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.
