[Trisquel-users] I can't boot Trisquel 7

[jkir]

I can't boot Trisquel 7. I try to use dd if=trisquel.iso and I try to use  
Unetbootin to make bootable usb drive. After booting from usb, I see main  
screen, I take try trisquel without installing or install trisquel, and the  
same: black screen with blinking ampersand. And LED on usb drive is not  
blinking. Please help me, I'm going to use Trisquel 7.
