If you second HD is a slave drive for example. Tell Ubie to take that HD. It
will ask you what drive do you want to take. Have Windows on the master drive
and Ubie on slave. Ubie will make up a boot loader and ask what you want to boot
up first at the int boot after the install. Windows must be installed up first.
Windows does not like to share O/S with any body.
