allright, im using windows 8 pro, there are kon boot for cd and usb, n i open file kon bot for usb, n there a readme text, says :

If you are using windows7:
1) Plug your USB thumb drive in
2) Right click usb_install_RUNASADMIN.bat, pick Run As Administrator
3) Follow the installation procedure.


Otherwise:
1) Plug your USB thumb drive in
2) Double click (run) on the USB_INSTALL.vbs
3) Follow the installation procedure



so, insert my usb , double click on USB install.vbs, n it automaticly make my usb bootable for kon boot, get it?
