^^ Ugg, that's clunky too
So instead do this: (
even less complicated)
You will need HP USB Disk Storage Format Tool - v2.1.8 (be warned many google links for the HP tool are DEAD)
You
can find it
Here!
and
Bootme.zip
1. Run "HP USB Disk Storage Format Tool"
2. Select your Thumb Drive as Device
3. Select FAT as File system
4. Volume name "
Windows 7"

5. Select Quick Format
6. Select Create a DOS startup disk
7. unzip the bootme.zip and point "Using DOS system files located at" to the unzipped folder with files inside
8. Start Format
Ta-Da
Sorted!
PS You wont see any files on the usbstick as they are in the boot sector
(you can also optionally do a second "format" using NTFS- don't worry "all data on drive will be lost" does NOT include the boot sector files.
There you go-My first
How to... for WSF.
