I've been trying to boot a Windows 7 (yup) USB in this laptop, but neither using UEFI nor Legacy boot would work. In UEFI, always boot the HD even if it's last in priority list. In Legacy boot, nothing works.
My USB is partitioned as a boot CD (yes, that's a real booting device, if you doubt it), but that laptop doesn't say so.
What should I do next? Is there any way for booting from USB or should the HDD be changed?

I do not know if you have finally installed Windows 7, but I had the same issue and I resolved it this way:
or
After you rebooted at step 3, you can press F12 and select from there your boot option (USB).
It worked for me, I found out that the problem was the USB 3 port. Maybe if I put it in the USB 2 ports I wouldn't need all these steps.
