When I'm booting up, right after the set-up screen it stops with the cursor blinking in upper left corner with thumbdrive inserted. If I wait & plug it in after "Grub Loading" It boots great & drive is recognized.
If I boot into windows everything is OK. Well the windows part isn't. If I try to boot from windows into Linux it won't boot either.
It never has booted with drive inserted in any of the installs I've had to make .
