternate cd, because the 'normal' cd was giving me trouble with the Raid0. The grub installation always reported a error. After a lot of work I found that I nedded to install grub on partition /dev/mapper/isw_chjbfeec_DougRaid1 (see Bootinfo below).

The Windows installation created a 100Mb boot partition, so I needed to install grub in this partition.

Now I have the Ubuntu working 100% ok.

The problem is, the Windows is not booting! The windows option is present on the grub menu, but when I choose the windows option there is a black screen and after that the grub is reloaded.

My Bootinfo is:

How we can see the Windows part at grub is:

menuentry "Windows 7 (loader) (on /dev/mapper/isw_chjbfeec_DougRaid1)" --class windows --class os {
        insmod part_msdos
        insmod ntfs
        set root='(sda,msdos1)'
        search --no-floppy --fs-uuid --set=root C89C73D19C73B910
        chainloader +1
    }

I tried a lot of combinations at the line:

set root='(sda,msdos1)'

, but no success

I tried to change uuid to the /dev/mapper/isw_chjbfeec_DougRaid2 uuid, but the grub reports a error.

I dont know what to do now.

I really need to boot my windows partition.

Someone knows what to do?

Thanks........
