There is a very misleading/deceptive error that you might run into when installing various versions of the Windows operating system. It typically happens when you load additional drivers for raid controllers, fiber cards, SCSI controllers, etc. That error is:
Error: "Windows is unable to install to the selected location. Error: 0x80300001."
When you get this error you will most likely get it for every available hard drive. Why? Because the error doesn't actually have anything to do with the disk that you are trying to install the OS too. It is complaining because the OS install CD is no longer in the drive because you took it out to load the drivers!
Resolution: Put the OS install CD back in the CD drive!
