Cannot load Windows 7 after installing SUSE Enterprise Svr

Good day,

I am in a real fix here. I downloaded SUSE v11 SP3 and attempted to install it on an external USB drive using a Windows 7 PC as the hardware platform. The installation went off without a hitch. SUSE runs fine off the external USB Drive. The problem is now Windows 7 will not boot. I am getting a Grub2 error 21. I tried booting from the Windows 7 installation disk and performing a start-up repair, but it didn’t work. This is a production PC and I really need it back up and working. At this point the only solution I can see is to reformat the hard drive and perform an entire Windows 7 installation, which will take the PC out of production for at least a day with downloading all of the security updates, drivers, etc.

Is there an easy way to fix this?

Hi
With the system booted into SLES, can you post the output of;

fdisk -l
cat /boot/grub/menu.lst
