They work great! Especially since the Microsoft Tool was pulled and didn’t work for me anyways.
An other way to create a bootable USB drive to install W7 from is:
Format the drive from a Vista/W7 machine:
FORMAT F: /FS:NTFS (where F: is of course your USB drive)
Activate the first partition on that drive:
SELECT DISK x (where x is the drivenumber shown from the previous command)
SELECT PARTITION 1
Mount your newly downloaded ISO from Microsoft with Daemon tools or other mount-tool
Place a W7 bootsector on the drive:
Z: (where Z: is your cdrom drive where the ISO is mounted)
BOOTSECT /NT60 F:
Now copy all of the files of the mounted cdrom to the USB drive
XCOPY Z:\ F:\ /S/E
Now boot from the USB drive to install W7!
