I messed up. I installed mint18 on my external drive but mint18 is not
quite ready for prime time so I figured I would put mint 17.3 on. Well,
durring installation I told it to put grub on the external drive. now I
can't boot unless the external drive is plugged in. I need the port the
external is plugged into because that is the only USB port it will boot
from and I need that port  for the thumb drive. So  my question is how do I
install grub to sda1......

Mint won't boot now! How do I RESTORE WINDOWS SO i CAN DO THIS AGAIN?
