unsuported Ubuntu 12.10

Question

I installed Ubuntu 12.10 (not realizing it was an old unsupported version). I lost access to windows 7 at boot up (it messed up the boot up drivers) have since downloaded Ubuntu 14.04.3 How do I install the latter version?

Answer 1

Create a bootable usb drive of the Ubuntu 14.04.3 and install it on your system.

Use dd:

sudo dd if=/iso/file.iso of=/dev/sdb

(Make sure you replace sdb with whatever node your usb drive is)

or use Startup Disk Creator to create the bootable USB flash drive.
