I have created a usb flash drive in Ubuntu 16.04 using Startup disk creator, unetbootin, dd and the restore disk image in Disks. I have used the ubuntu 17.04 image and the Kubuntu 17.04 image. The MD5 hashes are correct. And my PC just sits there and nothing happens. With different usb sticks.
If I use the Lubuntu 17.04 image then everything works normally. Same usb stick.
I have tried on a second PC - also does not even reach the POST.
How is this a duplicate question? I can make a bootable USB but it will not boot if I use a 64 bit image even though the PC currently uses 64bit Ubuntu?
All I want to do is install Ubuntu 17.04
