I recently bought NG15. My son's computer's hard drive became stuck in a boot loop. I ended up wiping the drive. I have another computer that is an exactly the same with the same OS system. I used NG15 to copy his drive. I was able to sucessfully copy the drive and I can see the data, but when I try to boot using the usb it fails to boot and the drive disappears. I should be able to boot using the USB. I change the BIOs to boot to the USB first. It fails. What can I do to boot to this drive. Should I reinstall the drive and then try booting...the issue is the drive is from an acer one computer..which requires the computer be totally reassembled...help! How do I make a boot disk??
