Thank you both for your input.
I think I may not have explained it well. The computer current tries to boot from USB first. I wanted to get a system that booted to windows unless I had the Linux USB drive plug in. When I ran the install I did not find any option not to installed grub Ubuntu just went ahead and did it, which would have been ok if it had worked. Now thanks to Mandriva, Grub is gone. If it was a version of windows on the USB drive my first try to fix it would be to run Fdisk and make the first partition to bootable does Linux have a similar system. I will fix grub if I canít get this option to work.
