A "J" in top left of the screen (or a flashing cursor) is usually a problem with the bootsector. (more specifically it is often connecte with unbalanced CHS/LBA and or with geometry of the filesystem)

HOW (meaning BOTH):

1. WHICH tool
   
2. HOW EXACTLY did you use it
   

was the USB thingy partitioned/formatted?

More generally describe in better detail, WHAT (which device) are you attempting booting from USB, it's size, the filesystem used on it and under which OS did you prepare it.

Well WIN TO FLUSH is probably WINTOFLASH.

But athough I don't see why you haven't asked for help on their Forum , the issue is most probably (please read as definitely) in the way you formatted the USB stick.

Use RMPREPUSB (and nothing else) to partition and format the USB stick:

Preferrably (but of course not at all mandatory ) use our own app to create the Windows 7 base for install:

(BTW it already includes RMPREPUSB)
