Hmm... It's tough to discern this strange English-type language you seem to be speaking, but I think you need to boot from a CDROM or floppy disk...
This is configured in your computer's BIOS. When you boot the system, you need to press a key to enter the setup (it will probably be displayed on the screen somewhere like this:)

Press <INSERT_KEY_HERE> to enter setup.

Press that key as the computer boots and change your computers "Boot Order" (may be worded differently) to boot from said device.
