Thank you for using slax!
If you are reading this from a CD, it is already bootable.
Steps to make it bootable from your USB device are following:

1) Copy the entire /slax/ directory to your USB drive.
   If you are using Windows, you will get for example E:\slax\
   You probably already did this - just make sure you are on your
   USB drive now and not on your local harddisk.

2) Now navigate to directory /slax/boot/ on your USB drive.
   In Windows, it will be E:\slax\boot\ for example.
   Use explorer or any other file manager for this task.

3) While you're in the boot directory, locate file bootinst.bat
   Run it by doubleclicking it. It will setup your USB to boot.

-- That's it. Your USB device is now ready to boot slax.
-- You can safely delete this file (readme.txt), it's not needed.

1.The instruction is to Copy the entire /slax/ directory to USB drive.
2.Then navigate to /slax/boot/ on the USB drive.
3.Then run  bootinst.bat
4.It will setup the USB to boot.
The USB device is now ready to boot slax.
