I've installed Ubuntu by USB many times before. It's not working now and I'm not sure why.
I format the USB drive (a Kingston DataTraveler 100 G2, 16 GB) using GParted by wiping it and installing a FAT32 primary partition on it. I change the permissions of the drive filesystem from root to the main user (sudo chown user1: /media/user1/4B8C-3997
). I download Ubuntu (wget http://mirror.switch.ch/ftp/mirror/ubuntu-cdimage/15.10/ubuntu-15.10-desktop-amd64.iso
) and then write the ISO to USB using UNetbootin. Then, when I try to boot from the drive, it simply loops back to asking which drive to boot from.
Do you have any ideas about what might be causing this?
