I want to install Ubuntu 14.04. I have a Toshiba laptop with Win 8. It will not boot from the usb stick. I want a dual boot. I do not want to wipe out Win, mainly because it is not my computer.

I can change the UEFI to CSM. That will let Ubuntu install from the usb, but Win 8 will not be included in the grub boot screen.

How to get Ubu 14.04 installed with dual boot? Apparently the problem is UEFI which seems not to want to share the boot. Microsoft trying for a monopoly again??

how did you create the usb stick? This tells how to make a bootable usb stick using windows. http://www.ubuntu.com/download/deskt...ick-on-windows You will also most likely need to disable secure boot. Free up some hard drive space by shinking windows before installing. Then at the partition stage of installation I believe there is an option to use free space for installation, or install along side, but not sure. Above all else make sure you have a backup plan just in case windows gets nuked.
edit: There should be an option to boot usb from the efi menu, will have to hit either esc or one of the f keys.

The usb stick was made by Ubuntu's own usb stick creator.

Actually, I already tried. Windows is still there, but not present in the grub boot screen. I am not the only one with this problem. Just reading up on UEFI I saw this in Wikipedia:

Secure boot is supported by Windows 8, Windows Server 2012, and a number of Linux distributions including Fedora, OpenSuse, and Ubuntu.

This is not true. Unless I disable secure boot, th machine just boots from Win 8.

Did you see these pages yet?

An alternate would be to install to the usb as if it were a real hard drive as opposed to a usb creator.

Thanks for that. I messed with my friends Toshiba today. Ubuntu starts fine. The boot mode for Ubuntu is CSM. If I enter the bios and change the settings in tab 'Advanced' to boot mode = UEFI and in the tab 'Security' (I think, can't remember right now) set secure boot = enabled, Windows boots. So both systems are up and running and in good condition.

The trick now is, get them both in the grub boot.

I'm thinking of a new install using this: https://wiki.ubuntu.com/USBStickUEFIHowto from your link.

But the first stumbling block is, I can't find usb.img. Not on my computer, not on the usb stick. What are they talking about? Is the page out of date??

you can try to Found this suggestion by from various web sites.

In the first part of that page a statement was used that had the phrase "usb.img" or "/path/to/usb.img". I'll have to assume they really mean the original file you downloaded. They could have made that better.

The file you have is a hybrid file. In a normal sense it is a cd image. It has also been modified to be usable in some usb direct installs by dd or other bit by bit copy.

Moved: This thread is more suitable in <Ubuntu> and has been moved accordingly to help your thread/question get the exposure it deserves.

@Jefro: In Ubuntu, there is no file to download. Just call up Startup Disk Creator, put in a usb stick, and it creates the bootable drive. I don't know how it does that. I could download an iso image and follow the instructions in the link. Is that what they mean? But then to get that on the stick and bootable, well I'm not an expert at this!

@ colorpurple: Thanks for the tip, I will try that, see what happens!!

Then you need a live image. Either take the cd/dvd that you have and make an iso or get a new file.
