About 5 days ago, I installed a program that required a restart. I restarted and then my computer started boot looping. I preceded to use the disk-part method and wiped my C: drive. I then had a new error missing operating system. I decided to use the Chromebook recovery utility to burn my ISO to the USB. It said burn was successful. I then plugged in my USB with the windows 7 and it said no boot-sector found on the USB. I am really frustrated with my predicament and I am out of solutions. I have a dell latitude E6400. PS. It worked fine for about 7 months.
