Possible Repost (Sorry) Windows 7 vs Ubuntu

[Carlton Brooks]

I have 3 HARD DRIVES. Drive 1 (sda) is a Windows 7 Drive. Drive 2 (sdb)
is a data drive. Drive 3 (sdc) is an Ubuntu 11.04 drive.

I just upgraded to 11.04 by disconnecting sda and sdb. I then installed
11.04. I then reconnect all the drives

After install I did a sudo update-grub. It displayed the following

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.38-8-generic
Found initrd image: /boot/initrd.img-2.6.38-8-generic
Found memtest86+ image: /boot/memtest86+.bin
Found Windows 7 (loader) on /dev/sda1
Found Windows 7 (loader) on /dev/sdb1
done

I have no idea why 2 Windows.

Then ran fdisk -l. It displayed the following

Now when I boot up it shows the grub menu, and lists all the choices,
but when the Windows sda1 is picked it reboots. When sdb1 is picked it
says I have a windows error.

I beleive I have corrupted or destroyed the Windows MBR or Boot Record.
I have attempted to fix it using the Windows disk but still does not
work.

Any help would be appreciated.
