Ubuntu – How to install and use Ubuntu from a USB flash drive on Windows 8?

installationuefiusbusb-drivewindows 8

I'd like to fully install Ubuntu 12.10 onto a 16GB USB 3.0 flash drive, not create a LiveUSB, but to treat the flash drive as an external hard drive.

I've read it's possible and I know my computer can boot from it. However, it doesn't work when I try. I've booted a LiveUSB from another flash drive and installed Ubuntu onto the 16GB one. It finished successfully, but when I try to boot from it and it takes me straight to Windows 8 instead. I feel I've done something when installing the boot loader.

It'd be great if I had some step-by-step instructions for:

  • how many partitions to make,
  • what kind,
  • how big, and
  • where to install the boot loader.

Use the Universal USB Installer to copy your ubuntu ISO file to your USB drive and make it bootable, and on the step 4 you set the amount of space it will use to store the changes, this way it won't revert to the default state when you boot.

(This software is recommended on the official Ubuntu guide).
