Windows is unable to install to the selected location. Error 0x80300001

After installing drivers during a Windows-installation you might get this error message when you select a drive to install it on “windows is unable to install to the selected location. Error 0x80300001”

This is another (strange) way for Windows to say that you have not inserted the Windows CD/DVD again. Put it back in again, wait a second and then the error message should disappear. (If it does not, try to hit refresh after putting the CD in)
