I am upgrading some Lenovo 131e from Windows 7 to Windows 8 with the recovery discs that came with the machines (the machines shipped with Windows 7 but the recovery disk are Windows 8). Problem is, these machines don't have an internal cd rom so the only way to do this is one-at-a-time with an external cd rom. Problem is, I have 35 machines to do with 1 external drive. So I thought I would put the install files from the two discs onto two jump drives. First one went fine but the second one craps out when it gets to a file called m8s3bus2.swm
what is that file (couldn't find it with a web search), do I need it, and is this even a good idea?
