Installing FreeBsd. No usb device found

Hello, all. My english is not good.
I have a problem installing FreeBsd.
I have not CD-Roms, so i use program FlashBoot for convert iso-image to USB Device.
After, I was beginning to install FreeBsd (Sorry my english)
When it's time to choose an installation media, i select 9 USB:

however a message tells me:

No USB Devices Found

My next step was to Re-scan devices:

I use space bar to select this option, but nothing happened.
After that I try again to choose the installation media:

No USB Devices Found

Help me.

Hm maybe your usb pendrive is not recognized i.e not supported. Can you try with other pendrive? You can also use UNetbootin - Homepage and Downloads it has option to convert FreeBSD iso to bootlable pendrive.

I did as you said, but nothing worked.
Tommorow I will buy new notebook xD.

It may not see it as USB media. There's no telling how their CD-to-usb converter works, there really is no direct conversion, it means alterations to settings inside the software that must boot.
