I made the iso on xp with no issue from Rufus, I selected:From the Rufus page I read that USB bootable media that was made on Windows XP does not work with UEFI/GPT.
Only UEFI/MBR is supported.
Ok, I will have a rethink over the next few days, I've sent an email to Asus support, but expect just a generic response. I may be able to redo the USB on my sister's Windows 7 laptop, but still cant see how my laptop will boot from the usb outside of windows now.You can try it, but I am afraid that you have GPT partition on the new laptop, so it may not help. The UEFI/GPT option in Rufus is available only on Windows Vista+.
