help needed

[mylo]

I am pulling my hair out trying to do what I think must be one of the most basic tasks in Photoshop. Trying to remove a background.

This is the scenario: I have a circular image with a plain white background. Using the magic wand I select the background and delete it (Select/Inverse, then Delete). The grey/white checked background results.

I save as a TIF file and then load the image into another application.
Please help me......
