boot - How to reinstall Ubuntu 16.04 LTS - Ask Ubuntu


i have installed ubuntu 16.04 lts cannot beyond login screen. have tried 3 recommended fixes relating nvidia without change , hope reinstall o/s others said might help.

i have downloaded ubuntu-16.04.1-desktop-amd64.iso ubuntu download site onto wife's apple our working machine now.

i have copied sandisk drive , tried use reinstall ubuntu on preferred machine. have set usb drive preferred boot drive computer reluctant install "no mountable file systems"

i not want go windows after 6 years of sequential ubuntu o/s's seems login defect on 16.04.1 cannot overcome. cry out there has solved login problem. thanks

i hope when put on usb, don't mean iso file :)

if did, no harm done.

an iso file disk image, , put on usb, have write contents of iso on usb, not iso itself.

process

so can command prompt on mac this:

$ diskutil list

find usb drive in list. "/dev/disk2"

$ diskutil unmountdisk /dev/disk2

unmount disk.

$ sudo dd bs=4m if=ubuntu-16.04.1-desktop-amd64.iso of=/dev/disk2 status=progress

write iso contents usb.

done :)

try booting that, , see how goes.

good luck!

notes:

  • bs=4m tells dd use 4mb block size
  • if= input file
  • of= destination
  • status=progress should update little during process
