Copy all the files that is inside the usbXXXXXX.zip or on the CD onto an usb drive, directly on the drive, not inside any directory/folder.
It is OK if there are other files on the USB drive from before, they will not be removed.
Install bootloader on the USB drive, from command prompt in windows (start the command line with "run as administrator" if possible)
X:syslinux.exe -ma X:
Replace X: with the drive letter the USB drive shows up as (DO NOT USE C:)
If it seems like nothing happened, it is usually done.
However, a file named ldlinux.sys may appear on the USB drive, that is normal.
It should now in theory be bootable.
Please know that getting some computers to boot from USB is worse than from CD, you may have to change settings, or some will not simply work at all.
