You say you are trying to install Ubuntu 'on' windows 8. Does that mean you are using the wubi installer to install Ubuntu inside windows? That won't work, see the link below.


If you are trying to install Ubuntu on its own partition on a computer which has windows 8 software, your next step is to post the output you got running the boot repair, selecting the option to Create Bootinfo Summary.

Pre-installed Windows is in UEFI boot mode.
You should always boot flash drive in UEFI mode, not BIOS/CSM boot mode.
Then you can install or run fixes to Ubuntu in UEFI mode.

UEFI should give two boot options for flash drive. You may have to turn secure boot off and enable USB port boot. Some systems require passwords to let you change those settings. But never lose that password if yours requires that.

What brand/model system? And what video card/chip?
