can't install volumio on udoo x86


i’m new here. i’ve been trying to install volumio x86 version on my udoo x86 without success. already use 2 different microsd cards 8 and 16 gb where 16 gb is a new one. when i verify the image using win32 disk imager there’s an error message. fyi i already use the latest bios version on my udoo.

anyone know what’s wrong here ?
