Does not Boot

[Peeker]

ok heres the problem I have used wintousb to install windows 7 64 bit on a PNY 128gb USB 3.0 flash drive. the program does the install fine, very slowly but fine. I have tried using both an ISO and my install disc the problems is the drive wont boot every time I try I get the "Disk read error Press cntl-alt-del" I have formatted the drive to be bootable but every time I use the program it insists on reformatting the drive again and I think its wiping out the boot sector so my basic question is what the heck is going on here? and how do I fix this problem? I just bought this drive specifically for this purpose so I don't want to waste $50.00 so could someone please tell me what I'm doing wrong here.....
