Cant boot from USB

[byubi]

Hi, I have a new PC with 'asrock h81m-vg4', I'm trying to boot from USB to install windows, but it's not working.

When I enter the UEFI > Boot > Boot Option # 1 , I get these options:

 

- AHCI PO wd10ezzx-60m2na0

- USB: generic flash disk 8.07

- UEFI: generic flash disk 8.07

- disabled

 

I tried the 'USB: generic flash disk' and 'UEFI: generic flash disk' and both didnt work.

Solved: the problem was the usb drive, if you have a 32-bit system and a 64-bit iso, 'Windows USB Download Tool' will copy the files but it won't make it bootable. There is a workaround though.
