Start up Help for Fuse

I am trying to install the Fuse.

I had a SanDisk Flash drive in one of the card slots.

I put the Fuse disk in the drive. It did not run.

My computer does not now recognize the CD drive.

When I take out the Flash drive, the name for the CD drive goes away,

When I put the flash drive back in BOTH the CD drive and card slot appearl

Somehow the Flash drive has taken over the CD drive.

What do I do?

So I said it wrong. The Flash drive was in and out of the usb port. I am tired.

I sort of need the cd drive to restore the system, if I need to.
