Answer 1

It can't be tell this way.

You have to go through boot option during boot press F9

See if you can see the option to boot up from your flashdrive.

If it is bootable then you can install Windows 7 too.

If it's not bootable then you have made some mistake during formation

of bootable Flashdrive.
