EasyRE doesn't work. At least not for me.

My bootmgr is missing. Bought and downloaded EasyRE, created a bootable usb flash drive (in FAT32) using the Easy USB Creator. I never even get the "automated Repair" screen I see in the demo video, just a GNU Grub screen that I know nothing about. There are 3 choices. 1 is Easy Recovery Essentials, 2 is VGA mode, and 3 is Safe mode. Tried all 3...nothing. Bunch of writing with the words "failed" coming up in about every other sentence. Then the sentences "Timed out trying to locate boot files" and "Unable to locate boot files". Am I doing something wrong? Thanks
